If radio volume can’t be set on the test set’s meter screen
If radio volume can’t be set on the test set’s meter screen
❒ Check that the meter needle on the test set’s meter screen moves when you turn the
radio’s volume knob. If the meter needle doesn’t move make sure the radio is powered
on.
❒ Check that the radio is correctly connected to the test set. Refer to "Making a
Connection" in chapter 2 on page 29 for a diagram showing the correct connections.
❒ If the meter needle moves but cannot be set high enough, check to see if the parameters
for setting radio volume are correctly set up. Incorrect settings for any one of these
parameters will affect how the test runs.
1. Parameter 7, RX Audio Load Impedance is used by the software whenever radio
volume or squelch control is adjusted during testing.
2. Parameter 11, RX Maximum Audio Power sets the full-scale volume level of the
meter displayed on the test set. The value you enter for this parameter is scaled up by
50%.
3. Parameter 17, RX Tolerance for Setting Volume sets the tolerance window
displayed on the meter screen.
