Charging the Battery Pack
1.The battery is not charged in the factory,please charge the battery
under the environmental temperature 5—40℃ before using.
2.After purchasing or long-term storage(more than two months),
charging the battery for the first time can not reach its saturation
capacity,repeat charge/discharge for twice or three times to make
battery capacity achieve the best state.
3.Before charging,please power off the transceiver,using the
transceiver during charging may affect correct charging.
4.If the battery has been charged fully,please do not charge it again,
otherwise the service life of the battery may be shorten or may be
damaged.
5.If the service time is significantly reduced even after completely
correct charging,the battery can not be used any more,please
replace a new battery.

1.Short press keys to adjust the volume.
2.Short press key to switch to channel mode,then short press
keys to adjust the channels.
3.PTT: press this button whenever you wish to talk with the user of the
other radio.
Menu Opeartion
It is convenient for the user to search for calls from other channels.
When “Side Key 2” in the software is programmed to the scanning
function,long press key for two seconds to enter into the scanning
mode,the transceiver will start to scan with the current channel;
Operate it again to exit.

Keyboard Lockout
Long press key to lock all buttons,operate it again to unlock.
Power Display
Short press power key to display the current battery level.
Monitoring
Long press key for two seconds to enter into the monitor mode,
release it to exit.
VOX
This function can be voice activated so the user doesn’t have to press
the PTT key.
When “VOX level” in the software is selected,short press key twice
to enter into the VOX mode,then short press key or key to turn
on/off the VOX.
Time Out Timer(TOT)
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 key and
the transceiver will return to standby.
Busy Channel Lockout
The function can prevent interference from other transceivers using
the same channel.
Battery Power Saving
If there is no signal or operation,the radio will reduce its power
consumption.The battery power-saving function activates when the
channel is unoccupied or has not been in operation.
Low Battery Warning
If the battery power falls to the predetermined value during
transmission,the transceiver will give out a voice prompt,please
charge in time.
Scrambling
It is a voice encryption mode which is different from sub audio.
.
Companding
It is a function setting which prevents the inter-channel interference.

CTCSS/DCS
The transceiver has 50 CTCSS and 208 DCS,also non-standard
subaudio can be programmed!
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.

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR
PORTABLE TWO-WAY RADIOS
Local Government Regulations
Before using this radio, read this guide which
contains important operating instructions for safe
usage and rf energy awareness and control for
compliance with applicable standards and
regulations.
This two-way radio uses electromagnetic energy in the radio
frequency (RF) spectrum to provide communications between
two or more users over a distance. RF energy, which when used
improperly, can cause biological damage.
All Retevis two-way radios are designed, manufactured, and
tested to ensure they meet government-established RF exposure
levels. In addition, manufacturers also recommend specific
operating instructions to users of two-way radios. These
instructions are important because they inform users about RF
energy exposure and provide simple procedures on how to
control it.
Please refer to the following websites for more information on
what RF energy exposure is and how to control your exposure to
assure compliance with established RF exposure limits:http://ww-
w.who.int/en/
When two-way radios are used as a consequence of employment,
the Local Government Regulations requires users to be fully
aware of and able to control their exposure to meet occupational
ATTENTION!
