User's Manual
To avoid injury, read all operating instructions and the following safety informa-
tion before using the Wireless Speaker Microphone. 
Exposure to Radio Frequency Energy:
The unit transmits and receives radio frequency (RF) energy through its an-
tennas. The antennas are located at the top edge of the unit. The Wireless 
Speaker Microphone is designed and manufactured to comply with the limits 
for exposure to RF energy set by international regulatory agencies, including 
the FCC of the United States, IC of Canada, MIC of Japan, and the Counsel of 
the European Union, among others. The unit has been tested and meets the 
FCC, IC, and European Union RF exposure guidelines for 802.15 operation. To 
ensure exposure levels remain at or below the maximum safe levels, when car-
rying the unit ONLY use the Wireless Speaker Microphone with the manufac-
turer’s supplied clothing clip or a non-metalic holder that ensures the antenna 
remains greater than 10mm (2/5 inch) from your body at all times. An external 
antenna is connected to the output connector on the mobile charger or to 
the output connector on the XBDA bidirectional amplier. Always  keep your 
body at least 20cm (8”) from the antenna whip. The XBDA is only approved 
for use with this mobile charger unit in accordance with FCC regulations� refer 
FCC ID: I7OBT-24D�
Potentially Explosive Atmospheres:
Turn off the unit when in any area with a potentially explosive atmosphere. 
Do not charge, and obey all signs and instructions. Sparks in such areas could 
cause an explosion or re, resulting in serious injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, 
marked clearly. Potential areas may include: fueling areas (such as gas sta-
tions); below deck on boats; fuel or chemical transfer or storage facilities; 
vehicles  using  liqueed  petroleum  gas  (such  as  propane  or  butane);  areas 
where the air contains chemicals or particles (such as grain, dust, or metal 
powders); and any other area where you would normally be advised to turn 
off your vehicle engine.
Radio Frequency Interference:
Radio frequency emissions from electronic equipment can negatively affect 
the operation of other electronic equipment, causing them to malfunction. 
Although the Wireless Speaker Microphone is designed, tested, and manufac-
tured to comply with regulations governing radio frequency emission in coun-
tries such as the United States, Canada, the European Union, and Japan, the 
wireless transmitters and electrical circuits in the unit may cause interference in 
other electronic equipment. Therefore, please take the following precautions:
