● Emergency Alarm
The purpose of the TOT is to prevent any single person from
using a channel for an extended period of time. An alarm will
sound if the transmission continues beyond the set time. The
transceiver will stop transmission if this occurs. To stop the
alarm, release the PTT switch and the transceiver will return to
standby.
● VOX

● Companding
It is a function setting which prevents the inter-channel
interference.
● CDCSS Mode
It is valid only when you program the CDCSS on the channels.
This function has two selections: "normal signaling" and "special
signaling". Normal Signaling refers to the CDCSS codes on the
channels is ordinary codes, we can talk to each other with the
same CDCSS; Special Signaling refers to the CDCSS codes on
the channels is special processed codes. When the transceivers
in one company are programmed the same frequency with the
same CDCSS and special signaling, they can avoid the signal
interferences from the other companies’ transceivers.
● CTCSS/DCS
The transceiver has 50 CTCSS and 208 DCS, also nonstandard
subaudio can be programmed! CTCSS function is used to avoid
mutual interference among various users and also to avoid
hearing irrelevant calls and interference signals. CDCSS is a
further development of the continuous tone-coded squelch system
or CTCSS that uses a slow-speed,binary data stream passed as
sub-audible data along with the transmission. It adds a tone into
your transmission at a certain frequency.

RF Exposure Information
• DO NOT operate the radio without a proper antenna attached, as
this may damage the radio and may also cause you to exceed RF
exposure limits. A proper antenna is the antenna supplied with this
radio by the manufacturer or an antenna specifically authorized by
the manufacturer for use with this radio, and the antenna gain shall
not exceed the specified gain by the manufacturer declared.
• DO NOT transmit for more than 50% of total radio use time, more
than 50% of the time can cause RF exposure compliance requirem-
ents to be exceeded.
• During transmissions, your radio generates RF energy that can
10

possibly cause interference with other devices or systems. To
avoid such interference, turn off the radio in areas where signs are
posted to do so.
• DO NOT operate the transmitter in areas that are sensitive to elect-
romagnetic radiation such as hospitals, aircraft, and blasting sites.
• Portable Device, this transmitter may operate with the antenna(s)
documented in this filing in Push-to-Talk and body-worn configurat-
ions. RF exposure compliance is limited to the specific belt-clip and
accessory configurations as documented in this filing and the
separation distance between user and the device or its antenna
shall be at least 2.5 cm.
• Mobile Device, during operation, the separation distance between
user and the antenna subjects to actual regulations, this separation
distance will ensure that there is sufficient distance from a properly
installed externally-mounted antenna to satisfy the RF exposure
requirements.
• Occupational/Controlled Radio, this radio is designed for and classi-
fied as “Occupational/Controlled Use Only”, meaning it must be used
only during the course of employment by individuals aware of the
hazards, and the ways to minimize such hazards; NOT intended for

• Transmit no more than the rated duty factor of 50% of the time. To
Transmit (Talk), push the Push to Talk (PTT) button. To receive calls
(listen), release the PTT button. Transmitting 50% of the time, or less,
is important because the radio generates measurable RFenergy
exposure only when transmitting in terms of measuring for standards
compliance.
• Transmit only when people outside the vehicle are at least the reco-
mmended minimum lateral distance away from a properly installed
according to installation instructions, externally mounted antenna.
• When operating in front of the face, worn on the body, always place
the radio in a Retevis approved clip, holder, holster, case, or body
harness for this product. Using approved body-worn accessories is
important because the use of Non-Retevis approved accessories
may result in exposure levels, which exceed the IEEE/ICNIRP RF
exposure limits.
Hand-held Mode
• Hold the radio in a vertical position with the microphone
(and other parts of the radio including the antenna) at
least 2.5 cm (one inch) away from the nose or lips. The
antenna should be kept away from the eyes. Keeping
the radio at a proper distance is important as RF
exposure decreases with increasing distance from the antenna.
Phone Mode
• When placing or receiving a phone call, hold your radio product as
you would a wireless telephone. Speak directly into the microphone.
