groups, you need to set different channels for the devices
(including both transmitters and receivers) of different
groups.
2, When you need to add more receivers to a group, and
the channel of these added receivers is not the same as
Transmitter (Handheld Type)
01
that of the devices of the group, you need to set the
channel of these added receivers to be the same as that of
the group. ( The channel of the transmitter and the
receivers in a group must be the same，or the receivers
can not receive the signal from the transmitter)
(2)The way of channel setting:

indicator light flashes 4 times, and the battery level has only
20% left if the indicator light flashes only once.
Attention:
When the transmitters and receivers are not used for a long
time, please charge them once every 3 months, so that the
batteries can be protected. (There is lithium battery inside
the device, if it was not used or charged for a long time, the
battery would be damaged.) In one word, make sure that
the batteries inside the transmitters and receivers always
have power.
User manual of Charging case
1.Power supply：AC 90V--250V
2.When it is going to be charged, take the foam out, and
keep the cover open in case it gets hot .
3.When it is charging, the battery level on the display
screen of the transmitters shows going up, and it stops

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
This 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 Retekess 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 the 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://www.who.int/en/
Local Government Regulations
When 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 requirements. Exposure
awareness can be facilitated by the use of a product label directing
users to specific user awareness information. Your Retekess radio has
a RF Exposure Product Label. Also, your Retekess user manual, or
separate safety booklet includes information and operating instructions
required to control your RF exposure and to satisfy compliance
requirements.
Radio License (if appropriate)
Governments keep the radios in classification, business radios operate
on radio frequencies that are regulated by the local radio management
departments (FCC, ISED, OFCOM, ANFR, BFTK, Bundesnetzagentur...
).To transmit on these frequencies, you are required to have a license
issued by them. The detailed classification and the use of your radios,
please contact the local government radio management departments.
Use of this radio outside the country where it was intended to be
distributed is subject to government regulations and may be prohibited
Warnings
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.
