2. Do not attempt to disassemble the battery pack housing.
Battery storage
1. Battery has the phenomenon of self-discharge, therefore,if the
battery is not in use for a long time, please be fully charged first
before storage, this is to void battery damage due to excessive
self-discharge.
2. After a period of storage, battery needs to be charger, In order
to avoid excessive battery from the battery capacity is reduced.
Battery storage is recommended after 6 months battery charge.
3. Please note that the temperature and humidity of store
battery. Keep the battery in a cool, dry conditions room to avoid
battery self-discharge
Install and Remove Accessories

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR
PORTABLE WALKIE TALKIE
This two-way radio uses electromagnetic energy in the radio
frequency (RF) spectrum to provide com munications between two
or more users over a dis tance. 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://www.who.int/en/
Local Government Regulations

of employment, the Local Government Regulations requires users
to be fully aware of and able to cont rol 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 Retevis two-way radio has a RF
Exposure Product Label. Also, your Retevis user manual, or
separate safety booklet includes information and operating
instructions required to control your RF exposure and to satisfy
compliance requirements.

RF Exposure Information
• DO NOT operate the radio without a proper antenna attached, as

18
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
requirements to beexceeded.
• During transmissions, your radio generates RF energy that can
possibly cause interference with other devices or systems. To avoid
such interfere-nce, turn off the radio in areas where signs are
posted to do so.
• DO NOT operate the transmitter in areas that are sensitive to
electromagnetic 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
configurations. RF exposure compliance is limited to the specific
belt-clip and accessory configurations as docum-ented 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 desig-ned for and
classified 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
