location of four holes where the fixing screws is to go into;
LCaution: Be careful to not drill through the mounting surface.
3. Remove the bracket, drill four holes smaller than the screw diameter, then
re-place the mounting bracket on the surface aligning the drilled holes;
4. Insert the four fixing screws and secure the bracket to mounting surface
using the supplied bolts, spring washers, plain washers and nuts;
LCaution: if you can not reach behind the mounting surface to attach the nut on
the bolts, use the supplied self-tapping screws to fasten the bracket.
5. Insert the four fixing screws and fasten them with a Philip screw driver with
attention not to screw too tightly;
6. Mount the base station onto the bracket with notice of the matching of the
protuberances on the both inner side of the bracket and the pits on the two
sides of the base station (the selectable pits on the sides of the radio allow
you adjust the direction of the radio face to satisfy your easy-to-read-and-
use, 150for each rotation and totally 450tolerance);
7. Attach the supplied mounting knobs from the two sides of the bracket to
fixing the base station securely.
LCaution: KEEP the radio and handset at least 1 meter away from any magnetic
devices such as compass on your vessel.
