PRECAUTIONS
TO USER:
Thank you for purchasing this Class B DSC VHF marine
transceiver. You will find the professional and human oriented
design of the transceiver during use. Please read all
instructions carefully and completely before using the
transceiver.
This transceiver adopts advanced waterproof technology and
has excellent waterproof performance.
Never use the distress call when your ship or
personnel is not in an emergency.
Do not use or place the transceiver in hot, humid and
dusty areas.
The working voltage for the transceiver is 13.8V DC.
If the power supply is 24V DC, please use a power
converter (24V convert to 13.8V), or the transceiver
won’t work.
Never directly connect to 220V AC power supply, this
will ruin the transceiver. If an abnormal odor or
smoke is detected coming from the transceiver, turn
off the power immediately.
Do not transmit before connecting the antenna, it will
ruin the transceiver.

Using the Supplied Mounting Bracket
Supplied Accessories
The universal mounting bracket supplied with your transceiver allows
overhead or dashboard mounting.
1. Fix the mounting bracket to overhead or dashboard with the
screws and mount the transceiver to the mounting bracket with the
knob bolts.
2. Adjust the transceiver so that the face of the transceiver is at 90°to
your line of sight when operating it and tighten the knob bolts so
that the transceiver is securely mounted.
Notice: You may use a spongy cushion between the transceiver
and mounting bracket to reduce the vibration.

1. Cut a hole into the instrument panel (or wherever you plan to
mount the transceiver).
2. Slide the transceiver through the hole as shown below.
3. Attach the clamps on both sides of the transceiver with 2 supplied
bolts.
4. Tighten the end bolts on the clamps so that the clamps press
firmly against the inside of the instrument control panel.
Please connect an antenna before transmitting. Select the antenna with
the corresponding frequency and install on the ANT antenna base. Use
the antenna and coaxial feeder with the same natural impedance 50Ω.
Notice: Do not transmit before connecting the antenna, it will ruin the
transceiver.

When connecting the external speaker, GPS, DC power supply,
computer and navigation device by the rear panel cable end, cover the
connectors and cables with rubber vulcanzing tape as below, to
prevent water seeping into the transceiver.
Red - Positive(+), Black - Negative(-).The output voltage of the
connected DC power supply must be 13.8V. Do not connect the
transceiver to the 24V storage battery. If the current supplied to the
transceiver is insufficient, the display may darken during transmission
or the transmitting output power may drop significantly.
One fuse is installed in the supplied DC power cable. If a fuse blows
or the transceiver stops functioning, track down the source of the
problem first, then replace the damaged fuse with a new, rated one.
Notice: Please power off transceiver before replacing the fuse, the
required fuse is DC15A.
Connect this terminal to a vessel ground to prevent electrical shocks
and interference from other equipment occurring. Use a PH M3×6
mm screw (not supplied).
Through the rear panel cable, this transceiver can connect GPS input
signals from GPS receivers, and can also output GPS signals to
other devices.
Used to output position data received from other ships to a
computer or navigation device.
Transceiver output signal conforms to NMEA0183 version 3.01
sentence formatters DSC, DSE compatible .
Used for ship position indication.
A NMEA0183 ver. 2.0 or 3.01 (sentence formatters RMC, GGA,
GNS, GLL) compatible GPS receiver is required.
Connect a cloning cable.
