Tips To Obtain The Best Results
• Use only fresh alkaline batteries. Do not use
“general purpose” (carbon-zinc) batteries.
• The transmitter and the receiver should be as
close together as conveniently possible, but
no closer together than three feet. Maintain
line-of-sight between them whenever
possible.
• Each transmitter/receiver pair must be set to
the same channel number.
• A single receiver cannot receive signals from
two transmitters at the same time.
• 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.
• Turn the transmitter off when not in use.
Remove the batteries if the transmitter is not
to be used for a period of time.
