Power Guard/Spare Battery Charger Feature
Power Guard
The i 5858 uses the spare battery charger 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, for up to 2.5 hours.
The spare battery can also be used to replace drained handset battery ensuring uninterrupted
use. The spare battery is optional and purchased separately.
NOTE: When using the i 5858 during power guard mode, audio quality may be compromised
due to reduced power availability.
Installation
1. Open the spare battery compartment by pressing on the cover and sliding in the direction
as indicated on the cover.
2. Place the battery in the charger with the metal contacts aligning, as shown in the diagram
below.
3. Replace the spare battery compartment cover. The spare battery charger takes 20
hours to fully charge drained battery.
