Section Ten : Multiple Frequency & Use Charts
10.2 UHF Frequency Code U2 [Export]
SWM-3000 UHF transmitters and receivers have both Group and Channel selector knobs. The channels within each
group have been arranged so that you can use up to 10 wireless units at a single location without having the units
interfere with each other.
In general, use channels from within the same group to avoid interference (Group 6 is an exception,
see NOTE 2 below). For the maximum number of units, refer to EXAMPLE #2 below.
EXAMPLE 1: The 6 channels within Group 1 are all compatible with each other. To use six UHF units at a single
location, set the receiver and transmitter as follows:
Transmitter/Receiver GROUP CHANNEL
unit #1 1 1
unit #2 1 2
unit #3 1 3
unit #4 1 4
unit #5 1 5
unit #6 1 6
EXAMPLE 2: To use the maximum number of 10 units together, use all six channels of U2 Group 4, plus
the following 4 additional channels from U2 Groups 1-5 :
Transmitter/Receiver GROUP CHANNEL
unit #7 1 5
unit #8 3 1
unit #9 5 1
unit #10 6 3
NOTE 1: To avoid intermodulation distortion (IMD) interference, all transmitters must be kept at least 6
meters from any True Mobility UHF receiver antenna.
NOTE 2: The three channels in U2 Group 6 are not compatible with each other and may cause interfer-
ence. Do not use these frequencies together as a group.

10.3 UHF Frequency Code U1 [Export]
SWM-3000 UHF transmitters and receivers have both Group and Channel selector knobs. The channels within
each group have been arranged so that you can use up to 10 wireless units at a single location without having the
units interfere with each other.
In general, use channels from within the same group to avoid interference. For maximum number of
units, see Example #2 on page 29.
