Troubleshooting: If –8 dBm cannot be attained, troubleshoot Cell TX as described in the
beginning of this chapter.

TN G_Offset Cell MD

See description of previous tuning. This step reports G_Offset.
The result is the value of G_Offset which gives –8.0 dBm transmitted power.
Manual Verification: See previous tuning. The value of G_Offset needs to be -8 dBm on
the center channel.
Troubleshooting: If G_Offset is not within the limits, troubleshoot the Cell TX as
described in the beginning of this chapter.

TN AMPS PL2 Po Mid (or Low, LowMid, MidLow, MidHigh, HighMid, or High)

This procedure tunes the AMPS transmit Power Level 0 on seven channels by adjusting
TxdBCtr. The channels are: Low= 991, LowMid= 107, MidLow= 245, Mid= 384,
MidHigh= 521, HighMid= 660, High=799. The algorithm then interpolates between the
measured points for frequency compensation.
The result is measured transmit power in dBm for power level 0 on each of the seven
channels.
Manual Verification: Set the phone to local mode and turn on the AMPS transmitter to
the channel which failed.
Using the Phoenix "RF Tuning" window, set "mode" = RF Tuning, and select this test.
Adjust TxdBCtr in the "values" dialog box until the output power is within the limits
(adjusting for cable loss).
Troubleshooting: Troubleshoot the cell transmitter as described in the Probing/Trouble-
shooting Tables and Diagrams section, setting the TX AGC values to those listed for
