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, it is recommended to 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. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.
The included active speaker is optional, and is not required
when installing the VHF 315 device. When selecting a mounting
location for the active speaker, observe these considerations.
• To avoid interference with a magnetic compass, do not install
the active speaker closer than 50 cm (19.6 in.) to a compass.
• You must install the active speaker inline with a GHS
™
11
handset.
• You must install the active speaker within 1.2 m (48 in.) of the
location you want to connect the GHS 11 handset.
• You must install the active speaker connected to the primary
handset (connected to the GHS 11 STATION 1 port) in the
wheelhouse or an adjacent room, in accordance with FCC
law.
