C95.1-1999 Edition 

To control your exposure and ensure compliance 

with the occupational/controlled environment exposure 
limits, always adhere to the following procedures.

Guidelines:

•

Do not remove the RF Exposure Label from the 
device. 

•

User awareness instructions should accompany the 
device when it is 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, release the PTT button. 
Transmitting 50% of the time, or less, is important 
because this radio generates measurable RF energy 
exposure only when transmitting (in terms of 
measuring for standards compliance).

•

Hold the radio in a vertical position in front of face 
with the microphone (and the other parts of the radio, 
including the antenna) at least one inch (2.5 cm) away 
from the nose. Keeping the radio at the proper distance 
is important because RF exposures decrease with 
distance from the antenna. The antenna should be kept 
away from eyes. 

•

When worn on the body, always place the radio in an 
EFJohnson approved clip, holder, holster, case, or 
body harness for this product. Using approved body-
worn accessories is important because the use of 
EFJohnson or other manufacturer’s non-approved 
accessories may result in exposure levels which 
exceed the FCC’s occupational/controlled environ-
ment RF exposure limits. 

•

Use only EFJohnson approved supplied or replace-
ment antennas, batteries, and accessories. Use of non-
EFJohnson approved antennas, batteries, and accesso-
ries may exceed the FCC RF exposure guidelines. 

•

service manual or marketing accessory lists or contact

This device complies with Part 15 of the FCC rules. 

Operation is subject to the condition that this device does 
not cause harmful interference. In addition, changes or 
modification to this equipment not expressly approved 
by the E.F. Johnson Company could void the user’s 
authority to operate this equipment (FCC Rules, 47CFR 
Part 15.19). 

DO NOT operate it in areas that are sensitive to RF 

energy such as aircraft, hospitals, blasting sites, and fuel 
storage sites. Areas with potentially flammable atmo-
spheres are usually, but not always, clearly posted. These 
may include gas stations, fuel and chemical storage and 
transfer stations, below deck on boats, and areas where 
the air contains flammable chemicals or particles such as 
grain dust or metal powders. 

Dispose of the nickel metal-hydride (NiMH) battery 

used by this radio in accordance with local regulations. 
DO NOT dispose of it in fire because it can explode. 
Also, do not short the terminals because it may become 
very hot.
