Safety Precautions
Before proceeding with installation of the VX-1700 trans-
ceiver, please read and observe all safety and operating
instructions. Consult with qualified installation or service
personnel should any questions arise regarding these im-
portant safety tips.
Power Connections
The power connector for the VX-1700 must only be con-
nected to a DC source providing 13.8 Volts DC (±15 %),
and capable of at least 20 Amperes of current. Do not con-
nect this apparatus to any other DC voltage, and never
connect the DC power cable to an AC source of any kind.
Always observe proper polarity when making DC connec-
tions. Our Limited Warranty does not cover damage caused
by improper power connections.
Note that other manufacturers may use the same type of
DC power connector as does your VX-1700 transceiver,
but the wiring configuration of the other manufacturer’s
plug may be different from that specified for your trans-
ceiver. Serious damage can be caused if improper DC con-
nections are made; consult with a qualified service techni-
cian when in doubt.
Grounding for Electrical Safety
Connect the rear panel ground lug to a good earth ground.
For best performance, such a ground should consist of one
or more ground rods 2.6 m (8 feet) long, connected to the
transceiver via a low-inductance cable such as a heavy
braided wire (the shield from surplus/discarded RG-213
type cable is ideal). The lead-in cable should be as short
as possible.
Do not use gas lines as a ground connection!
Electrical Shock Prevention
Be certain that all station wiring is properly insulated so
as to prevent short-circuits which could damage this trans-
ceiver and/or accessories connected to it. Be sure to pro-
tect power cables from damage due to abrasion by ensur-
ing that they cannot be walked upon nor crushed under
rolling chairs, etc. Never route power cables near sharp
metallic edges which might cut through protective insula-
tion.
Never spill liquids into this transceiver, and do not drop
metallic objects into the transceiver enclosure. Electrical
shock may result when you attempt to remove the object.
Unsupervised children should be kept away from any elec-
trical apparatus such as the VX-1700 Transceiver and its
accessories.
INSTALLATION
Antenna Precautions
Always locate antennas such that they can never come in
contact with outdoor power lines in the event of a cata-
strophic antenna support or power line support structure
failure. Ground the support structure adequately, so as to
dissipate energy absorbed during a lightning strike. Install
appropriate lightning arrestors in the antenna lead-in and
rotator cable (if used) according to the arrestor’s instruc-
tions.
In the event of an approaching electrical storm, discon-
nect all antenna lead-in, rotator cables, and power cables
completely from your station if the storm is not immedi-
ately in your area. Do not allow disconnected cables to
touch the case of your VX-1700 transceiver or accesso-
ries, as lightning can easily jump from the cable to the
circuitry of your transceiver via the case, causing irrepa-
rable damage. If a lightning storm is in progress in your
immediate area, do not attempt to disconnect the cables,
as you could be killed instantly if lightning should strike
your antenna structure or a nearby power line.
If a vertical antenna is utilized, be certain that humans and/
or pets and farm animals are kept away both from the radi-
ating element (to prevent electrical shock and RF expo-
sure danger) and the ground system, in the event of an
electrical storm. The buried radials of a ground-mounted
vertical antenna can carry lethal voltages outward from
the center of the antenna in the event of a direct lightning
strike.
Heat and Ventilation
To ensure long life of the components, be certain to pro-
vide adequate ventilation around the cabinet of the VX-
1700. The cooling system of the transceiver must be free
to draw cool air in from the bottom of the transceiver and
expel warm air from the rear of the transceiver.
Do not install the transceiver on top of another heat-gen-
erating device (such as a linear amplifier), and do not place
equipment, books, or papers on top of the transceiver. Place
the transceiver on a hard, flat, stable surface. Avoid heat-
ing vents and window locations that could expose the trans-
ceiver to excessive direct sunlight, especially in hot cli-
mates.
