3.5 CLOCK BATTERY EXPIRATION
The user may examine the internal Clock Battery expiration date from this menu.
Every two years ADS will change the battery and re-test the recorder at no
charge.
3.6 UPDATE RECORDER SOFTWARE
This button will load the firmware that is on the hard disk into the RECORDER.
This should be done as soon as possible when a new release is sent.
Reloading the firmware does not erase the recorded data and parameters.
Hence if you are having trouble with your unit, it is safe to reload your
firmware. Refer to Appendix-D.
3.7 MEMORY DIAGNOSTIC
The memory test should be run periodically, (about once every 90 days) to
identify failed chips. The recorder is still usable with a couple of bad chips
however, since ADS will repair any unit at no cost, it is recommended that the
recorder be sent back to ADS at your earliest convenience.
