12. Change of Crystal

In order to avoid a double channel assignment 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 recom-
mended for the use of your remote control system by the supplier.
To change the crystal, proceed as follows:
• Disconnect the flight battery from the helicopter and switch off the transmitter.
• Pull the holder of the transmitter crystal from the rear side of the transmitter casing (see figure 11,
pos. 2).
• Take the transmitter crystal out of its plastic holder. Insert the replacement crystal with a different
channel in the same frequency band.
Please make sure that you place the right crystal in the holder. Transmitter crystals are normally
marked with the letter T or TX (T = "transmitter"). Put the crystal holder back into the transmitter.
• Remove the crystal of the receiver (see fig. 14, pos. 3) from the electronics module.
• The suitable crystal for the receiver has to be marked with the same channel number as the trans-
mitter crystal. In addition it is marked with the letter code R or RX (R = receiver).
• Insert the replacement crystal with the suitable frequency for the transmitter into the receiver.
• Switch the transmitter on and then the receiver and check the functioning of the system.
