Phone Installation Overview
Your system administrator configures your new Cisco Unified Wireless IP Phone to connect to the corporate
wireless network and the IP telephony network.
A rechargeable Lithium ion battery powers the Cisco Unified Wireless IP Phone. Before you can use your
phone, you must install the battery in the phone and charge the battery. Depending on the type of battery you
have, the fully charged battery provides the following hours of service:
• The standard battery provides up to 9.5 hours of talk time or up to 180 hours of standby time.
• The extended battery provides up to 13 hours of talk time or up to 240 hours of standby time.
Using a Bluetooth wireless headset reduces the talk time and standby time for both types of batteries. In
addition, how the system administrator configures your phone also affects its battery life. For more
information, contact your system administrator.
