5.6 Receiver Tuning
There are 4 variations of Receive Squelch Tuning: 12.5 kHz-Band Normal Squelch, 12.5 kHz-Band 
Tight Squelch, 25 kHz-Band Normal Squelch and 25 kHz-Band Tight Squelch.
5.6.1 Receive 12.5 kHz-Band Normal Squelch Tuning
1.Under the Alignment menu, select Rx Squelch, then select Squelch 12.5 kHz-band Normal. 
(Figure 5-7. Rx 12.5 kHz-band Normal Squelch Tuning Window).
2.Apply a RF signal for current frequency point with minimum amplitude, -128 dBm (F1 being the 
first). 
3.Set softpot to minimum (0) and adjust the amplitude of RF signal to the range of normal squelch 
tuning (as shown in Table 5-4.) on the test equipment.
4.Adjust the softpot value by using either the Left/Right arrows on the slider or Up/Down arrows on 
the Working Softpot box until the radio is totally muted.
5.Repeat steps 2–4 for F2–F5.
6.Press Program to commit the softpot values into the codeplug.Table 5-4.  Receiver Squelch Tuning

5.7 Utilities
5.7.1 Program Serial No.
The Program Serial No. option under the Utilities heading allow the radio serial number to be 
programmed. However, the serial number of a particular radio can only be programmed if it was 
originally blank. Only New Service Boards have a blank serial number. Once a new serial number is 
programmed into the board, it is NO longer changeable. If the serial number of the radio is not blank, 
access to the screen will be denied. The serial number programming screen is shown in 
Figure 5-11. Program Radio Serial No. Window. For the new radio serial number to take effect, close 
the screen and then read the radio again.
