11.     Preventative Maintenance

      Total Recall needs regular maintenance to ensure its performance is maintained. As with any computing device, Total Recall has a fan that provides airflow across the processor to keep it cool and a filter to ensure that the air is clean. Every 3 months a message will appear on the Total Recall screen to indicate that filter maintenance is required. The filter will need to be washed in warm soapy water and then rinsed thoroughly and allowed to dry completely prior to being replaced. After maintenance is complete, select OK to remove the message.
