Upgrading Your Phone’s Firmware

Your Polycom CX400 cordless phone handset and cradle contain firmware

that implements the phone's functionality. From time to time, Polycom may

provide updated firmware that will enhance the operation of your phone. You

or your system administrator may elect to perform the task of upgrading your

phone’s firmware.
A special cable will be needed to upgrade firmware on the handset. This cable,

along with upgrade instructions, will be made available in a Firmware

Upgrade Kit that may be purchased separately. If a firmware upgrade

becomes necessary, Polycom will make upgrade kits available. All

information will be provided by Polycom Technical Support at
