14. Changing the crystal

In order to avoid a double assignment of a channel it may be necessary to change the crystals
on your remote control system.
For reasons of operational safety, you should only use crystals that are explicitly
recommended for the use in your remote control system by the manufacturer.
To change the crystal, proceed as follows:
• With the transmitter turned off, pull the holder for
the transmitter crystal (1) on the back of the trans-
mitter crystal (2) out of the housing.
• Take the transmitter crystal out of its plastic holder.
• Insert a transmitter crystal (3) with a different chan-
nel in the same frequency band. Please make sure
that you place the correct crystal in the holder. Trans-
mitter crystals are normally marked with the letter T
or TX (T = "transmitter").
• Put the crystal holder (1) back into the transmitter.
• Switch the receiver system off and remove the crys-
tal (4) from the plug-in socket in the receiver.
• The suitable crystal for the receiver has to be marked
with the same channel number as the transmitter
crystal. In addition it is marked with the code R or RX
(R = receiver).
• Insert the receiver crystal (5) with the suitable fre-
quency for the transmitter into the receiver.
• Switch on the transmitter and afterwards the receiver
and check the functioning of the system.
