Active Speaker Mounting Considerations
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.
-
You can use the included 10 m (32 ft.) extension cable to connect the active speaker to the VHF radio. You must select a mounting location for the speaker where you can connect the extension cable to the active speaker and to the GHS 11 STATION 1 port on the VHF radio. If needed, additional extension cables are available from your Garmin® dealer.
