This device contains licence-exempt transmitter(s)/receiver(s) that comply with
Innovation, Science and Economic Development Canada’s licence-exempt
RSS(s). Operation is subject to the following two conditions:
(1) This device may not cause interference.
(2) This device must accept any interference, including interference that may
cause undesired operation of the device.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux
appareils radio exempts de licence. L’exploitation est autorisée aux deux
conditions suivantes :
(1) l’appareil ne doit pas produire de brouillage;
(2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi,
même si le brouillage est susceptible d’en compromettre le fonctionnement.
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 lou-
der 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.

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 Govern-
ment 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
Before using this radio, read this guide which contains
important operating instructions for safe usage and RF
