Charge the Handset Battery
You use the handset charger to charge the handset battery. The battery comes partially charged, but you should
charge it for a minimum of 10 hours before you use it for the first time. If you don't fully charge it, you may
decrease the life of the battery.
If you remove and replace the battery from the handset, you need to fully discharge and then fully charge the
battery so that the battery indicator is accurate.
Caution Charge the battery with the handset charger provided. If you use another method, you can damage the battery,
the handset, or your surrounding area.
Only charge the battery in environments where the temperature is between 32°F (0°C) and 104°F (40°C).
Do not charge the battery in hazardous environments or where there is explosion danger.
When you place the handset into the charger, it turns on (if not already on) and displays a message that the
handset is charging. The handset screen dims and turns off at the configured time.
If the LED on the handset starts to flash, the handset is updating its firmware.
Before you begin
Ensure that your handset charger is plugged into the electrical outlet.
Procedure
Step 1 Place the handset in the charger so that the contacts in the handset and the contacts in the charger
match.
The handset screen should turn on and display a message that the handset is charging. If this doesn't
happen, remove the handset from the charger and try again.
