USING THE MEMORY
1 Microprocessor Memory Backup
All memory channel data is backed up in EEPROM.
It is not lost unless you reset the memory.
All other data that you set is retained by a secondary
lithium battery that will provide memory backup for
about 20 days if you remove the battery pack or
external DC power.
A fully discharged battery will require approximately
10 hours to reach full charge after installing a
NiCd
battery pack or external power.
2 Initializing The Memory
Press and hold the M key and turn on the power to
reset the memory. All the LCD indicators will appear
on the display. Release the M key. This resets all
user programmed data to the factory defaults.
