6 FCC NOTICE
NOTICE
Unauthorized changes or modifications to this equipment may void com-
pliance with FCC Rules. Any change or modification must be approved
in writing by STANDARD HORIZON.
NOTICE
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to ra-
dio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be de-
termined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
NOTE
The MATRIX AIS
GX2100
does not require a special marine VHF an-
tenna to receive AIS transmissions. The MATRIX AIS does not transmit
AIS signals, it is NOT recommended to use an antenna dedicated for
AIS operation.
What is the range for AIS receivers?
Since AIS uses similar frequencies as a marine VHF radio, it has similar radio
reception capabilities - which are basically line of sight. This means that the
higher the VHF antenna is mounted, the greater the reception area will be.
Reception from Class A vessels that are 20 or even 30 miles away on open
water is not uncommon as their antennas are mounted high off the water.
Class B transponders use lower power for transmissions; therefore you can
expect Class B vessels to be acquired when they are 5 to 10 miles away.
