Charge spare battery pack
Power guard feature
Your phone uses a spare battery charger in the base unit to provide power backup in the event of a
power failure or outage. With a fully charged battery in the spare battery charger, you will be able to
make and receive calls for up to 2.5 hours during a power outage.
The spare battery can also be used to replace a depleted handset battery to ensure uninterrupted use.
The spare battery is optional and can be purchased separately.
Installation
1. Open the spare battery compartment by pressing the release button located on the bottom of the
base unit.
2. Remove the battery cover and place the battery in the compartment with the metal contacts aligned,
as shown in the diagram.
3. Replace the compartment cover. The spare battery charger takes 20 hours to fully charge a
depleted battery.
