Phone Setup
The battery has metal contacts that must connect to the contacts in the battery compartment. The battery also
has an arrow at the bottom and the Cisco logo at the top.
When the battery is correctly inserted, the logo and arrow are visible. The arrow points towards the connector
on the base of the phone and the logo is close to the locking catch.
The battery compartment has small tabs in the bottom corners. The battery must slide under these tabs. The
following graphic shows the battery compartment without and with the battery correctly installed.
a) Hold the battery so that the lower edge is close to the bottom of the compartment. Make sure that the
metal contacts on the phone and battery face each other. On the battery, the Cisco logo must be near the
locking catch and the arrow must point to the base of the phone.
Caution
