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:

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:

- 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 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

level is low. At this point, the battery needs to be charged for at least

12hrs.

POWER ON/OFF AND VOLUME

Rotate the POWER/VOLUME knob clockwise to turn the radio on and

increase the volume level. Rotate the control counter-clockwise to

reduce the volume level and to turn the radio off. During Power On,

the radio will beep 3 times with different tones, the LCD will display a

“self-test” message for 1 second and the LCD display will indicate the

last channel selected.

TRANSMITTING AND RECEIVING A CALL

To communicate, all radios in your group must be set to the same

channel and Privacy Code.

2. Press and hold the PTT button and speak in a normal voice

into the microphone. The TX icon will appear continuously

on the LCD Display while transmitting.

Your GXT Series radios are designed to give you maximum range

under optimum conditions.

Optimum Conditions are:

lOver water

lOpen rural areas without obstructions

lFlat areas where you can see the other person

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.
