Cisco 8821 Accessory Guide

• On time—The battery life is reduced when the phone is turned on. Calls, messages, application use,
Bluetooth use, and actions like menu navigation use power.
• Scan mode—Your phone can be set up to scan the access points in three different ways (Continuous,
Auto, Single AP). If your phone uses Continuous or Auto scan modes, the phone requires more power,
reducing battery talk time.
If you require longer talk times, you will find it useful to have a spare, charged battery.
