5 Best practices for successful operation

 Never attempt to operate two or more transmitters on the same frequency at the same time.

While multiple receivers can successfully tune to a single transmitted frequency, multiple

transmitters simultaneously operating on the same frequency will immediately interfere with

each other. If a goal is to create a combo system by adding an optional transmitter (one

bodypack transmitter and one handheld transmitter to work with one receiver), only one of

those transmitters can be on and tuned to the receiver at a time.

 Ensure the receiver’s antennas are properly attached, exposed (not buried within a rack) and

oriented as suggested in the Preparing the receiver section, page 17.

 Scan for open frequencies first with transmitter off. The receiver antennas must be properly

connected for best scan results.

 When scanning and synchronizing a multi-channel system, scan and synchronize one system

at a time. To begin, have all transmitters off and scan system receiver 1 first. Then turn on

system transmitter 1 and sync it to receiver 1. Leaving system transmitter 1 on, move on to

receiver 2. With system transmitter 1 on, scan system receiver 2 and tune it to the next open

frequency within the same group as system 1. Turn on system transmitter 2 and sync it to

system receiver 2. Then leave system transmitter 2 on. Follow this process while scanning

and syncing all channels within a multi-channel system.

 Always have all member sets of a multi-channel system within the same frequency band

operating in the same frequency group. Mixing frequencies (channels) from different groups

within the same frequency band is not recommended. Channels within a group are

intermodulation-free. Simultaneous operation of channels from different groups may lead to

intermodulation interference.

 If desired, use the receiver’s mic configuration menu items to set transmitter operating

parameters prior to syncing the transmitter to the receiver. If a receiver’s mic configuration is

changed since the last transmitter sync, resync the transmitter to update its parameter

settings.

 Properly setting transmitter sensitivity is key to optimum performance. Best practice: While

observing the receiver’s AF meter activity, adjust the transmitter sensitivity so that high vocal

peaks light the yellow LED segment. Under extremely loud vocal peaks, an occasional red

LED segment light is OK, but a solid and constant red LED should be avoided.

 Choosing transmitter low or high power: The transmitter in your set may have two output

power setting options (8M band has only one). The higher setting may not be appropriate for

your application as it is possible that high may be too high based on the distance between the

transmitter and receiver antennas, or other systems within close proximity in a multi-channel

system. Low is likely to be sufficient when the set is in a small to medium size room or space.

High may be the best choice for large rooms or spaces where the distance between

transmitter and receiver antennas is substantial or existing RF conditions limit the range
