The mounted push-button caps can be replaced with push-button caps with different symbols as required. This is necessary, for example, if the transmitter is to be used for a jib crane (replace push-button caps with the symbol for forward and backward crane travel with push-button caps with the symbol for slewing to the right and left) or if push-button caps with individual symbols are to be used.

The transmitter does not require disassembly to exchange the caps.

   Fully press down the actuator and hold it.

   Using a blunt instrument, pry out the white catches of the detent ring at the top, bottom, left and right on the sleeve.

●   The push-button cap now only lies loosely on top of the transmitter.

   Take off the push-button cap.

   Turn the actuator of the new push-button cap so that the undercut lies precisely between two catches.

   Attach the new push-button cap. The undercut ensures that the cap fits in only a single position.

   Press in the sleeve around the circumference until the detent ring latches.
