APPENDIX C. SYSTEM BATTERIES
MAIN INTERNAL BATTERY
If the Internal Battery should ever require replacement, use ONLY the proper BGI Battery
(PQ103).
EXTERNAL BATTERY
The External Battery is used to provide double the Run Time Capacity of the PQ100.
CAUTION: REVERSAL OF THE BATTERY LEADS CAN CAUSE IRREPARABLE
DAMAGE TO THE PQ100.
CLOCK BATTERY
The Real Time Clock/Calender is backed-up by a Lithium Cell that will require changing once
every 2 years. It also provides power to the Alarm Clock wake-up circuit. The PQ100 will let
you know when this battery requires changing by providing a warning just prior to shutdown or
when powered on and must be acknowledged by the user. You can temporarily ignore the
warnings but a replacement should be acquired from the factory immediately. If the battery is
allowed to get too low (ignoring the warnings) you may not be able to power off the PQ100 (It
will keep waking up after a shutdown).
IF "REPLACE CLOCK BATTERY" MESSAGE IS ENCOUNTERED YOU MUST REPLACE
THE CLOCK BATTERY IMMEDIATELY FOR CONTINUED OPERATION. IGNORING
THIS MESSAGE MAY PRODUCE ERRATIC OPERATION.
