PRECAUTIONS
Please read all safety and operating instructions before
using this transceiver. For best results, be aware of all
warnings on the transceiver and follow the provided
operating instructions. Retain these safety and
operating instructions for future reference.
1 Power Sources
Connect this transceiver only to the power source
described in the operating instructions or as marked
on the transceiver itself.
2 Power Cable Protection
Route all power cables safely. Ensure the power
cables can neither be walked upon nor pinched by
items placed near or against the cables. Pay
particular attention to locations near AC receptacles,
AC extension bars and points of entry to the
transceiver.
3 Electrical Shocks
Take care not to drop objects or spill liquids into the
transceiver through enclosure openings. Metal
objects, such as hairpins or needles, inserted into
the transceiver may contact voltages resulting in
serious electrical shocks. Never permit children to
insert any objects into this transceiver.
4 Grounding and Polarization
Do not attempt to defeat methods used for
grounding and electrical polarization in the
transceiver, particularly involving the input power
cable.
5 Outdoor Antenna Grounding
Adequately ground all outdoor antennas used with
this transceiver using approved methods.
Grounding helps protect against voltage surges
caused by lightning. It also reduces the chance of a
build-up of static charges.
6 Power Lines
Minimum recommended distance for an outdoor
antenna from power lines is one and one-half times
the vertical height of the associated antenna support
structure. This distance allows adequate clearance
from the power lines if the support structure should
fail for any reason.
7 Ventilation
Locate the transceiver so as not to interfere with its
ventilation. Do not place books or other equipment
on the transceiver that may impede the free
movement of air. Allow a minimum of 4 inches
(10 cm) between the rear of the transceiver and the
wall or operating desk shelf.
8 Water and Moisture
Do not use the transceiver near water or sources of
moisture. For example, avoid use near bathtubs,
sinks, swimming pools, and in damp basements and
attics.
9 Abnormal Odors
The presence of an unusual odor or smoke is often a
sign of trouble. Immediately turn the power OFF and
remove the power cable. Contact a dealer or the
nearest Service Center for advice.
10 Heat
Locate the transceiver away from heat sources such
as radiators, stoves, amplifiers or other devices that
produce substantial amounts of heat.
11 Cleaning
Do not use volatile solvents such as alcohol, paint
thinner, gasoline or benzene to clean the cabinet.
Use a clean cloth with warm water or a mild
detergent.
12 Periods of Inactivity
Disconnect the input power cable from the power
source when the transceiver is not used for long
periods of time.
13 Servicing
Remove the transceiver’s enclosure only to do
accessory installations described by this manual or
accessory manuals. Follow provided instructions
carefully to avoid electrical shocks. If unfamiliar with
this type of work, seek assistance from an
experienced individual, or have a professional
technician do the task.
14 Damage Requiring Service
Enlist the services of qualified personnel in the
following cases:
a) The power supply or plug is damaged.
b) Objects have fallen or liquid has spilled into the
transceiver.
c) The transceiver has been exposed to rain.
d) The transceiver is operating abnormally or
performance has degraded seriously.
e) The transceiver has been dropped or the
enclosure damaged.
