TeleCorder Manual (TC-02F & TC-04F, with HDD & USB V2.42) — PDF  

3.   Setup via USB Connection to PC
3.1     Open Software and run the TeleCorder program by clicking on the icon on your PC desktop that was created when the program was installed or from the programs list if the icon is not on your desktop. 
 
3.2    Recording Process
        When connected to standard telephone lines, the TeleCorder will automatically record the telephone number called in or dialed out, time duration of the call and the voices of the conversation. You don’t need to change your procedure for making or receiving your calls. Nevertheless, the following points should be considered. When connected to phone lines, channels should be set to start/stop recording using the voltage sensing mode, not the VAR mode (hardware set-up from key-pad, or Hardware screen using a PC).
     a)      If Caller ID numbers are not displayed, confirm with your telephone company that your phone lines have the caller ID feature enabled. Otherwise, there will not be caller phone numbers recorded and displayed when managing the recordings. If you are connected to telephone handset audio, the recorder will not show caller numbers and will only show dialed out numbers if the handset has standard DTMF tones when dialing. Also check to be sure phone line channels are set for voltage sensing, not for VAR start/stop.
     b)      Always wait to answer a call until after the second ring so that the phone number from the calling party can be received and stored with the recording. 
     c)      When channels are set to start and stop recording using voltage sensing, outgoing calls will not be saved unless they are longer than 8 seconds and contain a minimum of 3 dialed digits (DTMF tones). This feature minimizes false recordings and does not apply when using Voice Activated Recording (VAR).
 
3.3    Setting for Phone Line or Voice Activated Recording (VAR)  
          When you first connect a new TeleCorder, default settings for all channels will be for Voice Activated Recording (VAR). Channels connected to phone lines should have their start/stop mode changed to the voltage sensing start/stop mode. In this mode, instead of monitoring audio levels, the recorder will monitor for DC voltages on the selected inputs to indicate on-hook and off-hook status. The phone line voltage is high when the circuit is not in use and will drop to a lower voltage when it is being used. Any channels set for on-hook/off-hook voltage sensing that are not connected to a phone line will not show any recordings due to the lack of the DC voltage changes that are required to initiate a recording in this mode.
        If you connect any of the TeleCorder inputs to audio sources that do not have standard on-hook/off-hook voltages, these channels must be set for audio or voice activated recording (VAR).
 
3.4   VAR Settings (Voice Activated Recording)
        Recorder channels set for the VAR mode will detect the voice level on the line to start a recording. It will start recording when a preset audio level is reached (normal conversation levels), and stop after the audio drops below this threshold (no sound other than weak background noise) for a preset period of time. The length of quiet required for the recording to end is called “turn off delay”. 

 
3.5    Setting Channels for Operation in VAR Mode
        You can use either your PC or the keypad built into the TeleCorder to select Phone Line recording or VAR mode, and to change and confirm these and other operating parameters.
  
3.6   Configuring TeleCorder using a PC 
          Using your PC with the TeleCorder program running, select Hardware from the main screen. You will open the Hardware Information screen as shown here. From this button you will gain information about the TeleCorder including version number, capacity, media’s usage, recorded call items, deleted call items, etc.

3.6.1      Channel/Port Setup:  Each channel (Port) in the recorder can be set to start and stop recording using either audio activation (VAR) or voltage sensing. Channels showing a check mark in the boxes labeled Port 1, Port 2, Port 3, or Port 4, are set for VAR recording. Channels with no checkmark indicate they are set for phone line recording. For any channel you want to start/stop recording using
the phone line voltage sensing mode, click on the box for that channel to remove the check mark, then click the Write Hardware button to confirm any changes. With 2 channel TC-02F, disregard Port 3 and Port 4 settings. 

3.6.2     VAR Voltage Threshold:  Set the threshold level to match the audio level on your audio source.
    L0: Extra Sensitive, suitable for weak audio sources with low background noise level (for example, with weak earphone or line-out recording).
    L1: High Sensitivity, suitable for normal line level audio sources with low background noise levels (normal phone handset earpiece audio or weak speaker of radio).
    L2: Mid Sensitivity, suitable for higher than normal audio levels and/or higher background noise levels (for recording from a noisy phone line when voltage sensing cannot be used due to non-standard voltages or with normal speaker audio from a radio).
    L3: Low Sensitivity, suitable for very high audio levels, and high background noise levels. Recording may stop if audio levels are too weak (phone recording with non-standard and very noisy DC voltages, or extra loud radio audio).
 
        After making changes, click the button labeled Write Hardware to confirm any changes. You may be asked to quit the program and try again. You may also need to un-plug and re-connect the TeleCorder power or USB cable to successfully change the TeleCorder operating parameters.
   
3.6.3      Turn Off Delay Time:  If any channels have VAR selected for recording start/stop, also select one of the four turn-off-delay options (VAR Turn Off Delay): 4, 12, 32 or 100 seconds. This setting will help to prevent recordings from ending during quiet periods. Click the Write Hardware button to confirm any changes.
 
3.6.4       VAR Timeout:  If any channels have VAR selected for start/stop, set the timeout to one of the four choices: 20, 40, 60 or 80 minutes. This setting will limit the maximum length of a recording for easier management of long conversations or for when recording from broadcast radio where pauses may not be long enough to separate individual recordings using VAR for start/stop. If a recording reaches the maximum length of time that you select for VAR Time Out, that recording will end, and a new recording on that channel will begin. Click the Write Hardware button to confirm any changes.
 
3.6.5      Save VAR and Outgoing Calls Less than 8s or Outgoing Calls with Less than 3 DTMF Codes: 
Click on this option to place a check mark in its box if you want to save recordings that are less than 8 seconds long. If this box is not checked, VAR recordings shorter than 8 seconds, and outgoing telephone calls (using voltage sensing for start/stop) with less than 3 DTMF digits, will not be saved.
         This setting is normally used if external noise causes frequent and unwanted false audio activated recordings, or if telephone line testing produces short off-hook conditions that are not associated with actual phone line usage. It is normal to record all activity on the monitored circuits. Use care when setting to delete short recordings. This setting can only be changed from the PC. It cannot be changed from the keypad.              
 
3.6.6      Hardware Information:  Click on this box to show information about your TeleCorder: hardware version, model type, number of calls recorded, number of calls deleted, total length of all recordings (in hours, minutes and seconds), total length of deleted recordings, and percentage of storage space used. Information displayed for number of files and duration is for files shown on the current list on the PC.
   
3.6.7      Date/Time Setting: Click on this box to copy the date/time setting from your PC to the TeleCorder.

3.6.8      Audio Recording Mode: From this sub-button you can set the quality of recordings.
                 Mode 0 --- Large file, good audio.
                               8bit linear PCM mode used in the 1^st generation recorders.
                 Mode 1 --- Tiny file, poor audio.
                               2bit ADPCM mode.
                 Mode 2 --- Small file, good audio.
                               3bit ADPCM mode. Default mode set from factory.
                 Mode 3 --- Large file, best audio.
                               8bit nonlinear PCM mode.
      
3.6.9      Limitation for List Displaying:  From this sub-button you can set the list display features to speed up the list refresh process or to have more items displayed in the lists of recordings shown on your PC in the main TeleCorder program screen. The default setting is 2000 for fastest speed. You can select a different number, such as 10000, 32768 or 65536, respectively. This selection is saved in software, not as a hardware setting.
 
3.6.10      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.
   
3.6.11     About TeleCorder PC S/W:  From this sub-button, you can see additional information about the TeleCorder software.
 
3.6.12     QUIT:  Use this sub-button to exit the Hardware Information & Settings window.
 
3.6.13    Notes:
    1.    The above settings must be locked into the TeleCorder hardware by restarting the recorder. After any of the above settings are changed, they will not take effect until the recorder is restarted by turning off or disconnecting AC power to the TeleCorder, waiting a minimum of ten seconds, and powering the TeleCorder back on. Any changes made in software should now be locked into the recorder’s internal memory.
    2.     To avoid interruption of active recordings, you should only set the above items while the recorder is idle. Wait until no channels are active or unplug inputs prior to changing settings.
    3.     After the settings have been changed, check to make sure that the recorder is functioning as expected.
    4.     The recorder listens for outgoing numbers dialed using DTMF/touch-tone signaling and stores them with the recording. It is possible for it to document and record false phone numbers when the recorder is in the VAR mode (particularly when recording broadcast radio music where the audio can mimic sounds of dialing). To avoid collecting and recording these erroneous numbers, you can use the PC interface to disable storing of dialed digit signaling.
