      Dock Phone in Charger

      When you undock the phone, Bluetooth disconnects and the phone uses the local speaker for audio.


      Note


      If the Bluetooth disconnects when the phone is docked, undock and dock the phone again.


      Before You Begin

      The Cisco Unified Wireless IP Phone 7925G Desktop Charger must be connected to an electrical outlet or have a charged, spare battery installed.

      Procedure
        Step 1   Place the phone into the charger, as shown in the following figure.

        When the phone docks and pairing has been set up, the Power LED flashes blue. While the Power LED flashes blue, the phone and Cisco Unified Wireless IP Phone 7925G Desktop Charger are pairing. When pairing completes, the Phone LED lights solid blue and the phone displays the dock icon .

        If you are on a call when you dock the phone,

        • If the Cisco Unified Wireless IP Phone 7925G Desktop Charger is powered, there is a slight delay while the Bluetooth connection completes, and then the call continues using the Cisco Unified Wireless IP Phone 7925G Desktop Charger speaker.
        • If the Cisco Unified Wireless IP Phone 7925G Desktop Charger does not have power (electrical output or spare battery), the phone cannot connect to the charger using Bluetooth. The call continues, but you need to undock the phone to continue the call.

        Charge Spare Battery

        Use this procedure to install a spare battery so that it can be recharged. After the spare battery is fully charged, you can use it as a power source (for a limited time) for the Cisco Unified Wireless IP Phone 7925G Desktop Charger.

        Prerequisites

        • The Cisco Unified Wireless IP Phone 7925G Desktop Charger must be plugged into the electrical outlet.
        Procedure

          The Battery LED lights green if the battery is charged, or red if the battery is charging.

          Step 2   If the Battery LED does not light up as red or green, check that the battery was installed correctly (label side up). You may need to remove the battery, reorient it, and reinsert it firmly against the contacts.

          Cisco Unified Wireless IP Phone 7925G Desktop Charger Notes

          Unplugging the Cisco Unified Wireless IP Phone 7925G Desktop Charger from the electrical outlet has the following consequences:

          • As long as a charged spare battery is in place, the station functions normally. The spare battery provides power for the speakerphone.
            • When the Battery LED starts flashing amber-yellow, the charge on the spare battery is low. Active calls continue and new calls can be placed, as long as there is sufficient power in the spare battery. When the spare battery power is low, the speakerphone does not operate, but calls can continue.
            • When the Battery LED flashes amber-yellow and dims, the spare battery charge has dropped too low. Active calls disconnect and new calls cannot be placed. The Cisco Unified Wireless IP Phone 7925G Desktop Charger should be connected to an electrical outlet or a charged spare battery installed.
          • If an uncharged spare battery is in place, the station does not function. The Cisco Unified Wireless IP Phone 7925G Desktop Charger must be plugged into an electrical outlet, or a charged spare battery installed.
