Pressing [C>] increases the channel number and pressing [<B] decreases it.
§ Making a Call
1 Select the desired channel.
2 Press the Side1 key (Programmed function Squelch off) to determine whether or not the current channel is being
used.
• If the channel is busy, wait until it becomes free.

• For best results, hold the microphone approximately 3 to 4 cm (1 1/2 inches) from your lips.
4 Release the PTT switch to receive.
AUXILIARY FEATURES
§ Time-out Timer (TOT)
The TOT is used to automatically inhibit transmission after a specified time elapse. If the PTT switch is held down for
longer than specified time, the transceiver will stop transmitting and a tone will sound. Release the PTT switch, then
press it again to continue transmitting.
Radio FRequency eneRgy SaFety inFoRmation
This KENWOOD transceiver has been tested and complies with the standards listed below, in regards
to Radio Frequency (RF) energy and electromagnetic energy (EME) generated by the transceiver.
• FCC RF exposure limits for
Occupational Use Only
. RF Exposure limits adopted by the FCC are generally
based on recommendations from the National Council on Radiation Protection and Measurements, & the
American National Standards Institute.
• FCC OET Bulletin 65 Edition 97-01 Supplement C
• American National Standards Institute (C95.1 – 1992)
• American National Standards Institute (C95.3 – 1992)
This KENWOOD transceiver generates RF EME while transmitting. RF EME (Radio Frequency Electric &
Magnetic Energy) has the potential to cause slight thermal, or heating effects to any part of your body less
than the recommended distance from this radio transmitter’s antenna. RF energy exposure is determined
primarily by the distance to and the power of the transmitting device. In general, RF exposure is minimized
when the lowest possible power is used or transmission time is kept to the minimum required for consistent
communications, and the greatest distance possible from the antenna to the body is maintained. The
transceiver has been designed for and is classied for
Occupational Use Only
. Occupational/ controlled
exposure limits are applicable to situations in which persons are exposed to RF energy as a consequence
of their employment, and such persons have been made aware of the potential for exposure and can
exercise control over their exposure. This means you can use the transceiver only if you are aware of
the potential hazards of operating a transceiver and are familiar in ways to minimize these hazards. This
transceiver is not intended for use by the general public in uncontrolled environments. Uncontrolled
environment exposure limits are applicable to situations in which the general public may be exposed to RF
energy, or in which the persons who are exposed as a consequence of their employment may not be fully
aware of the potential for exposure or cannot exercise control over their exposure.
The following list provides you with the information required to ensure that you are aware of RF
exposure and of how to operate this transceiver so that the FCC RF exposure limitations are not
exceeded.
• While transmitting (holding the PTT switch or speaking with VOX enabled), always keep the antenna
and the radio at least 3 cm (1 3/16 inches) from your body or face, as well as from any bystanders. A
LED on the top of the radio shows red when the transmitter is operating in both PTT and VOX modes.
• Do not transmit for more than 50% of the total transceiver use time; transmitting over 50% of the total use
time may exceed the limits in accordance to the FCC RF exposure requirements. Nominal transceiver
operation is 5% transmission time, 5% reception time, and 90% stand-by time.
• Use only the specied antenna for this transceiver; this may be either the antenna provided with the
transceiver or another antenna authorized by KENWOOD.
Use only KENWOOD authorized accessories (antennas, battery packs, belt clips, Speaker/ Mics
or headsets etc.): When worn on the body, always place the radio in a KENWOOD recommended
clip or carrying case meant for this product. The use of other than recommended or approved
body- worn accessories may result in RF exposure levels which exceed the FCC’s occupational/
controlled environment RF exposure limits.
To ensure that your exposure to RF EME is within the FCC limits for occupational use, you must
observe and adhere to the above points.
Electromagnetic Interference Compatibility
Electronic devices are susceptible to electromagnetic interference (EMI) if they are not adequately
shielded or designed for electromagnetic compatibility. Because this transceiver generates RF
energy, it can cause interference to such equipment.
• Turn OFF your transceiver where signs are posted to do so. Hospitals and health care facilities use
equipment that is sensitive to electromagnetic radiation.
• Turn OFF your transceiver while on board an aircraft when so instructed. Use of the transceiver must
be in accordance with airline regulations and/or crew instructions.
