Deregistering a portable
Deregister an extension number when:
• the portable must be replaced due to loss or breakage
• the owner departs and you want to assign the handset to
someone else with a different telephone number
Press ≠ and DEREG to deregister a DN.
Radio data
Note: (U.S. only). Before registering Companion portable
telephones you must first obtain and enter a certain
number of portable credit keys. Also, before the base
stations can be recognized by the MICS-XC system,
you must obtain and enter a UTAM Activation Key.
Please refer to Software keys (U.S. only) on page 67 of
this document before setting up your wireless system.
Re-evaluation
Re-evaluation automatically assigns the base station radios to
cells and determines which cells are neighbors. When adding
or removing base stations, Re-evaluation needs to be applied
to the system.
Tip -
This procedure does not clear the registration data
in the portable. You must also deregister from the
portable telephone itself using on-the-air deregistration.
For instructions, see the Portable Telephone
Registration Instructions or Deregistering the C3050 on
page 83.
Schedule re-evaluation during slow periods.
Plan on conducting a re-evaluation of your
Norstar Companion when the system is not busy
with calls. Wireless calls may be lost during the
re-evaluation process.
