Power Requirements
When a PKM IM is attached to the telephone, the telephone requires the Mitel Universal 24 VDC power adapter, part
number 50005300.
If necessary, contact your system administrator for assistance before connecting the PKM IM to the centralized power
source.
Make sure the PKM IM is plugged into an uninterruptible power supply (UPS). If the PKM IM is plugged into the UPS
and the power fails, it should remain powered on for about 10 minutes. If the PKM IM is not plugged into a UPS and
the power fails, the current call is dropped and you will not be able to use the telephone until the power is restored.
Software Updates
The telephone may require occasional software updates when new versions are available. The telephone is
configured to download the updates automatically. Contact your system administrator for more information.
