NHM-1 GSM Tuning Guide

General Remarks on GSM RF tuning

• RF tunings must be made in the same order as shown in this docu-

ment. The order of the menu items in the Phoenix service sofware may

be different.

• If baseband tunings are needed, they should be made before the RF

tunings

• After tuning is complete the mode must be set manually to dual mode.

This must be done to ensure that phone is not registering only to

WCDMA mode!

• Avoid unnecessary tuning – factory tuning values are always the most

accurate ones.

• Views in this document may change as the service software is devel-

oped. Please refer to the Phoenix help files, phone model specific ser-

vice manual and bulletins for help.
