RT57 Wireless business Calling Device
Instruction Manual
Product Overview
Wireless Business Beeper is a kind of communication device that can achieve sample
wireless calling service. For example, in an enterprise or public institution, a leader need
look for his or her secretary, driver or the manager of another department and things like
that. At present, there are plenty of beepers in the market that cannot allow to make a
voice call. A superior need page his or her employee to come and tell things face to face.
Given the fact that there is a lack of this kind of beeper in the market, our company launch
a new model RT57 - Wireless business Calling Device.

Main Technical Parameters
Technical Features
1. There is no need to wire or change current decoration. Reception is stable and perform-
ance reliable. With up-to-date digital encoding and decoding technology, every system
owns its unique code that ensures there is no error between calling system.
2. Two-way communication but ordinary business beepers only establish communication
between master station and extended set. Our new model is designed to satisfy
prevailing market demand that an extension could not only communicate freely to master
station but also to other extensions. A phone set as the terminal could be turned into the
master for the group call as well as an extension for the reception of signals from other
extension terminal. It is able to be used for one-to-one calling and also one-to-many
communications.
3. It could be connected to a wakietalkie for voice call.
4. With good audio quality and long range, it is ideal for a big occasion. It makes no
difference to desk telephone without wires.

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR PORTABLE WALKIE
TALKIE
This walkie talkie uses electromagnetic energy in the radio frequency (RF) spectrum to
provide communications between two or more users over a distance. It uses radio
frequency (RF) energy or radio waves to send and receive calls. RF energy is one form
of electromagnetic energy. Other forms include, but are not limited to, sunlight and x-rays.
RF energy, however, should not be confused with these other forms of electromagnetic
energy, which when used improperly, can cause biological damage. Very high levels of
x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to
develop standards for safe exposure to RF energy. These standards provide recommen-
ded levels of RF exposure for both workers and the general public. These recommended
RF exposure levels include substantial margins of protection.
All Retevis walkie talkie 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 walkie talkie. 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 walkie talkie 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 Retevis walkie talkie 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.
Radio License
Governments keep the radios in classification, most of the classified walkie-talkie need to
get local government License, and operation is allowed. The detailed classification and
the use of your two radios, please contact the local government radio management
departments. For the following specified classification: the USA FRS, Australian CB, the
individual license is not required.
ATTENTION!
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.

subject to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may cause
undesired operation of the device.
In terms of measuring RF energy for compliance with these exposure guidelines, your
radio generates measurable RF energy only while it is transmitting (during talking), not
when it is receiving (listening) or in standby mode.
Note: The approved batteries, supplied with this radio, are rated for a 5-5-90 duty factor
(5% talk-5% listen-90% standby) even though this radio complies with FCC
occupational exposure limits and may operate at duty factors of up to 50% talk.
RF energy exposure standards and guidelines (if appropriate)
Your Retevis walkie talkie complies with the following RF energy exposure standards and
guidelines:
• United States Federal Communications Commission (FCC), Code of Federal Regulations;
47 CFR part 2 sub-part J.
• American National Standards Institute (ANSI) / Institute of Electrical & Electronic
Engineers (IEEE) C95. 1-2005
• IEEE Std. 1528:2013 and KDB447498, Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
• Institute of Electrical and Electronic Engineers (IEEE) C95.3-2002
• International Commission on Non-Ionizing Radiation Protection (ICNIRP)
• Ministry of Health (Canada) Safety Code 6 & Industry Canada RSS-102.
• International Electrotechnical Com-mission IEC62209-2:2010]
RF Exposure Compliance and Control Guidelines and Operating
Instructions
To control your exposure and ensure compliance with the occupational / controlled
environment exposure limits, always adhere to the following procedures.
Guidelines:
• User awareness instructions should accompany the device when transferred to other
users.
• Do not use this device if the operational requirements described herein are not met.
Operating Instructions:
• 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. Transmi-
tting 50% of the time, or less, is important because the radio generates measurable RF
energy exposure only when transmitting in terms of measuring for standards compliance.
• Transmit only when people outside the vehicle are at least the recommended 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 accessor-
ies may result in exposure levels, which exceed the IEEE/ICNIRP occupational/controlled
environment RF exposure limits.
• If you are not using a body worn accessory and are not using the radio in the intended
use position, in front of the face or at the body in the PTT mode or alongside of the head
in the phone mode, then ensure the antenna and the radio are kept 2.5 cm (one inch)
from the body when transmitting. Keeping the radio at a proper distance is important
because RF exposures decrease with increasing distance from the antenna.
Hand-held Mode
• Hold the radio in a vertical position with the microphone (and other
parts of the radio including the antenna) atleast 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.
Electromagnetic Interference/Compatibility
Note: Nearly every electronic device is susceptible to electromagnetic interference (EMI)
if inadequately shielded, designed, or otherwise configured for electromagnetic
compatibility.
Avoid Burns
Small Parts. Not for children under 3 years.
Turn off your radio power in the following conditions:
• Turn off your radio before removing (installing) a battery or accessory or
when charging battery.
• Turn off your radio when you are in a potentially hazardous environments:
Near electrical blasting caps, in a blasting area, in explosive atmospheres
(inflammable gas, dust particles, metallic powders, grain powders, etc.).
• Turn off your radio while taking on fuel or while parked at gasoline service
stations.
To avoid electromagnetic interference and/or compatibility conflicts
• Turn off your radio in any facility where posted notices instruct you to do
so, hospitals or health care facilities (Pacemakers, Hearing Aids and
Other Medical Devices) may be using equipment that is sensitive to
external RF energy.
• Turn off your radio when on board an aircraft. Any use of a radio must be
in accordance with applicable regulations per airline crew instructions.
Note:
- Pacemakers
Defibrillators or other Implanted Medical Devices Persons with pacemakers,
Implantable Cardioverter-Defibrillators (ICDs) or other active implantable
medical devices (AIMD) should:
• ALWAYS keep the radio more than 15cm from their pacemaker when the
radio is turned on.
• Consult with their physicians regarding the potential risk of interference
from radio frequency transmitters, such as portable radios (poorly
shielded medical devices may be more susceptible to interference).
• Turn the radio OFF immediately if they have any reason to suspect that
interference is taking place.
• Do not carry the radio in a chest pocket or near the implantation site,
and carry or use the radio on the opposite side of their body from the
implantable device to minimize the potential for interference.
- Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the
event of such interference, you may want to consult your hearing aid
manufacturer to discuss alternatives.
- Other Medical Devices
If you use any other personal medical device, consult the manufacturer of
your device to determine if it is adequately shielded from RF energy. Your
physician may be able to assist you in obtaining this information.
Protect your hearing:
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
• Turn down the volume before adding headset or earpiece.
• Limit the amount of time you use headsets or earpieces at high volume.
• When using the radio without a headset or earpiece, do not place the
radio's speaker directly against your ear.
Note:
Exposure to loud noises from any source for extended periods of time
may temporarily or permanently affect your hearing. The louder the radio's
volume, the less time is required before your hearing could be affected.
Hearing damage from loud noise is sometimes undetectable at first and
can have a cumulative effect.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged antenna. If a damaged
antenna comes into contact with the skin when the radio is in use, a minor
burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or chains touch
exposed terminals of the batteries, may complete an electrical circuit
(short circuit the battery) and become hot to cause bodily injury such as
burns. Exercise care in handling any battery, particularly when placing it
inside a pocket, purse or other container with metal objects.
Long transmission
• When the transceiver is used for long transmissions, the radiator and
chassis will become hot.

• Do not use charger outdoors or in moist environments, use only in dry
locations/conditions.
• Do not disassemble the charger, that may result in risk of electrical shock
or fire.
• Do not operate the charger if it has been broken or damaged in any way.
• Do not place a portable radio in the area over an air bag or in the air bag
deployment area. The radio may be propelled with great force and cause
serious injury to occupants of the vehicle when the air bag inflates.
- To reduce risk
• Pull by the plug rather than the cord when disconnecting the charger.
• Unplug the charger from the AC outlet before attempting any maintenance
or cleaning.
• Contact Retevis for assistance regarding repairs and service.
