IMPORTANT NOTICE, FCC LICENSE REQUIRED FOR GMRS OPERATION
The GXT300/325/310/400/450 Series operates on GMRS (General Mobile
Radio Service) frequencies which require an FCC (Federal Communications
Commission) license. You must be licensed prior to operating on channels 1 - 7
or 15 - 22, which comprise the GMRS channels of the GXT300/325/310/400/450
Series. Serious penalties could result for unlicensed use of GMRS channels, in
violation of FCC rules, as stipulated in the Communications Act's Sections 501
and 502 (amended).
You will be issued a call sign by the FCC which should be used for station
identification when operating the radio on GMRS channels. You should also
cooperate by engaging in permissible transmissions only, avoiding channel
interference with other GMRS users, and being prudent with the length of their
transmission time.
To obtain a license or ask questions about the license application, contact the
FCC at 1-888-CALL FCC or go to the FCC's website:
Exposure To Radio Frequency Energy
Your Midland radio is designed to comply with the following national and
international standards and guidelines regarding exposure of human being to
radio frequency electromagnetic energy:
- United States Federal Communications Commission, Code of Federal
Regulations: 47 CFR part 2 sub-part J
- American National Standards Institute (ANSI)/Institute of Electrical &
Electronic Engineers (IEEE) C95. 1-1992
- Institute of Electrical and Electronic Engineer (IEEE) C95. 1-1999 Edition
- National Council on Radiation Protection and Measurements (NCRP) of the
United States, Report 86, 1986
- International Commission on Non-lonizing Radiation Protection (ICNIRP)
1998
To control your exposure and ensure compliance with the general population
or uncontrolled environment exposure limits, transmit no more than 50% of the
time. The radio generates measurable RF energy exposure only when
transmitting.

CHARGINGTHE OPTIONAL BATTERY PACK
Your GXT300/325/310/400/450 Series is equipped for using an
optional rechargeable NiMH battery pack (not included) which can be
recharged using a desktop charger (not included). Initial charge time
is 24 hours with a charge time of 12 hours thereafter. For maximum
battery life, we recommend charging the battery pack when the low
battery icon comes on. Remove the radios from the charger when the
charge time expires.
To charge using a Desktop Charger:
1. Place the rechargeable battery packs in the radios.
2. Connect the AC adapter into an AC wall outlet.
3. Insert the AC adapter plug (or DC Cigarette Lighter adapter if
charging in vehicle) into the desktop charger jack.
4. Place the units into the desktop charger slot and note that the LED
indicator with RED color will light up, indicating charging function.
In order to ensure that the battery pack is fully charged, it is
recommended that the battery pack be charged for at least 12
hours.
1. Only use our NiMH battery pack.
2. Do not attempt to charge alkaline batteries or any batteries
or battery packs other than the one indicated in the manual.
This may cause leakage and damage to the radio.
3. For long term storage of the radio, turn the radio OFF and
remove the batteries from the radio.
!
LOW BATTERY LEVEL INDICATOR
Your GXT300/325/310/400/450 Series has a LOW BATTERY
ICON which will only appear on the LCD display if the battery voltage

cause low power conditions
l Be sure you are on a GMRS channel - FRS channels are
restricted by the FCC to low power
l Be sure to set your radio to use Hi power.
