SWITCH ACTIVE
- LED ON (LIT)
SWITCH INACTIVE
- LED OFF (UNLIT)
IF LED IS PERMANENTLY ‘ON’ AFTER THE
INITIAL POWER-UP PULSES THEN EITHER
NO RC SIGNAL IS PRESENT
(TRANSMITTER TURNED OFF) OR YOU
HAVE THE WRONG TRANSMISSION
******IMPORTANT****
Always fit a Fuse between your batteries and the Load.
If there is a wiring short circuit or a defect, there is
normally enough current in your batteries to set fire to
your precious Model.
Fuses, Diodes, Resistors and Suppression Kits are

Short Leg is the Cathode.
Cathode is connected to the Negative
side of the batteries
With most of our kits it is unnecessary
to use a resistor in the circuit as they
are already built in on the Module.
CHECK THE DATASHEET FIRST!
The Resistor can be placed in either Leg of the LED
