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.
Hold the thick base
of the antenna
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.
