Introduction
The Multi-Light module has been specially developed for RC modelling applications, and provides
a means of fitting out various types of model with a wide variety of lighting signals, such as
navigation lights, flashers, panoramic lamps and searchlights, as realistically as possible.
All the lighting functions are permanently installed in the module, and cannot be altered.
The functions are selected by moving the corresponding DIP switches and connecting the lamps to
the appropriate terminals.
We have carried out thorough research on the different lighting signals for vehicles, boats and
aircraft, and the signals are programmed in a logical arrangement in the module.
This Multi-Light module can be used for a very wide variety of model types.
Safety Notes
Please read right through these operating instructions before using the module for the first
time, and store them in a safe place for possible future reference.
The integrated circuits employed in the Multi-Light module are delicate, and vulnerable to
damage from electro-static charge. For this reason please avoid touching these components
unless you have first "discharged" yourself, e.g. by grasping a central-heating radiator or other
earthed device.
The Multi-Light module may only be operated on the stated power supply voltages.
All wiring and connections should only be carried out with the circuit disconnected from the
power source.
The Multi-Light module is not suitable for use by young persons under fourteen years of age.
Modes of operation:
There are three different modes of operation:
Boat
Ground vehicle
Model aircraft
The mode of operation is selected by determining the model type using the DIP switches S1.1 -
S1.3.
"Boat" mode:
In this mode of operation the lights are controlled using a Nautic switch module fitted to the
transmitter. The Nautic signal is connected to the Prop #1 input (X4/1). The red LED on the module
flashes to indicate that the Light module is picking up the Nautic signal correctly.
For model boats with a Voith-Schneider power system, the direction of travel can be detected via
the Prop #2 (X4/2) and Prop #3 (X4/3) inputs; in this case the lighting system is automatically
switched over when the boat is towing or assisting.
If a servo is switched on (Prop #5 and #6 output), this automatically moves to and fro between the
right and left end-points.
The frequency of the flickering light can be altered by adjusting the trimmer P1.
The speed of the servos can be altered by adjusting the trimmer P2.
"Vehicle" mode:
In this mode of operation the lights are controlled using a Nautic switch module fitted to the
transmitter. The Nautic signal is connected to the Prop #1 (X4/1) input. The red LED on the module
flashes to indicate that the Light module is picking up the Nautic signal correctly.
