Charging the Battery

You can mount either one or two battery packs when you charge them.
Expected time required for charging:
The battery pack is charged by mounting it in the GL900, attaching AC adapter to the GL900.
(1) Mount the battery pack in the GL900 (see the previous section for the mounting procedure).
(2) Turn on the power to the GL900. (Please see Section 2.4, "Connecting the Power Cable and
Turning on the Power").
(3) The CHARGE LED lights.
CHECKPOINT
• GL900 is equipped with a temperature monitor function which starts automatic charging as soon as it
is cooled down. Therefore, depending on the internal temperature, charging may not be performed
immediately.
When charging is attempted while the power is ON, charging may not be performed immediately
depending on the temperature environment.
In such a case, set the Screen Saver settings to ON. GL900 will start charging as soon as it is cooled
down.
Charging temperature: 15 to 35 °C
• If input is being made directly from the DC power supply instead of the AC adapter, the DC voltage
must be at least approx. 16 V.
• battery pack x 1: approx. 4 hours
• battery pack x 2: approx. 8 hours
