Operation Manual

10.2. Operating the transmitter with Channel-Check

Once installed in the transmitter, Channel-Check carries out its work automatically

every time you switch the transmitter on. You will hardly be aware of anything hap-

pening at this stage. However, you must ensure that Channel-Check is set to check

the correct channel. Remember to ask yourself this question before you switch on

every time:

Do the crystals in the Channel-Check module and the transmitter

bear the same channel number?

The check can only function correctly if the channel number of the transmitter crys-

tal and the Channel-Check crystal are identical. If you are not quite certain, it is

always better to check one more time than make a mistake.

This is the procedure for switching on:

1. Extend the telescopic aerial fully

2. Keep about 10 m away from any other RC transmitters which are switched on

3. Switch on the transmitter

• 7 x a trill, LED flashes fast (approx. 1 per sec.), Display shows STOP means:

Your channel is in use or suffering interference.

The transmitter does not radiate an RF signal.

• only one trill, LED turns on for about 4 sec.,

then flashes slowly (approx. Every 3 sec.) means:

Your channel is vacant, and Channel-Check has not picked up any

interference. You can safely operate your model.

Note: if the channel is already in use or if interference is detected,

the transmitter will not transmit! To repeat the check you must first

switch the transmitter off and then on again.

10.3. What should I do if STOP appears and the LED flashes fast?

First enquire among the other transmitter users whether somebody else is using

„your“ frequency. It regularly happens that a modeller changes crystals one day,

and the next day forgets what he has done.

If you cannot find another transmitter on your channel, wait a few minutes and

repeat the check by switching on again.

Don’t risk a flight until you have completed a series of checks, all of them suc-

cessful (LED is on for 4 sec. after switching on and then flashes slowly). For your

own peace of mind, carry out a series of checks, walking to different locations be-

tween attempts, so that you can be confident that your channel is really free.
