SAFETY TRAINING INFORMATION
WARNING.
Your Entel radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational 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. This radio is NOT intended for
use by the “General Population” in an uncontrolled environment.
Use only Entel approved accessories. Use of accessories other than those specified may result in RF exposure levels exceeding the FCC requirements for
wireless RF exposure.
CAUTION.
To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:-
DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A
proper antenna is the antenna supplied with this radio by the manufacturer or antenna specifically authorized by the manufacturer for use with this radio.
DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more than 50% of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting when the “TX indicator” lights red. You can cause the radio to transmit by pressing the “PTT” switch.
ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when
transmitting and only use approved accessories to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your
transmission the best sound quality, hold the transceiver at least 5 cm (2 inches) from your mouth, and slightly off to one side. The information listed above
provides the user with the information needed to make him or her aware of RF exposure, and what to do to ensure that this radio operates within the FCC RF
exposure limits.
Electromagnetic Interference/Compatibility
During transmissions, your Entel 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. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals,
aircraft, and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as a consequence of their employment. These persons should be made fully aware of
the potential for exposure so they can exercise control over their exposure.
Changes or modifications to this device, not expressly Approved by Entel UK could invalidate your authority to operate this device under FCC regulations.
