CHAPTER 4 Specication
Battery Pack B-569 (Option)
Item Description
Capacity 7.2V/290 0mAh
Battery type Lithium secondary battery
Running time When using the LCD display: approx. 6 hours
When using the screensaver: approx. 7 hours
* 1-sec sampling, capturing to internal memory (SD1), new battery pack, and +25°C
environment.
* The running time depends on the operating environment.
* When the empty battery is charged in the GL220/820/900, the charging in about
80-90% will stop. Once disconnect and connect the AC adapter, or remove and
insert the battery pack. The battery pack charging is started in order to charge up
to 100%. (It depends on the remaining capacity.)
Charging method Mount in the main unit
Time required for charging approx. 4.5 hours
Switchover in the event of a power
failure
Because the battery is used together with the AC adapter, the power supply will be
switched automatically to the battery in the event of a power failure.
* The AC adapter is the primary power source.
Operation environment Running on battery: 0 to 40°C, Battery being charged: 15 to 35°C
Other functions • When the battery is running low, le is closed automatically.
• Remaining amount indicator
