5-4 Raychart 425 Chartplotter
When planning the location for the unit, consider finding a convenient
pathway for running the interconnecting cable between the GPS
Receiver and the display unit or to the rest of an integrated system. Ideally
the cable should be run such that it is hidden from view and, if possible, be
in a direct path to the point of connection. It is important to keep the cable
separated from other shipboard cables as far as possible to prevent
interference pick-up.
Note: Mounting on the mast of a sailboat is not recommended.
Surface Mounting
Refer to Figure 5-2:
1. Select a suitable area which allows access to the underside of the
mounting surface for fixing and, using the template supplied in this
document, carefully drill the two 6mm (0.25in) fixing holes marked.
2. If the cable is to pass through the mounting surface drill the 6mm
(0.25in) or 19mm (0.75in) centre hole depending on whether the plug
is to pass through the surface or not.
If the cable is to exit from the side of the GPS Receiver above the
mounting surface, remove the two plastic tabs (1) obstructing the
cable channel.
Note: Failure to remove the plastic tabs from within the cable channel
could result in cable damage.
3. Screw the supplied brass studs (2) into the underside of the GPS
Receiver.
4. Stick the supplied gasket (3) to the mounting surface ensuring that the
holes match and pass the cable through the centre hole or the cable
exit channel.
5. Carefully position the GPS Receiver, passing the studs through the
holes in the mounting surface and secure to the mounting surface
using the thumb nuts provided (4).
