Desktop Charger with Speakerphone

You can use the desktop charger, as shown in Figure 2, to charge both the phone battery installed in the phone and a spare battery at the same time. In addition, the desktop charger is a speakerphone when the phone is docked in the charger.

To use the desktop charger, see Figure 2 and follow these steps:

Procedure

Step 1 Plug the power supply with AC plug adapter into a wall outlet.

Step 2 Insert the connector plug into the back of the desktop charger.

The power LED on the desktop charger is green.

Step 3 Place the Cisco Unified Wireless IP Phone 7921G in the upper compartment of the charger and look for

the “AC connected!” message on the phone screen. The phone starts charging.

Step 4 Press down on the top of the phone and look for the “Docking connected!” message on the phone screen

and the docked icon in the phone status line. The phone is connected to the desktop charger speaker and microphone for speakerphone operation.

Step 5 Optional—You can also insert a spare battery into the lower slot. The battery LED is red while charging

the battery and turns green when the battery is fully charged.

Note You can insert and charge both the phone and a spare battery at the same time, or you can insert

and charge them separately.

While charging the Cisco Unified Wireless IP Phone 7921G, you can use the Cisco Unified Wireless IP Phone 7921G web pages to import or export settings. You must connect the desktop charger to your computer with the standard USB A-type to B-type cable. For more information, see “USB Cables”

section on page 13.

To remove the phone from the desktop charger, tilt the phone forward about 30 degrees, then remove it from the compartment. Proper removal insures that the connectors will work reliably.
