Phone Installation

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.

Note

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.

    Charge Battery with AC Power Supply

    You can charge your battery quickly by connecting the AC power supply to the phone. To accommodate different AC power receptacles, you must insert the appropriate AC plug adapter on the AC power supply.

    You can use the phone while the battery is being charged. After the battery is charged, you can unplug the power supply cord, or you can leave the phone plugged into the power cord.


    Note

    Depending on configuration, your phone may automatically power off when it is connected to an AC power source. AC power sources include the power supply, desktop charger, or multicharger. If the phone is in use (during a call or is using an XML phone service) when it is connected to the AC power source, it powers off after the call or phone service terminates.

    For more information, ask your system administrator.

    To charge the battery in the phone using the AC power supply, the following figure shows the steps.



    Procedure
      Step 1   Lift the mini-USB port cover (bottom of phone).
      Step 2   Swing the port cover to one side.
      Step 3   Insert the AC power supply mini-USB connector in the port.
      Step 4   Insert the AC plug adapter in the slot on the power supply.
      Step 5   Insert the AC power supply in a wall outlet.
      Step 6   Verify that the indicator light is red. The light indicates the charging status:
      • Red: Battery charging in process
      • Green: Battery charging is complete

      Charge Battery with USB Cable and USB Port on PC

      You can charge the battery in the phone by connecting your phone with a USB cable to a USB port on your PC. Charging takes longer when you use the USB port on the PC to charge the battery.

      To use the USB cable and USB port to charge the battery, the following figure shows the steps.



      Procedure
        Step 1   Insert the mini-USB connector on the USB cable into the phone.
        Step 2   Insert the USB A-type connector into the USB port on your PC.
        Step 3   If the Found New Hardware Wizard opens,
        1. Click Next to use the wizard dialog box.
        2. In the Update New Software dialog, click No, not this time, and click Next.
        3. Click Install the Software automatically (Recommended) and click Next.
        4. After a few moments, the Cannot Install This Hardware dialog box appears. Click Don't prompt me again to install this software.
        5. Click Finish to close the dialog box.
        Step 4   Monitor the indicator light after the phone briefly displays USB Connected on the status line.

        While the battery is charging, the indicator light is red. When the battery is fully charged, the indicator light turns green.

        After Battery Is Charged

        After charging the battery, you must turn on the phone to make and receive calls.

        Tip

        Your idle phone screen can turn off after a time interval. To alert you that the phone is still turned on and connected to the wireless network when using battery power, the indicator light flashes green every 2 seconds.

        Power On Phone

        Procedure
          Step 1   Press and hold the (red button) until the phone powers on.
          Step 2   You might need to enter a username and password to access the wireless network.

          After completing authentication and registration with Cisco Unified Communications Manager, the phone displays the main screen and is ready to place or receive calls.

              Headset Information

              To use a headset, see Handset, Headset, and Speakerphone. Although Cisco performs some internal testing of third-party wired and Bluetooth wireless headsets for use with the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G, Cisco does not certify or support products from headset or handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed, there is not a single "best" solution that is optimal for all environments. Cisco recommends that customers test the headsets that work best in their environment before deploying a large number of units in their network.

              Cisco recommends the use of good quality external devices, like headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of these devices and their proximity to other devices such as cell phones and two-way radios, some audio noise may still occur. See External Devices Usage for more information.

              The primary reason that a particular headset would be inappropriate for the Cisco Unified IP Phone is the potential for an audible hum. This hum can be heard by either the remote party or by both the remote party and you, the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, electric motors, large PC monitors. In some instances, the mechanics or electronics of various headsets can cause remote parties to hear an echo of their own voice when they speak to Cisco Unified IP Phone users.

              Bluetooth Wireless Headsets Notes

              Using Bluetooth wireless headsets likely increases battery power consumption on your phone and may result in reducing battery life.

              For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but some barriers, such as walls or doors, and interference from other electronic devices, can affect the connection.

              Audio Quality

              Beyond the physical, mechanical, and technical performance, the audio portion of a headset must sound good to you (the user) and to the party on the far end. Sound is subjective and Cisco cannot guarantee the performance of any headsets, but some of the headsets on the sites listed below have been reported to perform well on Cisco Unified IP Phones.

              Nevertheless, it is ultimately the customer's responsibility to test this equipment in their own environment to determine suitable performance.

              For information about wired and Bluetooth wireless headsets for your phone, see the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Accessory Guide and these web sites:

              Secure Phone with Lock Set and CableLock

              You can secure the phone to a desktop by ordering the lock set from Cisco. For more information, refer to the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Accessory Guide.


              Note

              The lock set does not include the cable lock.



              Procedure
                Step 1   Put the security cable around a post or through a hole in the desktop. Insert the loops at the ends of the security cable through the C-ring.
                Step 2   Insert the C-ring with cable loops through the slot on back of phone.
                Step 3   Use the combination lock to secure the ends of the C-ring around cable loops and phone.
