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.

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.
