First, unplug the RF connector coming from the transmitter circuit board from the standard transmitter modu-
le of your radio system. This connector is then plugged into connection socket 1 (INPUT) of the switch.
Connect the modules with the included cables as shown in the fi gure above. The sockets are also polarised;
note the small noses on the side. Never use force - the plugs should engage easily and fully. 35 MHz mo-
dules must be connected to socket 2, socket 3 is provided for 2.4 GHz modules (or socket 4 for Weatronic
modules). If two 2.4 GHz modules are used, one must be connected to socket 2.
NOTE:
the sockets 3 and 4 are contacted, when using a Weatronic module socket 3 must remain empty. The
second 2.4 GHz module is then connected to socket 2. In addition, the Weatronic cable should be secured in
the transmitter case (eg. by a cable tie), so that the plug can not be released accidentally.
The RF switch has a safety switch, ie you have to pull the lever to move the switch. The red LED lits when
module 1 (socket 2) is activated, the green LED lits when module 2 (socket 3 or 4) is active.
