Mounting Considerations

NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The temperature range for this device is listed in the product specifications. Extended exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may cause device failure. Extreme-temperature-induced damage and related consequences are not covered by the warranty.

• You must mount the device in a location where it will not be submerged.
• You must mount the device in a location with adequate ventilation where it will not be exposed to extreme temperatures.
• If possible, you should mount the device horizontally, with the top of the device facing upward.
• If you must mount the device vertically, you should orient it so the connectors do not point upward. This helps avoid potential water retention around the connectors.

Antenna Mounting and EME Exposure

WARNING Radio operators with cardiac pacemakers, life-support machines, or electrical medical equipment should not be exposed to excessive radio-frequency (RF) fields, because the RF field may interfere with the function of their medical equipment.
CAUTION This device generates and radiates radio frequency (RF) electromagnetic energy (EME). Failure to observe these guidelines may expose people to RF radiation absorption exceeding the maximum permissible exposure (MPE).

Garmin® declares a MPE radius of 2.48 m (97.64 in.) for this system, which was determined using 25 W output to an omni-directional, 6 dBi gain antenna. The antenna should be installed to maintain a distance of 2.48 m (97.64 in.) between the antenna and all people.

Mounting the Device

NOTICE
If you are mounting the device in fiberglass, when drilling the pilot holes, use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.

Before you mount the device, you must select a mounting location and determine the mounting hardware needed for the surface.

NOTE: Mounting hardware is included with the device, but it may not be suitable for the mounting surface.

1. Place the device in the mounting location and mark the location of the pilot holes.
2. Using a bit appropriate for the surface and the mounting hardware, drill a pilot hole for one corner of the device.
3. Loosely fasten the device to the surface with one corner and examine the other three pilot-hole marks.
4. Mark new pilot-hole locations if necessary.
5. Remove the device from the mounting surface.
6. Drill the appropriate pilot holes for the other three marks.
7. Secure the device to the mounting location.

Active Speaker Mounting Considerations

NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The temperature range for this device is listed in the product specifications. Extended exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may cause device failure.
