problems, switch outages, and switch reboots.

Cisco Unified Communications Manager. Power cycle the phone to reset
the time or date.
The time shows in either 12 hour or 24 hour format.

After applying a Cisco Unified Communications Manager upgrade or
patch, that is older than the current Cisco Unified Wireless IP Phone
firmware, the phones could automatically downgrade to the load contained
in the patch. Check the Cisco Unified Wireless IP Phone default image in
the TFTP folder to fix this problem.
