4.5 Tuning The Audio

Tuning the Portable to Base (PTB) Audio Path:
Adjust the PTB audio by changing the PTB Audio Gain setting in the CPS. Because there is no service function
generator required to set the deviation, use this value to adjust the audio level to the mobile radio as deter-
mined by listening to the output of the mobile radio with a service monitor. Ensure that speech is approxi-
mately 60% of the total deviation of the mobile radio transmit audio.
Tuning the Base to Portable (BTP) Audio Path:
Adjust the PTB audio by changing the PTB Audio Gain setting in the CPS. Generate traffic on the mobile radio
receiver and adjust the BTP Coarse Audio Gain until the audio heard on the WM-1000 handheld is clear and
loud. Use the PTB Fine Audio Gain to adjust the audio so it is clear to the WM-1000 handheld radio.
