3. Managing and Playing the Recordings
 
3.1 Managing and Playing Recordings with a PC
        The TeleCorder does not require a PC for setup, recording or playing back recorded conversations. However, you may find it more convenient to operate it from a PC. With a PC you will also be able to convert recordings to standard wave files and archive them to storage on your PC. Playing selected recordings from a PC will not inhibit recording or simultaneous playback of recordings from the TeleCorder using its built-in HandyPlayer.
        The PC does not have to be On or connected to the TeleCorder for it to function. Connecting the TeleCorder USB cable to your PC and/or turning the PC power on or off will not stop the recorder from functioning. You can also disconnect the TeleCorder USB cable from a PC and connect it to a different PC without interrupting the TeleCorder operation.

a. Connection:
        Connect the TeleCorder to the USB port in your PC using the provided USB cable. The PC used for managing/playing must be equipped with an available USB port, sound card as well as speakers, and use Windows® operating system 98SE/ME/2000/NT/XP.

b. Using the Utility Software:
        You must install the supplied utility TeleCorder Manager/Player software from the provided disk to your computer prior to being able to manage the recorder from the PC or playing recordings through PC control (see manual page 6, Section 5, Installing Software and Connecting to a PC). The first time that you connect your PC to your TeleCorder, you may be asked to install the USB device driver. This driver should have been copied to your PC during install. If not, use the CD supplied with your TeleCorder to install the required USB driver following the instructions displayed on your computer.
        After installing the software, place a short cut icon on the desktop for easy access (if it was not automatically installed during install). Click the software icon or the short cut created during the install and the recordings will be listed in the main window (as shown in the following screen image). The listed information includes the ITEM or sequential recording number, the PORT that was the source of the recording, CALLER ID NUMBER or DIALED NUMBER (if available when the recording was made), DATE and TIME the recording started, and the DURATION of each recording in minutes and seconds. All records are listed in the reverse order so that the most recent recording is indexed as item number 1.
You can drag the slider bar on the right side of the display window to view the un-displayed part of the list. On the lower part of the form, there are buttons for Refresh, Re-Order, Find, Files, Hardware, Lock/Unlock, and Exit.

 
These buttons provide the following functions:

c. Refresh: Refresh the list to display the latest recordings in the TeleCorder at any time.

d. Re-Order: User can select one of the following ordering rules to re-order the list.
1. Recorded – provides a list based on the time recordings ended.
2. Starting Time – provides a list based on the time recordings started.
3. Record Duration – provides a list based on the length of recordings.
4. Channel Number – provides a list based on the channel number.
5. Un-Answered List – provides a list of calls on phone lines that were not answered. (Un-Answered Listing is not supported with TC-02F & TC-04F).

e. Find: You can search the records using a specific caller number or dialed number and/or within a date range that you input.
        In the dialogue box, you can enter search conditions such as date range, digits from a phone number such as 010, 6256 etc. The searched results will display on the screen after you select “Start Search”.
        You may also enter only a start and stop date range and all of the recorded items during the date range will be displayed.
        The recorded items after a search can be played or used for further searching and for making Wave files in a batch job. Refer to the File Copy for more details.

f. Files: This button provides the following functions for the displayed files.

 g. Conversion of recordings to WAVE files and saving to PC
        Wave Files are a widely used and supported multimedia File Format for the PC and other computer systems. Since the TeleCorder uses a unique format for saving the recordings in digital form, digitally converting them is a better way to exchange information with other systems that do not have TeleCorder software. You can use your PC to send audio recordings via e-mails or make backup CDs without worrying that others may not be able to play them.
        There is an option to save individual recordings when they are selected for playback (select the button with red dot from playback menu).

There are 3 choices:
        All ---- Copy all of the records listed in the form, including both the ones displayed and the ones not displayed. This button would be used to copy all recordings retrieved by a search.
        Last Month ---- The software will search again from all of the records in the TeleCorder within the 1st and 31st of last month, then perform a batch job to generate the wave files. This function is specially designed for users to make monthly backups.
        Last Week ---- The software will search again from all of the records in the TeleCorder within the last week, and then it will do a batch job to generate the wave files.
        Help ---- Produces a window with more detailed information about converting to wave files.
  
        All the generated files will be placed under the file folder of WaveFolder 00-99 using the present path. The last two numbers in the folder name will be produced automatically by the software. You can also browse the files within all the WaveFolder XX folders. The newest folder would be named with the highest number.
        Each file refers to a unique record. The name of each file contains date and time of the call, caller or dialed number such as File P2 10-26-04 09=11=10 DIAL TO 18609280377.WAV (recording made on TeleCorder Port 2 on October 26th, 2004 at 09:11:10, call was outgoing and dialed to 1-860-928-0377) . The files are suffixed with “.Wav”. You can change the file names as required, but you should not change the suffix unless there are special requirements.

h. Print and Save the List of Records: The displayed list on the screen can be printed or saved into a “.txt” file. No matter how the call list is re-ordered, the searched and sorted list can be printed.

i. Delete Recordings: The recorded calls can be selectively or entirely deleted. To avoid unauthorized deletion, the password must be entered before deleting recordings. If no password has been set, you will need the master password that was supplied with your TeleCorder. Options are to delete the most recent recording, all recordings, or a selected range of recordings. Deleted recordings cannot be recovered.

j. Hardware: From this button you can access all of the recorder’s hardware and information settings:

k. Hardware Information: From this sub-button you will gain information about the TeleCorder including version number, capacity, media’s usage, recorded call items, deleted call items, etc.

l. Date/Time Setting: From this sub-button you can read and set the real time clock in the recorder.

m. Recording Mode: From this sub-button you can read or set the quality of recordings.
        Mode 0 --- Large file, Good audio.
            8bit linear PCM mode, 28.8 MB/hour
       Mode 1 --- Tiny file, Poor audio.
            2bit ADPCM mode, 7.20 MB/hour
        Mode 2 --- Small file, Good audio.
             3bit ADPCM mode. Default mode set from factory,
             10.84 MB/hour
        Mode 3 --- Large file, Best audio.
             8bit nonlinear PCM mode, 28.8 MB/hour

n. Limitation for List Displaying: From this sub-button you can select the number of recordings that will be listed on the PC. To speed up the list refresh process, the default setting is 2000. This setting will cause your PC to display the most recent 2000 recordings after a refresh. You can select a different number, such as 10000, 32768 or 65536. This selection is saved in software, not as a hardware setting.

o. Caller ID Detection Settings: From this sub-button you can set (turn on/off) the caller ID detection features.
        Pre-Ring DTMF Detection: If the local caller ID mode is DTMF and sent before the ring, you must turn this feature on. Otherwise, if erroneous caller numbers are sometimes received, you should turn this feature off.
        Pre-Ring FSK Detection: If the local caller ID mode is FSK and sent before the ring, you must turn this feature on. Otherwise, if erroneous caller numbers are sometimes received, you should turn this feature off.
        Forced FSK Between Rings: If your caller ID signaling is FSK and sent between the rings, you must turn this feature on. This is the normal setting for North America.

p. Volume Balance Setting (Dava): For recorded audio in the recording mode 1, 2, or 3 (see above) the player can provide Dava --- Digital Automatic Volume Adjustment capabilities. This is done in software, not hardware. There are 2 possible settings.

        Dava for File Conversion: This setting is normally used to enable Dava when converting batches of files to wave files.

Dava Depth for Play and File Conversion: This setting can provide better audio quality but less balance in audio levels. This switch will take effect both for playback of recordings and for batch file converting of recordings to wave files.

Dava --- If the volume levels of the 2 sides of a conversation are different, or if the line quality is not well adjusted, the Digital Automatic Volume Adjustment (Dava) function will amplify the lower or far side to more closely match the level of the stronger or near side of a recorded conversation during playback. Since background noise will also be amplified together with the sound, there will be a compromise to permit weak voices to be played at higher levels without raising background noise levels to objectionable levels.

q. Lock/Unlock: This button provides access to security settings
                            for the recorder.
                 Lock: After the recorder is locked, it will ask the user
                            to input a password each time a user tries to
                            access the recorder. A password must be
                            entered to use this function.
                Unlock: To unlock the recorder so that a password
                            is not needed, the password must be entered.

r. Modify Password: The recorder comes with a factory-set password, which is in the machine code that is set by its hardware and cannot be changed. This password is written on a sheet that comes with the recorder and will be an effective password forever (keep this password in a secure place). The TeleCorder also allows you to set a second password that can be easier to remember. Use the Modify Password button to set a second password of 6-8 characters. You must enter the factory-set password prior to being given the opportunity to add a second password. After the second password has been set, it will have the same effect as the first password. The new password is also stored in the hardware of the recorder so that it will work even if the recorder is connected to, and used with, another PC. Use UnLock to disable 2nd password.

s. Built-in Keypad Password: The built-in keypad uses a 4 digit password that is stored in the recorder hardware. Although this password can be modified using the keypad, this button provides a second way to set the keypad password. Set it to “0000” and you will no longer be asked for a password.

t. Play Recordings from List: When playing recordings, buttons in the lower part of the screen will be swapped to a new set of buttons that are used to control various playback functions, as shown in the following image. The playback will start immediately. If it is a long recording, the playback function buttons will not show until the recording has been completely transferred from TeleCorder to the PC.

The functions of these buttons are:
        Dava: Click the “aVa” button and the recorded audio will be processed and played from the beginning with Automatic Volume Adjustment. You may also drag the horizontal slider bar to move the playback start point.
        Save as Wave File: Click the button with a red dot to save the selected recording to your PC. The following image shows the dialogue box you will see if you click the red dot make wave file button in the dialogue box. The recordings will be saved by default with a file name containing port number, date and time of the call, and caller ID or dialed numbers. There will be an option to rename the file when converting to a wave file.

 Rewind: Click the button with the arrows pointing to the left to
                jump backward in playing time.
Pause/Play: Click the button with two vertical lines to pause
                playback. Click again to resume.
