Trouble shooting
Silent
• The AC adapter is not plugged in or loose
• The 4-core connecting cable is not plugged in or loose
• Volume is not adjusted
Adjust the volume button (“I-v” and “O-v”) on the host to loud“+”
Whistle
• Installation environment noise performance is poor, or too much other noise, you should make
the distance larger between the host and the outside speaker or adjust the volume (“I-v” and
“O-v”) down
• If the volume knob to the minimum, the speaker volume is still very big, please adjust the
microphone sensitivity knob (“I-v” or “O-v”) at the bottom of the host
Staccato
• The spokesman from the microphone too far away, it should be a little closer (less than the
20cm better)
• When one party to speak, the other to grab, then will be mutually exclusive
• Ambient noise is too strong, the corresponding speaker volume down, or require the speaker
close to the microphone a little

Warnings
This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide commu-
nications 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 req-
uires users to be fully aware of and able to control their exposure to meet occupational require-
ments. 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.

local government radio management departments equipment authorization for this radio could
violate the rules.
FCC Requirements:
• This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
• This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communicat-
ions. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
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.

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 requirements to be exceeded.
• During transmissions, your radio generates RF energy that can 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.
• The device complies with RF specifications when the device used at 5mm from your body.
Third-party belt-clips, holsters, and similar accessories used by this device should not contain
any metallic components. Body-worn accessories that do not meet these requirements may not
comply with RF exposure requirements and should be avoided.
• DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such
as hospitals, aircraft, and blasting sites.
Avoid Choking Hazard
Small Parts. Not for children under 3 years.
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
• Use careful with the earphone maybe possible excessive sound pressure
from earphones and headphones can cause hearing loss
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.
Safety Operation

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 Retekess for assistance regarding repairs and service.
