CHANNEL CHECK MODULE 40 MHZ


Supplementary module for the HFM3 RF module (PROFI mc), the HFM-4 RF module
(ROYAL evo), and PiCOline and COCKPIT MM transmitters. The module is installed by
opening the RF module case or the transmitter itself, and the CHANNEL-CHECK module
is simply plugged into the sockets provided.

The system is ready for use once you have
fitted the appropriate receiver crystal (same channel as the transmitter crystal!).
