GMR 600/1200 Series Installation Instructions 3
Installing the Mounting Studs and Seals
1. Remove the hatch on the front of pedestal by loosening the screw and lifting the hatch off of the hinges as shown in Figure 1.
2. Use a 5 mm Allen wrench, to install the M10 x 71 mounting studs (Figure 2) in the pedestal matching the hole pattern that was selected.
Tighten the mounting studs until they bottom out in the pedestal. Do not overtighten the studs to avoid damaging the pedestal. The mounting
studs have a thread-locking patch applied at the factory.
Optional: Apply moisture-inhibitive grease or paste to the four studs prior to installation.
3. Install the seals onto the pedestal (Figure 3).

Mounting the Radar
Mount the radar with either end pointed toward the bow. Ensure it is mounted along the Bow-Stern Axis line indicated on the GMR
400/600/1200 Series Mounting Template. If the end with the hatch is pointed toward the bow, the Front of Boat Offset setting on the chartplotter
must be set to 180° (Figure 4). To adjust the Front of Boat Offset on the chartplotter, see page 7.
To mount the radar:
1. (Skip to step two if you are using a pre-drilled Garmin compatible Furuno
®
or Raymarine
®
mount.) Determine a suitable mounting location
and tape the Mounting Template in place. The Mounting Template has two hole patterns: Option A and Option B. Determine the most
appropriate patterns from the two patterns available on the Mounting Template (Option A or Option B). Use a

four mounting holes.
2. Hoist the radar into position using the supplied strap. Position the strap over the ends of the antenna mount as shown in Figure 5. Ensure
that you position the strap as close to the radar as possible.
