and condition of the battery. See “Status Indicator Panel” on
page 28. Install a charged battery or a Power adapter.
The battery is installed but is
faulty.
Use the Status Indicator panel to verify the presence and
condition of the battery. See “Status Indicator Panel” on
page 28. If the battery indicates a short, remove it and 
operate from another power source or replace that battery.
The battery is low. Check the Status Indicator Panel to determine the presence
and condition of the battery. See “Status Indicator Panel” on

charged or install a charged battery.

plugged in properly.
Verify that your adapter is connected correctly. See “Power

Accessories position.

auto/airline) is faulty.
Try a different power adapter.
