Operating the Transmitter
(continued)
1. A “PRESET” selection in the menu allows you to reset all transmitter functions to their
factory-default values.
2. Press the Set button once to move to Menu mode.
3. Press the Up arrow twice to move to “PRESET” in the LCD window.
4. Press the Set button once and “LOAD” will appear in the LCD.
5. Press and hold the Set button until “DEF” appears in the LCD.
6. Press and hold the Set button until “LOADED” appears briefly in the LCD. The window will
then revert to “PRESET”.
7. Press the Down arrow once to move to “QUIT”.
8. Press the Set button once to exit the Menu mode and return to normal operation, with all
factory-default settings restored.
Tips for Best Results
1. Use only fresh alkaline batteries. Always replace all batteries.
Do not use “general purpose” (carbon-zinc) batteries.
2. Position the dual-channel receiver so that it has the fewest possible obstructions between it
and the normal location of the transmitters. Line-of-sight is best.
3. The transmitters and the dual-channel receiver should be as close together as conveniently
possible, but no closer together than three feet.
4. The receiver antennas should be in the open and away from any metal.
5. Each transmitter-receiver pair must be set to the same frequency.
6. Only one transmitter on a given frequency should be “on” at a time.
7. The power switch on the transmitter has four positions: “Ext.,” “Off”, “1” and “Both.”
8. If the “Out Level” of either receiver channel is set too high, it may over-drive the input of the
camera/mixer or clip the output of the receiver, causing distortion. Conversely, if the receiver
output is set too low, the overall signal-to-noise ratio of the system may be reduced.
9. You need to change channels 1) when a strong interference signal is received, 2) when the
channel breaks down, or 3) during multiple-system operation in order to select an interference-
free channel. Always turn the units off before changing frequencies.
10. Turn the receiver and transmitter off when not in use. Remove the batteries during long-term storage.
