Hardware Diagnostics
As of the 1.3(4) release, a self-diagnostics tool is available that can help with hardware analysis.
The Diagnostics menu is located under the Phone Settings menu, where the Keypad, Speaker and Microphone, Barcode
Scanner, and Wireless LAN Radio and Antenna can be validated.
The keypad diagnostics allows for a button to be pressed and released to ensure they are functional.
The audio diagnostics performs an audio loopback, so the speaker and microphone can be validated.
The WLAN diagnostics menu is the standard Site Survey utility, which will use the current network profile information to
perform passive and active scans for the configured SSID and 802.11 mode.
The scanner diagnostics will allow to scan a 2D barcode to ensure the scan engine is functional. A Reset option is available to
reinitialize the barcode scanner.
Firmware Recovery
If the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, or 7926G does no boot properly, then the firmware can be recovered
via the USB connection.
Be aware that the current settings will be reset to factory defaults when performing the firmware recovery process.
Use the following steps to perform a firmware recovery.
