          Important notes

          This section provides general information about using and supporting the Cisco Unified Wireless IP Phone 7921G, 7925G, 7925G-EX, and 7926G in your system.

          Health-care environment use

          This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.

          Debug level impact to voice quality

          Voice quality can be impaired when you set system log trace files for higher debug levels. Set only the modules that are required when capturing trace files for a phone.

          USB Connection Disabled After Powering Phone Off and On

          If you power off the Cisco Unified Wireless IP Phone 7921G, 7925G, 7925G-EX, and 7926G with the USB cable connected and then power it on again, the USB connection might fail.

          To enable the USB connection, unplug the USB cable from the phone and then plug it back in.

          Game MIDlet Impact to Voice Quality

          If you are running a Java MIDlet game application in the background during an active call, voice quality may be affected.

          Upgrade from Releases Prior to 1.4(3)

          If your Cisco Unified Wireless IP Phones are currently running a release prior to 1.4(3), then you must use the Trivial File Transport Protocol (TFTP) method to upgrade to release 1.4(3) or later. Once upgraded to release 1.4(3) or later, you can then upgrade to later versions using the phone's webpage either via USB or WLAN.
