IMPORTANT NOTICE, FCC LICENSE REQUIRED FOR GMRS OPERATION

The GXT444 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 GXT444. 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:

www.fcc.gov/services/personal/generalmobile/licensing.html

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:

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.

CHARGING THE OPTIONAL BATTERY PACK

Your GXT444 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 GXT444 has a LOW BATTERY ICON which will only

To ensure you get maximum range:

lBe sure to use fresh or fully charged batteries - low batteries will

cause low power conditions

lBe sure you are on a GMRS channel - FRS channels are

restricted by the FCC to low power

lBe sure to set your radio to use Hi power.
