Supplied Screws
Installing the Antenna
1. Turn the antenna clockwise until it is secured.
zDo not hold or twist the upper part of the
antenna when installing or removing it. To
do so may break the conductors inside the
antenna.
zDo not key the transmit without installing the
antenna. The transmitter components may
be damaged.
zWhen using an antenna other than the
one supplied, or connecting to an external
antenna, ensure that the SWR is adjusted to
1.5 or lower.
Attaching the Belt Clip
1. Attach the belt clip on the back of transceiver
using the supplied screws (two).
zBe sure to use the supplied screws when
attaching the belt clip. If any other screws
are used, the belt clip cannot be secured
firmly to the battery pack and the transceiver
may drop off together with the battery pack;
the transceiver and battery pack may fall off,
causing injury, breakage and other damage.
zUse a hand strap which can withstand the
weight of the transceiver. If the hand strap is
not strong enough, the it may break and the
transceiver may fall, causing injury, breakage
and other difficulty.
Installing the Battery Pack
Referring to the figure at the right, insert
the battery pack into the seals of the battery
compartment on the back of the transceiver.
2. Push the battery pack in until the battery latch
