PRESIDENT LTD 715
The PRESIDENT LTD 715 VHP marine radio transceiver has been

5
designed to give you a rugged, reliable instrument that will provide you
with years of trouble-free service.
With proper care and maintenance, your PRESIDENT LTD 715 will
outlast your present vessel and serve you well on-board several more.
The full features and flexibility designed into this quality transceiver will
prevent it from becoming obsolete regardless of changes in craft or
geographic locations.
The technical excellence of the PRESIDENT LTD 715 is demonstrated
by the multiplicity of uses for which it has been found acceptable by the
U.S. Federal Communications Commission. The PRESIDENT LTD 715
is acceptable for compulsoiy use on “party boats," for use on vessels
subject to the Great Lakes Radio Agreement or bridge-to-bridge
requirements, for general pleasure and commercial vessels, and certain
land stations in marine service.
The PRESIDENT LTD 715 is of all solid state design with conservatively
rated rugged components and materials compatible with the marine
environment. The transceiver utilizes a number of gaskets, sealing rings,
waterproof membranes, and other sealants to effect a splashproof
housing for protection of the electronics. The unit may be mounted in
any number of convenient locations on your vessel by utilizing the
universal mounting bracket.
You are encouraged to thoroughly read the rest of this Operating Guide
to acquaint yourself with the characteristics and operation of your
transceiver so that you can contribute to the longevity of your investment.
Be sure to complete the Product Registration Card at the back of this
Guide, cut it out and mail it. You also need to complete the enclosed
Warranty Registration Card and mail it.

INSTALLATION
CAUTION: The LTD 715 will operate only with nominal 12 volt
negative ground battery systems.
It is important to carefully determine the most suitable location for your
LTD 715 on your vessel. Electrical, mechanical, and environmental
considerations must all be taken into account. You must select the
optimum relationship among these considerations.
ENGINE NOISE SUPPRESSION
Interference from the impulse noise generated by the electrical systems
of engines is sometimes a problem with radios. The LTD 715 has been
designed to be essentially impervious to ignition impulse noise and
alternator noise. However, in some installations it may be necessary to
lake measures to further reduce the effect of noise interference. Ail DC
battery wires, antenna lead, and accessory cables should be routed away
from the engine and engine compartment, and from power cabling
carrying particularly high currents.
Keep in mind the flexibility designed into the LTD 715 so that you can
most convenientiy use your radio. Features which should be considered
are:
1. The universal mounting bracket may be installed on either the lop or
bottom of a sheif, on a bulkhead, or for overhead mounting.
2. The REMOTE speaker jack can be used with an auxiiiary speaker.
3. All connections are “piug-in" type for easy removal of the radio.
CHOOSING A LOCATION
Some important factors to consider in seiecting the iocation for your
LTD 715 .
1. Seiect a location that is free from spray and splash.
2. Keep the battery leads as short as possible. Direct connection to
the battery is most desirable. If direct connection cannot be made
with the supplied power lead, any extension should be made with
ff 10 AWG wire. Long extensions should use larger gauge wire.
3. Keep the antenna lead as short as possible. Long anteniia leads
can cause substantial loss of performance for botn receiving and
transmitting.
4. Locate your antenna as high as possible and clear from metal
objects. The reliable range of coverage is a direct function of
antenna height.
5. Select a location that does not allow the radio to be subjected to
direct sunlight (including that coming through windows).
6. Select a location that allows free air flow around the heal sink on the
rear of the radio.
7. Select a location well away from the ship’s compass. Auxiliary
speakers also should be located away from the compass.
In severe cases of impulse noise interference, it may be necessary to
install a noise suppression kit. Contact your PRESIDENT Dealer for
more information.
ANTENNA CONSIDERATIONS
A variety of antennas is available from a number of quality suppliers, it is
recomrnended you draw upon the advice of your PRESIDENT Dealer in
determining a suitable antenna for your vessel and range requirements.
In general, communication range is increased by using a high-gain
antenna placed as high as possible above the water line. Antennas
should be located away from metal objects. Antennas should not have
excessively long coaxial feed cables.
INSTALLING THE LTD 715
After you have carefully considered the various factors affecting your
choice of location, position the radio (with the bracket, microphone,
power cord, antenna and any auxiliary cables installed) into the selected
location to assure there is no interference with the surrounding items.
Mark the location of the mounting bracket. Remove the bracket from the
radio and use it as a template to mark the holes to be drilled for the
mounting hardware. Drill the holes and mount the bracket with hardware
compatible with the material of the mounting surface.
Connect the red wire of the supplied power cord to the positive (+) battery
supply. Connect the black wire of the power cord to ground. The power
cord is equipped with a fuse to protect the radio. Use only a Six (6)
AMPERE fast blow fuse for replacement. Connect the power cord to the
keyed connector on the power "pigtail" (See page 6).
Connect the antenna and all other auxiliary cables and accessories.
Install the radio in the mounting bracket and connect ail cables and
accessories to the appropriate jacks and connectors.

MARITIME RADIO SERVICES OPERATION
You are required to comply with the Rules and Regulations as set forth
by the Federal Communications Commission. A complete set of FCC
Marine Radio Rules may be purchased from the US Government Printing
Office by requesting “Volume IV of the FCC Rules,” Among the more
significant rules are:
You may not make transmitter tuning adjustments unless you are
the holder of a valid first or second class commercial license issued
by the FCC. Please request the assistance of your PRESIDENT
Marine Dealer and your nearest FCC Field Office if you need other
than a Ship’s Station License.

CARE AND MAINTENANCE
__________
Your LTD 715 is a precision piece of electronic equipment and you
should treat it accordingly. Due to the rugged design, very little
maintenance is required. However, a few precautions should be
observed:
• If your radio has been accidentally subjected to spray or splash, you
should immediately wipe it down with a soft cloth dampened with fresh
water.
• If the antenna has been damaged, you should not transmit except in
case of emergency. A defective antenna may cause damage to your
radio.
• You are responsible for the continued FCC technical compliance of
your radio.
• You are urged to arrange for periodic performance checks with your
PRESIDENT Marine Dealer.
1. You must obtain a Ship’s Station License by making application to
the FCC on FCC Form 506. An Interim Ship’s Station License may
be obtained by personal appearance at your local FCC Field Office.
The Ship's Station License must be posted at the station location.
2. A Restricted Radiotelephone Operator Permit (or higher grade
license) must also be obtained from the FCC in order to legally
operate your transmitter in international waters. Application is to be
made on FCC Form 753, An interim permit is automatically granted
upon submission of your application.
3. You must keep a current copy of the appropriate FCC Rules.
4. You must maintain a log book in which you record all calls and full
transmitter maintenance records.
5. Your transmitter must be verified, by an appropriately licensed
technician, to be in compliance with FCC requirements. This has
been done at the factory for your LTD 715. A signed Certificate of
Compliance card is included with your radio and should be kept with
your log book.
