3. Connect a true RMS AC voltmeter to the receive audio output pair from the iRIM
to the console. (For the pinout, see Table 3 on page 17 .)
4. Measure the loss between the iRIM and the console by transmitting a tone on a
field radio or using a service monitor, and measure the level at the iRIM’s
receive audio output pair, and again at the UDCC receive audio input. This
measurement will be used in Step 8 .
5. Following the directions in the previous sections, return to the Channel A
Configuration or Channel B Configuration page.
6. Leave the Peak Level From Console setting at its default.
7. Set the Audio Level From Console to measured value in Step 2 , which
corresponds to a 60% channel deviation. The iRIM default for the Audio Level
From Console is -7 dBm.
8. Set the Audio Level To Console to the sum of the line loss measured in Step 4 ,
in dB, and the Audio Level From Console setting. This assumes the console is
expecting to receive the same audio level as it transmits. (Otherwise add the line
loss to the console’s expected receive level.)
9. Click the Submit button. This will return to the View/Modify Configuration
page.

Caution! If any changes were made to the channel parameters they
have not been saved yet.
10. The previous steps may be repeated for Channel B. Click the
Channel B
Parameters
button. This opens the
Channel B Configuration
page.
11. Click the
Save Changes
button. This saves the new configuration to the iRIM’s
non-volatile memory. The previous configuration is also preserved.
