Safety: It s mportant that the operator s aware of, and understands, hazards common to the operaton of any transcever. recaUtioNs • Do not charge the transcever and battery pack when they are wet. • Ensure that there are no metallc tems located between the transcever and the battery pack. • Do not use optons not specfed by Kenwood. • If the de-cast chasss or other transcever part s damaged, do not touch the damaged parts. • If a headset or headphone s connected to the transcever, reduce the transcever volume. Pay attenton to the volume level when turnng the squelch off. • Do not place the mcrophone cable around your neck whle near machnery that may catch the cable. • Do not place the transcever on unstable surfaces. • Ensure that the end of the antenna does not touch your eyes. • When the transcever s used for transmsson for many hours, the radator and chasss wll become hot.

When the arbag nflates, the transcever may be ejected and strke the drver or passengers. • Do not transmt whle touchng the antenna termnal or f any metallc parts are exposed from the antenna coverng. Transmttng at such a tme may result n a hgh-frequency burn. • If an abnormal odor or smoke s detected comng from the transcever, swtch the transcever power off mmedately, remove the battery pack from the transcever, and contact your Kenwood dealer. • Use of the transcever whle you are drvng may be aganst traffc laws. Please check and observe the vehcle regulatons n your area. • Do not expose the transcever to extremely hot or cold condtons. • Do not carry the battery pack (or battery case) wth metal objects, as they may short the battery termnals. • When operatng the transcever n areas where the ar s dry, t s easy to buld up an electrc charge (statc electrcty). When usng a earphone accessory n such condtons, t s possble for the transcever to send an electrc shock through the earphone and to your ear. We recommend you use only a speaker/ mcrophone n these condtons, to avod electrc shocks.

Page 26: Operating.through.repeaters
OPERATING THROUGH REPEATERS Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the communications industry. Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically located on mountain tops or other elevated locations. -
Page 27: R Epeater A Ccess
epeAter cceSS Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split). In addition, some repeaters must receive a tone from the transceiver in order to gain access to the repeater. For details, consult your local repeater reference. -
