• Do not operate two or more wireless channels on the same frequency at
the same time and location. This would cause unwanted noise due to radio
interference.
1. Select the same "NAME" (country code) and "GROUP" on all transmitters and
receivers.
• The designation of each "GROUP" comprises a number (designating the fre-
quency band) and a letter or another number (designating the Frequency Group
as such).
Groups with a number and a letter have been optimized for systems with de-
vices operating within the same frequency band.
Groups with two numbers have been optimized for systems with devices oper-
ating in neighboring frequency bands.
• If you use devices in neighboring frequency bands, select the same Fre-
quency Group (the same number after the dot) on all these devices. Neigh-
boring frequency bands are 5/6 and 7/8.
• Switch ON any radio microphones, personal monitor transmitters, etc. (in-
cluding even those made by other manufacturers) except for your IVM 4
system! This is the only way to make sure the receiver will find frequencies
that will be free of any mutual interference during the performance.
2. On the first receiver, find the nearest clean Subchannel of the selected Fre-
quency Group:
• In SETUP mode, turn the Jog switch CW or CCW as many times as needed to
call up the "AUTO" and "CH" labels on the display.
• Select the desired Frequency Group.
• Press the Jog control to start the search for clean frequencies.
• Clean frequencies are frequencies where the receiver finds no RF signal or an
RF signal whose level is lower than the set threshold.
3. Tune the transmitter assigned to the first receiver to the same frequency that you
selected on the receiver and switch power to the transmitter on.
4. Repeat steps 2 and 3 for each IVM 4 channel.
