RF Energy Exposure Compliance
Your radio is designed and tested to comply with a number of national and international standards
and guidelines (listed below) regarding human exposure to radio frequency electromagnetic
energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at operating duty factors of up to 50%
transmitting and is authorized by the FCC for occupational use only. In terms of measuring RF
energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF
energy only while it is transmitting (during talking), not when it is receiving (listening) or in
standby mode.
Your radio complies with the following of RF energy exposure standards and guidelines
● United States Federal Communications Commission, Code of Federal Regulations; 47CFR
part 2 sub-part J
● American National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992
● Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Safety Information
The following safety precautions shall always be observed during operation, service and
repair of this equipment.
z This equipment shall be serviced by qualified technicians only.
z Do not modify the radio for any reason.
z Use only HYT supplied or approved antenna.
z Gain of antenna must not exceed 3.5dBi for VHF or 5.5dBi for UHF.
z Mobile antenna Installation: Install the mobile antenna at least 100cm (34 inches)
away from your body, in accordance with the requirements of the antenna
manufacturer/supplier.
z Transmit only when people inside and outside the vehicle are at least the minimum
distance away from a properly installed, externally mounted antenna.
z Mobile antenna substitution: Don’t substitute HYT supplied or approved antenna, or
excessive radio frequency radiation will result. Please contact your dealer or the
manufacturer for further instructions.
z Please make sure there’s no stress on the antenna joint during transportation or
installation.
z To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio
in any area where posted notices instruct you to do so. Hospital or health facilities
may be using equipment that is sensitive to external RF energy.
z For vehicles with an air bag, do not place a radio in the area over an air bag or in the
air bag deployment area.
z Turn off your radio prior to entering any area with explosive and flammable materials.
z Do not expose the radio to direct sunlight over a long time, nor place it close to
heating source.
▇ Operation Guidelines
For vehicles equipped with electronic anti-skid braking systems, electronic ignition
systems or electronic fuel injection systems, interferences may occur during radio
transmission. If the foregoing electronic equipments are installed on your vehicle, please
contact your dealer for further assistance to make sure that radio transmission will not
interfere with these equipments.
For radio installation in vehicles fueled by LP gas with LP gas container within interior of
the vehicles, the following precautions are recommended for personal safety.
1. Any space containing radio equipment shall be isolated by a seal from the space in
which the LP gas container and its fittings are located.
2. Remote (outside) fitting connections shall be used.
3. Good ventilation is required for the container space.
▇ Installation Guidelines
z Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof
or trunk lid if the minimum safe distance is observed.
z Do not mount the mobile radio overhead or on a sidewall unless you take special
precautions.
z If the mobile radio is not properly installed, road shock could bump the radio loose,
and the falling radio could, in some circumstances, cause serious injury to the driver
or a passenger. In case of vehicle accidents, even when properly installed, the radio
could break loose and become a dangerous projectile.

▇Scan Type
1. Single Zone Scan
The radio scans all the channels added into the scan list on the current zone.
2. Multi Zone Scan
Multiple zones added into a multi scan list can be scanned. All channels within the zones added into the
scan list can be scanned.
▇Scan Start
1. Add one or more non-priority channels into the scan list.
2. Press the programmed Channel Scan key to initiate scan from the current channel (please scan the
channels one by one in accordance with the list). The LCD displays SCAN (-SCAN- for multi zone
scan) and the icon.
▇Scan Cease

1. Press the programmed Channel Scan key and cease the scanning, so that the radio may exit the
scan mode.
2. Activate the Monitor function.
3. The radio receives the carriers which satisfy radio unmute condition
▇Scan Resume
If the scanning pauses on an active channel, it will resume according to the scan resume mode. The
scan resume mode can be programmed by your dealer with Carrier operated scan or Time operated
scan.
1. Time Operated Scan
Scanning remains on an active channel for a programmed time period (programmable by your dealer).
Once the timer expires, the radio will begin scanning other channels even if the active channel is still
busy.
2. Carrier operated scan
If carriers are detected during the scan sequence, scanning will remain on the active channel until there
is no activity.
▇Dual Priority Scan
If dual priority channels are programmed by your dealer, the radio will check the dual priority channels for
activity regularly on the non-priority channels. If carriers are detected on a priority channel, the radio will
immediately switch to this active priority channel.
LCD displays the “P" icon to indicate the Priority Channel 1, the “P. ” icon to indicate the Priority Channel
2, and the “P:” icon to indicate the channel is programmed with Priority Channel 1 and 2 simultaneously.
▇Scan Add/Delete

microphone is in an off hook position or not. If the feature is disabled, CTCSS/CDCSS signaling is
disabled with an off-hook palm microphone is in the off hook condition.
Time-out Timer (TOT)
▇Time-out Timer (TOT)
This feature is able to prevent any single user from using a channel for an extended period, and to
protect the radio against damage caused by prolonged transmission.
If the preset time (off, 15~1200 seconds) expires, the radio will automatically terminate transmission and
keep beeping. Beeps will not stop unless the PTT key is released.
The TOT default is 180 seconds, which can fully satisfy common users. Any change should be permitted
by professional technicians.
▇TOT Pre-alert
With a TOT Pre-alert timer, the radio can generate pre-alert tone at the programmed time (1~10 seconds
before the TOT timer expires).

programmable), and the radio will return to its original channel.
Frequency Reverse
If communications between radios are disrupted due to a long distance away from the repeater, the
Frequency Reverse function can be applied to re-establish communications with other radios. When this
function is activated, the Tx and Rx frequencies will be reversed. The preset CTCSS/CDCSS encoding
and decoding processes will also be reversed.
Press the Frequency Reverse key (programmable function key) to toggle the Frequency Reverse
function ON or OFF.
Enabled Disabled
Talk Around
If the Talk Around feature is enabled, the radio will transmit at its Rx frequency, and the CTCSS/CDCSS
