*Excluding the cable connection zone. The cover reads Galaxy 303 – Galaxy 305; every page inside is headed Galaxy 303 and describes a 2-channel unit.

  • In the box: 2-channel radio control (transmitter and receiver already paired), transmitter with 1.5V AAA alkaline batteries fitted, adhesive labels for windlass or thruster function, support kit for the transmitter and 4 screws 3.5x13mm for RX and TX, instructions.

Installation & Wiring

  • Always disconnect the battery before installation.
  • Mount the receiver well away from large metal masses and electric motors or the windlass.
  • Behind metal bulkheads or other obstacles to the radio signal, fit the optional external antenna (not included).
  • Stick the label for the function you use (windlass or thruster) on the transmitter, and check everything works after wiring.
Receiver terminal Connection
1 (A2) − battery
2 (A1) + battery via switch
3 (C1) Common, via a 3 A fuse
4 (B2) OUT1
5 (B3) OUT2

Each relay output has a common contact: connect the common to the positive or negative pole according to the polarity of the load (the windlass control box). Protect it with a 3 A fuse against short circuit.

Operation & Pairing

Using It

  • Press ON for about 2 seconds: the LED flashes while idle and stays on while a button is pressed.
  • Releasing a button stops the manoeuvre. Switching Up to Down (or Left to Right) has a fixed 1.5 sec. delay.
  • The transmitter switches off 120 seconds after the last command.
  • On power-up the receiver's green LINE LED comes on; a yellow LED lights for each output when its button is pressed.

Pairing a New Transmitter

  1. Power the receiver: the green LINE LED comes on and, 1 sec. later, the red programming LED, which stays on for about 15 sec. While it is on, turn the new transmitter on with ON.
  2. Hold UP (left button).
  3. Press PROG on the receiver.
  4. Release UP.
  5. The LED blinks four times and goes out: the transmitter is stored. Check it works.
  • The receiver stores up to 5 transmitters; a sixth replaces the first one stored.
  • To add a transmitter to a unit already in use: power the receiver, press and hold PROG until the red LED comes on, release, then follow the steps above.

Batteries & External Antenna

  • Batteries: undo the 8 screws on the back, fit 1.5V AAA alkaline batteries only, observe polarity (reversed batteries do no damage but the unit will not work), refit the cover and the 8 screws.
  • External antenna: drill a 5 mm hole in the lower part of the receiver, right of the cable entry (12.5 and 15 from the edges on the drawing); remove the internal antenna from the terminal board; connect the cable shield to the right contact and the signal wire to the left; close the receiver and fix the antenna with the flat washer and nut supplied.

Warranty: 3 years.
