EXAMPLE 3 SCENARIO
The mobile radio was set for the wrong RX and TX frequencies. The client was assigned 471.6500 (RX), and
474.6500 (TX). The mobile radio configuration list shows TX Freq=474.5500, and RX Freq=471.5500.
NOTE: This programs channel 0.
Parameter Change Command:
In the lower message window, type the following command, then
press ENTER.
FREQUENCY=0,474.650000,471.650000
EXAMPLE 4 SCENARIO
Add another channel. The client was assigned a second channel of 474.6500 (RX) and 477.6500 (TX). The
mobile radio configuration list shows Channel=0, TX Freq=474.6500, RX Freq=471.6500. There is no second
channel.
Parameter Change Command:
In the lower message window, type the following command, then press ENTER.
FREQUENCY=1,477.650000,474.650000
Notes on frequency changes:
• The syntax is FREQUENCY=CHANNEL NO.,TX FREQ,RX FREQ
• The channel number and both frequencies must be entered even if only changing one frequency.
• If new RX/TX frequencies are greatly different, the mobile radio may operate outside the bandpass
of the receiver filters and power amplifier module deteriorating performance. The mobile radio must
be replaced with one operating in the selected frequency range.
• Additional frequencies that are not active may be detrimental to the mobile radio’s performance.
Step 7 If necessary, repeat Steps 5 and 6 to change the parameters.
Step 8 Verify that all parameter changes were accepted by the mobile radio. To do this, type
a ? in the right field and press ENTER. Compare the desired parameter changes with
those appearing in the upper message window.
Step 9 Disconnect the mobile radio and return it to service.
