10  MAINTENANCE
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will
prevent damage to the transceiver.
• Keep the microphone connected or the jack covered at all times to prevent
corrosion of electrical contacts;
• Never key the microphone unless an antenna or suitable dummy load is
connected to the transceiver.
• Ensure that the supply voltage to the transceiver does not exceed 16 VDC
or fall below 11 VDC.
• Use only STANDARD HORIZON-approved accessories and replacement
parts.
In the unlikely event of serious problems, please contact your Dealer or our
repair facility. Address and phone numbers for this facility, as well as warranty
information, are contained in section 12 WARRANTY.

when connected to
power supply.
Popping or whining
noise from the speaker
while engine runs.
Sound is not emitted
from the internal or ex-
ternal speaker.
Sound is not emitted
from the PA speaker.
Receiving station re-
port low transmit
power, even with trans-
ceiver set to HI power.
“HI BATTERY” or “LO
BATTERY” message is
appeared when the
power is turned on.
“PA ERROR” or “FOG
ERROR” message is
shown when the PA/
FOG mode is acti-
vated.
Your position is not dis-
played.
PROBABLE CAUSE
No DC voltage to the
transceiver, or blown
fuse.
Reversed power
wires.
Engine noise.
Accessory cable.
Accessory cable.
Antenna.
The power supply
voltage is too high or
too low.
Accessory cable.
Accessory cable.
Setting of the GPS
navigation receiver.
REMEDY
a. Check the 12VDC battery connections and
the fuse.
b. The VOL/PWR knob needs to be pressed
and held to turn the radio on.
Check the power cable for DC voltage, or re-
place the fuse (6A 250V).
Make sure the red wire is connected to the posi-
tive (+) battery post, and the black wire is con-
nected to the negative (-) battery post. If the
fuse still blows, contact your Dealer.
Reroute the DC power cables away from the
engine. Add noise suppressor on power cable.
Change to resistive spark plug wires and/or add
an alternator whine filter.
Check the connections of the accessory cable
(Short Circuit the External speaker cable
WHITE/SHIELD).
Check the accessory cable connection (Short
Circuit the PA speaker cable RED/SHIELD).
Have the antenna checked or test the trans-
ceiver with another antenna. If the problem per-
sists, contact your Dealer for servicing.
Confirm that the connected power supply volt-
age is not 17 volts or lower than 10 volts. Con-
firm that the generator has not malfunctioned.
Check the accessory cable connection (Short
Circuit the PA speaker cable RED/SHIELD).
Check the accessory cable connection.
Some GPS use the battery ground line for
NMEA connection.
Check the output signal format of the GPS navi-
gation receiver. This radio requires NMEA0183
format with GLL sentence as an output signal.
If the GPS has a baud rate setting make sure
to select 4800 and parity to NONE.

11.  CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments for
U.S.A. and International use. Below are listed some data about the charts.
1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s
Vessel Traffic System.
2. Alpha channel numbers, that is, channel numbers followed by the letter A
(such as Channel 07A) are simplex channels on the U.S.A. or Canadian
channel assignments whose counterparts in the International assignments
are duplex channels. International channels do not use “alpha” numbers. If
you call the Coast Guard on Channel 16, they will sometimes ask you to
“go to channel 22 Alpha.” This is a channel assigned to U.S.A, and Cana-
dian Coast Guards for handling distress and other calls. If your radio is set
for International operation you will go to Channel 22 instead of 22A, and
will not be able to communicate with the Coast Guard. To use Channel 22A,
your radio must be set for USA or Canada operation, usually by a U/I/C
(USA/International/Canada) control or combination of controls. Channel 22
(without an “A”) is an International duplex channel for port operations.
Some radios indicate an “A” adjacent to the alpha channels on the display;
on others “alpha” is not indicated but the proper channel is selected based
on the U/I/C setting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge
operators on intercoastal waterways and rivers. It is also used by marine
vessels in the vicinity of these bridges for navigation and for communicat-
ing with the bridge operators. Note that a limit of 1 Watt is specified for
these channels. See page 27 for additional information.
4. The S/D column on the chart indicates either S (simplex) or D (duplex).
Simplex means transmitting and receiving on the same frequency. Only
one party at a time can talk, unlike a telephone. Be sure to say “over” and
release your microphone push-to-talk switch at the end of each transmis-
sion. Duplex operation involves the use of one frequency for transmitting
and a separate frequency for receiving. On channels specified as duplex
on the charts, correct mode of operation is established automatically by
your radio when you select a channel; you cannot change the mode. And
you still must release the push-to-talk switch after each transmission in
order to listen to the radio.
5. Channels normally used by recreational boaters are those that include the
term “non-commercial” in the Channel Use column of the chart. Some of
these are shared with other users and some are used only in certain geo-
graphic regions.

6. Marine vessels equipped with VHF radios are required to monitor
Channel 16.
