Feedback?This Help article explains how to turn your Cisco Wireless Phone 9821 on or off, wake the display, lock or unlock the screen, and access your voice mail.
Read the Product safety and security information before installing or charging the battery.
Your phone is powered by a rechargeable Lithium-ion battery. Before using your phone, you must install the battery and fully charge it.
To operate, your phone must connect to the corporate wireless network and the IP telephony network. Depending on your organization’s setup, your administrator may configure your new wireless phone, or you may need to set it up yourself.
Once the phone is set up, it is ready for use.
Turn on your phone
When you turn the phone on, you may need to enter a username and password to access the wireless network. After the phone authenticates and registers with the call control system, the main screen displays and you can make or receive calls.

Press and hold Power/End Call |
Wake up the screen display
By default, the phone screen dims after 10 seconds of inactivity. After 10 more seconds of inactivity, the screen display turns off. When the screen display is off, the phone uses less battery power.
If the screen display is off, you must wake it up to make a call.
