GL900 USER'S MANUAL

Checks and Preparation
2.9 Using the Battery Pack (B-517: Option)
The B-517: option battery is the only battery type that can be used with the GL900.
Two battery packs need to be mounted when you have the GL900 run on batteries.
You can also mount only one battery pack when you charge it (using the AC power source). At this time, the
battery pack can be mounted on either the right or left.
The running time using batteries is about 2.5 hours when the screen saver is operating.
