Notes for Better Communication
1. Your MK1995 GMRS radio has been designed to maximize
performance and improve transmission range in the field. To
avoid interference, it is recommended that you do not use the
unit closer than 5 feet from another unit.
2. For better transmission results, keep your mouth about 2-3
inches from the microphone and speak slowly in a normal
voice.
3. Reverse polarity( + / - ) may cause serious damage to the unit.
Make sure not to reverse the polarity( + / - ) of the batteries in the
battery compartment.
25
SpecialWarning
1. Do not operate the transceiver unless you are licensed to do so.
2. Avoid exposing the transceiver to water or extreme tempera-
tures.
3. Do not attempt to modify or in any way increase the output of
this transceiver. Its output is designed to meet the legal limits
set by the FCC.
4. Do not use this device or change its batteries in potentially
explosive atmospheres as sparks in such areas could result in
an explosion.
5. Turn your transceiver off wherever posted notices restrict the
use of radios or cellular phones. Facilities such as hospitals may
use equipment that is sensitive to RF energy.
