Step  Install 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. Using a 5 mm Allen wrench, 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 because this may cause damage to 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). Figure 1 Figure 2 Figure 3 Step  Mount the Scanner The scanner can be mounted with either end pointed toward the bow as long as it is mounted along the Bow-Stern Axis line indicated on the Mounting Template. If the end with the hatch is pointed toward the bow, the Bearing Offset in the chartplotter must be set to 180° (Figure 4). To mount the scanner: 1. 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 which pattern fits your mount or better suits your mounting location. Using a Center Punch, indent the center of each mounting hole. Using a 13 mm (1/2") bit, drill the four mounting holes. (This step is not necessary if you are using a pre-drilled Garmin compatible Furuno® or Raymarine® mount). 2. Hoist the scanner into position using the supplied strap. Position the strap over the ends of the antenna mount as shown in Figure 5. Make sure that the strap is positioned as close to the scanner as possible. 3. Fasten the scanner to the mounting surface using the M10 hex nuts, spring washers, and flat washers in the order shown in Figure 6. The M10 nuts should be torqued to 130 in.lbs (11 ft.lbs) (1.5 kgf.m).

Step
Install 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.
Using a 5 mm Allen wrench, 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 because this may cause damage to 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.

Step
Mount the Scanner
The scanner can be mounted with either end pointed toward the bow as long as it is mounted along the Bow-Stern Axis line indicated on the
Mounting Template. If the end with the hatch is pointed toward the bow, the Bearing Offset in the chartplotter must be set to 180° (Figure 4).
To mount the scanner:
1.
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 which pattern fits your mount or better suits your mounting location. Using a Center Punch, indent the center
of each mounting hole. Using a 13 mm (1/2") bit, drill the four mounting holes. (This step is not necessary if you are using a pre-drilled
Garmin compatible Furuno
®
or Raymarine
®
mount).
2.
Hoist the scanner into position using the supplied strap. Position the strap over the ends of the antenna mount as shown in Figure 5.
Make sure that the strap is positioned as close to the scanner as possible.
3.
Fasten the scanner to the mounting surface using the M10 hex nuts, spring washers, and flat washers in the order shown in Figure 6.
The M10 nuts should be torqued to 130 in.lbs (11 ft.lbs) (1.5 kgf.m).
