MoTeC Beacon Transmitter 11
• The beacon transmitter will operate when the LED is orange, however the
transmitted power is reduced which reduces the operating range.
Power
The unit should be powered from a 12V rechargeable battery. A small sealed
lead acid battery is recommended as it can be easily charged and will operate
the transmitter for several days. A capacity of 10Ahr or greater is
recommended. The battery may also be used as a weight at the base of the
mounting system for stability.
Connect the red wire to battery positive, and the black wire to battery
negative.
Note that the unit requires at least 10.5 V for proper operation.
It is recommended that the battery be charged regularly to ensure good
battery life.
See Appendix G - Transmitter Wiring for connection details.
