Safety Instructions
Safety Instructions
Warning
(1) Be careful not to let any metal chips or the like get in connectors. Metal chips can
short-circuit connector pins, possibly causing a fire or damage. Insert connectors straight.
Inserting them at a slant can short-circuit connector pins, possibly causing a fire or damage.
(2) Do not disassemble or alter this antenna unless you are a qualified repair technician.
Disassembling or altering it may cause a fire or electrical shocks.
(3) This antenna radiates electromagnetic waves.
(4) They are very weak and pose no safety problem. However, do not keep touching the
antenna for a long time (five minutes or longer) unless you are trying to adjust its direction.
Caution
(1) Install this antenna in a stable, vibration-free place. Otherwise, it may drop or fall over,
possibly resulting in injury.
(2) When moving the antenna from one place to another, be careful not to drop it. Otherwise, an
accident or injury may occur.
(3) When installing the antenna, be careful not to drop it, its dust caps or tools. Otherwise, an
accident may occur.
(4) Select a sufficiently strong place when installing the antenna. If it is installed in a place not
sufficiently strong, it may fall down, possibly resulting in an accident.
The mark on the electrical and electronic products only applies to the current European
Union Member States.

Installing the Antenna
Wrap self bonding tape
around the connections
as a watertight measure.
Wrap self bonding tape
around the connections
as a watertight measure.
When wrapping the tape,
pull it so that it becomes
half as wide as its
original width and paste
each turn of the tape in
such a way that they
overlap with one another
by half the width. (To
ensure watertightness,
wrap the tape up to the
root of each connector
firmly.)
Moreover, wrap PVC
tape around the self
bonding tape.
If no cable is attached to
a connector, wrap the
connector with self
bonding tape and PVC
tape to make it watertight
in the same manner as for
connectors with a cable
attached.

Installing the Antenna
(2) Caution
Observe the following caution in order to avoid accidents.
• When installing this antenna, be careful not to drop it and its components.
Caution for Installation
(a) Before starting installation work after unpacking, check the components and their
quantity with the parts list.
(b) Work with care. When carrying or assembling the antenna and related components,
be careful not to cause damage to them.
(c) Handling
<1> Do not place any stuff on the components of the antenna kit.
<2> When carrying the antenna kit, be careful not cause damage to the covers and
connectors.
Do not move the antenna from one place to another with cables attached to its
connectors.
<3> Two or more workers should be involved in the antenna installation work. When
installing the antenna, work with utmost care, and use rope to keep the antenna and its
components from dropping.
<4> When installing the antenna, be sure to observe (2), “Antenna installation procedure”.
<5> The component end surfaces have sharp edges. Be very careful when handling the
components.
