After making a channel change, please make sure that the corresponding
change is made on the matching receiver also. To be exact, changes MUST be
made at both the transmitter and receiver.
9
Use only brand new Alkaline batteries. Do not use " general purpose " batteries.
When batteries are weak, replace the batteries altogether at the same time. Do
not mix and use new and old batteries together.
10
Position the receiver such that it has the least possible obstructions between it
and the transmitter. Line of sight is best!
11
The transmitter and the receiver should be as close as possible but not less
than 1m.
12
A receiver cannot receive signals from two or more transmitters
simultaneously.
13
Turn the transmitter off when it is not in use. Remove the batteries if it is not to
be used for a period of time.
