Be certain that all station wiring is properly insu-
lated so as to prevent short-circuits which could dam-
age this transceiver and/or accessories connected to
it. Be sure to protect power cables from damage due
to abrasion by ensuring 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 insulation.
Never spill liquids into this transceiver, and do not
drop sharp metallic objects into the transceiver enclo-
sure. Electrical shock may result when you attempt to
remove the object.
Unsupervised children should be kept away from
any electrical apparatus such as the MARK-V FT-
1000MP Field transceiver and its accessories.

NTENNA
Always install antennas such that they can never
come in contact with outdoor power lines in the event
of a catastrophic antenna support or power line sup-
port structure failure. An adequate safety margin is
usually provided by separating power lines from the
antenna and its support structure [1.5 times the height
of the support] plus [the length of any antenna or guy
wires attached to the support] plus [the height of the
power line support pole].
Ground the antenna support structure adequately,
so as to dissipate energy absorbed during a lightning
strike. Install appropriate lightning arrestors in the an-
tenna lead-in and rotator cable (if used) according to
the arrestor's instructions.
In the event of an approaching electrical storm, dis-
connect all antenna lead-in, rotator control, and power
cables completely from the station, but only if the
storm is not immediately in your area. Do not allow
disconnected cables to touch the case of your MARK-
V FT-1000MP Field transceiver or accessories, as light-
ning can easily jump from the cable to the circuitry of
your transceiver via the case, causing irreparable dam-
age. If a lightning storm is in progress in your immedi-
ate area, do not attempt to disconnect the cables, as
you could be killed instantly should lightning strike your
antenna, tower, or a nearby power line.
If a vertical antenna is used, be certain that humans
and/or pets or farm animals are kept away both from
the radiating element (to prevent electrical shock and
RF exposure danger) and the ground system (in the
event of an electrical storm). The buried radials of a
ground-mounted vertical antenna can carry lethal volt-
ages outward from the center of the antenna in the
event of a direct lightning strike.

LECTROMAGNETIC
This transceiver is capable of power output in ex-
cess of 50 Watts, so customers in the United States
may be required to demonstrate compliance with Fed-
eral Communications Commission (FCC) regulations
concerning maximum permissible exposure to radio
frequency energy. Compliance is based on the actual
power output used, feedline loss, antenna type and
height, and other factors which can only be evaluated
as a system. Information regarding these regulations
may be available from your Dealer, your local radio
club, from the FCC directly (press releases and other
information can be found on the FCC's site on the World
Wide Web at <http://www.fcc.gov>), or from the Ameri-
can Radio Relay League, Inc. (225 Main St., Newington
CT 06111 or < http://www.arrl.org >).
Remember to re-evaluate your station's compliance
with these regulations during portable operations such
as Field Day or special-event stations.
Regarding electromagnetic compatibility: if this
transceiver is used with, or in the vicinity of, a com-
puter or computer-driven accessories, you may need
to experiment with grounding and/or Radio Frequency
Interference (RFI) suppression devices (such as fer-
rite cores) to minimize interference to your communi-
cations caused by energy from the computer. Com-
puter-generated RFI is usually a result of inadequate
shielding of the computer's cabinet or I/O and periph-
eral connections. While computer equipment may
"comply" with RF emission standards, this does not
ensure that sensitive amateur radio receivers will not
experience interference from the device!
Be certain to use only shielded cables for TNC-to-
Transceiver connections. You may need to install AC
line filters on the power cord(s) of the suspected equip-
ment, and decoupling ferrite toroidal chokes may be
required on interconnecting patch/data cables. As a last
resort, you can try installing additional shielding within
the computer's case, using appropriate conductive
mesh or conductive shielding tape. Especially check
"RF holes" where plastic is used for cabinet front pan-
els.
For further information, consult amateur radio ref-
erence guides and publications relating to RFI suppres-
sion techniques.
