INSTALLATION
Choose a location for your radio that is free from direct water spray, Rain and
direct sunlight. If the radio is mounted in a location subject to extreme vibration
or pounding when running, a suitable s
hock mount must be used. Allow
sufficient room behind your radio for cables to be installed and do not install the
unit too close to the compass. The “Compass Safe Distance” should be 12 to
15 inches.

5
15 inches.
3.1 Mounting Bracket
The mounting bracket may beused for base or gimbals type overhead
mounting.
Secure the bracket to the mounting surface by using at least four Screws.
3.2 Antenna Connection
Use VHF marine antenna, which has the 50 ohm impedance and the correct
termination. It should
be mounted as high as possible for maximum range.
Connect the antenna connector to the corresponding connector on the back of
the radio, using a 50 ohm coaxial cable with a PL 259 connector. Do not cut or
shorten your antenna lead wire, as it will effect t
he VSWR and could damage
your unit. LT manufactures an complete line of VHF antennas that are perfectly
matched and tuned to the LT2001. IMPORTANT: Do not attempt to transmit
without an antenna (or with an improper antenna) connected. This may cause
permanent damage to your radio.
3.3 PowerConnection
This unit operates from a 12 volt. negative ground electrical system. Do not
attempt to use it in a positive ground system. The DC power cable supplied is
used to make the necessary DC connection to your b
oat battery. Choose a
point which is able to handle at least 6 amps. Your best location would be the
switched side of your ignition switch. If you must extend the power leads, keep
wiring as short as possible, since long wires can reduce the transmitter
pe
rformance. Use #10 wire size for up to 10feet and size #8 for up to 25 feet.
Be sure to connect the red (fused) lead to the positive terminal and the black to
the (-
) or ground. The radio is equipped with “reverse polarity protection.” This
will automatica
lly blow the fuse, thus protecting the unit from harm if the
polarity should be reversed during installation. If the fuse should blow,
immediately turn off the radio and re-
check your battery connections. Always
replace the fuse with one having the same ra
ting. Replacement with a higher
rated fuse could cause damage to the radio.
3.4 Microphone Connection
Microphone supplied with the radio on the front panel.
3.5 External Speaker Connection
The radio can be used with an external speaker system by ma
king use of the
EXT SP jack on the rear panel. Connect the external speaker designed of this
purpose.

6.5
Simplex/Duplex Channel Use
A. A simplex channel is used for ship-to-ship communication. The transmit
And receive frequencies are the same.
Example: CH 22A 157.000 MHz, transmit & receive (USA mode)
B. A duplex channel is a public correspondence, ship-to-coast channel
Which
is mainly used by Marine Telephone Operators. A duplex channel
cannot be used for ship-to-
ship communication because the transmit and
receive frequencies are not the same. Example CH 24 157.200 MHz transmit
and 161.800 MHz receive, (USA mode.)
NOTE:Al
l channels are factory programmed in accordance with FCC (USA) and IC
(Canada), and International regulations. Mode of operation cannot be altered from
simplex to duplex or vice-versa.
