Problems with wireless communication

Obtaining a Recovery Key (U.S. only)

A disabled Norstar Companion system implies that Base
Stations and portables are not operational. UTAM registering
information is, however, retained.

To reactivate Norstar Companion communication on a
disabled system, you require a UTAM Recovery Key. To
obtain and enter the Recovery Key, follow the procedures for
the UTAM Activation Key explained in “Software keys (U.S.
only)” on page 68
.

Obtaining a Regression Key (U.S. only)

You may need a Regression Key if one of the following
conditions occurs:

a defective ICS is replaced

an ICS has lost its System Identification Number (SysID)
due to a power outage for more than 72 hours

If you need a Regression Key, follow these steps:

1. Record the new System Identification Number once the

system is powered up. See “Step 2: Obtain the System
Identification Number” on page 69
for more information.

2. Locate the following information in the MICS

Programming Record.

the original SysID

all previously entered radio and portable credit keys

3. Call Northern Telecom Customer Response Center at

1-800-321-2649 to request a Regression Key.
