SAFETY INFORMATION

Guidelines: 
User awareness instructions should accompany device 
when transferred to other users. 
Do not use this device if the operational requirements 
described herein are not met. 
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. Trans-
mitting 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). 
Transmit only when people outside the vehicle are at least 
the recommended minimum lateral distance away, as 
shown in Table 1, from a properly installed according to 
installation instructions, externally-mounted antenna. 
NOTE: Table 1 lists the recommended minimum lateral 
distance for bystanders in an uncontrolled environment 
from transmitting types of antennas (i.e., monopoles over a 
ground plane, or dipoles) at several different ranges of 
rated radio power for mobile radios installed in a vehicle.
MOBILE ANTENNAS 
Install antennas at the center of the roof or the center of 
the trunk deck taking into account the bystander exposure 
conditions of backseat passengers and the recommended 
minimum lateral distances in Table 1. These mobile 
antenna installation guidelines are limited to metal body 
motor vehicles or vehicles with appropriate ground 
planes. The antenna installation should additionally be in 
accordance with:
a.) The requirements of the antenna manufacturer/
supplier. 
b.) Instructions in the Radio Installation Manual, 
including minimum antenna cable lengths. 
c.) The installation manual should provide specific 
information of how to install the antennas to facil-
itate recommended operating distances to all 
potentially exposed persons. 
Use only EFJohnson approved supplied antenna or 
EFJohnson approved replacement antenna. Unauthorized 
antennas, modifications, or attachments could damage 
the radio and may violate FCC regulations.   Antennas 
tested with EFJohnson radios are listed in Table 2.
APPROVED ACCESSORIES 
This radio has been tested and meets the FCC RF expo-
sure guidelines when used with the EFJohnson accesso-
ries supplied or designated for this product. Use of other 
accessories may not ensure compliance with the FCC’s 
RF exposure guidelines, and may violate FCC regula-
tions. 
For a list of EFJohnson approved accessories, refer to the 
radio service manual or contact the EFJohnson Company
