Installation – Control Unit
7.1
Mounting possibilities
Mounting is carried out by first fixing the backplate, after which the
Control Unit can simply be slid over and clicked into place. There is
a template on page 31 to help you mount the unit.
To avoid theft, the control unit can be removed when leaving the boat
or during the off-season simply by pressing the spring and lifting it
off the backplate
7.2
Power supply
The Control Unit is supplied with +12V DC from the SPARC-bus
interface.
If there is a short circuit or fire, it is important that your VHF remain
operational. We therefore recommend that the power cable be
connected directly to the ship’s battery.
