Power Guard/Spare Battery Charger Feature
Your phone can use the spare battery in the base unit to provide operational backup in the event of a
power failure. With a fully charged battery in the spare battery charger, you will still be able to place
and receive calls from the handset for up to 1.5 hours.
The spare battery can also be used to replace a drained handset battery, ensuring uninterrupted use.
A spare battery can be purchased from most retail stores that carry electronic equipment.
1. Open the spare battery compartment by pressing the lever on the cover as shown below in diagram
one. Then pull the compartment cover up, as shown in diagram two.
2. Align the two holes in the plug with the socket pins, then snap the plug into place. Place the battery
in the charger as shown in the diagram below.
3. Replace the spare battery compartment cover. The spare battery takes 16 hours to fully charge a
drained battery.
