Adjust the jumper settings in P2++ and potmeters R338++ until the voltage is 240mV at
TP23++
.
Figure 1-7 Alternative jumper settings of P2++.
Turn off the equipment and remove the extender card. Set the MF12xx in its correct position.
Turn on the transmitters.
Adjust the RF level potensiometer on the front of MF12xx until the monitor gives a RF level
reading of 3.0V.
Repeat above for all monitor channels.
1.4.3 AGC Time Adjustment
Turn on the transmitters.
Make a note of the AGC voltages on TP 1,2,3 and 4 on MF12xx.
Turn off the transmitters.
Adjust the AGC TIM potmeter on the front of MF12xx until the AGC voltage (TP1,2,3 or 4) is
the same as with a nominal RF input.
Do this for all four monitor channels on all of the MF12xx modules in the system.
This ensures fast response from the monitors.
1.4.4 SDM Adjustment
Adjust the SDM potmeter on the front of MF12xx until the monitors reads 40.0/80.0%SDM +/-
0.1%SDM.
1.4.5 DDM Adjustment
Measure and note down the DDM values from the MCU and NF antenna with help of the Field
Test Set.
Set the Nominal values for each channel to the measured values with help of the RMM Pro-
gram.
