USING THE WEATHER RADIO
Your GMR648-2CK radio can receive weather broadcasts from the NOAA National Weather Service. When in the Weather Radio Alert mode, the system functions as it does in GMRS mode but also monitors the selected weather channel for alerts when not communicating.
While using the Weather Radio, you are not able to receive GMRS communications.
1)To turn ON the Weather Radio Broadcast mode,
press the wx/alert key. The 
icon appears on the display.
2)Press the ch/scan key, and press the ▲ or ▼ key to increase or decrease the number to the desired Weather Channel.
3)To exit the Weather Radio Broadcast mode,
press the wx/alert key. The 
icon disappears from the display.
•To change the channel continuously, press and hold the ▲ or ▼ key for more than 1 second.
•When in the Weather Radio Broadcast mode, you can only set the Key Lock from the Menu mode.
Choosing an Emergency/Weather Channel
There are 7 NOAA channel frequencies available and these frequencies are common between the US and Canada. You will need to know what frequency is being transmitted in your location.
1)Press and hold the wx/alert key. The 
icon appears on the display.
2)When the unit receives a warning signal, it beeps
for 5 seconds. The 
icon, the 
icon and channel indicator blinks.
3)To turn OFF Weather Alert, press and hold the
wx/alert key. The 
icon disappears from the display.
•When Weather Alert is activated, the highest priority is given to this function. It checks the weather alert signals every 7 seconds and switches to the warning receive mode automatically.
•Weather Alert is activated even if key beep is turned off.

REGULATORY INFORMATION
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1)This device may not cause harmful interference.
(2)This device must accept any interference received, including interference that may cause undesired operation.
Important: Changes or modifications to this unit not expressly approved by Uniden could void your authority to operate this unit. Your radio is set up to transmit a regulated signal on an assigned frequency. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. Any adjustments to your radio must be made by qualified technicians.
To be safe and sure:
• Never open your radio’s case.
• Never change or replace anything in your radio except the batteries.
Your radio might cause TV or radio interference even when it is operating properly. To determine whether your radio is causing the interference, turn it off. If the interference goes away, your radio is causing it. Try to eliminate the interference by moving your radio away from the receiver. If you cannot eliminate the interference, the FCC requires that you stop using the radio.
Hazardous Environments: Do not operate the radio in hazardous environments. Explosion or fire may result. Do not operate the radio near unshielded electrical blasting caps.
Under certain conditions, radios can interfere with blasting operations and may cause an explosion. Turn your radio OFF to prevent accidental transmission when in a blasting area or in areas posted: "Turn off two-way radio." Construction crews often use remote control RF devices to set off explosives.
Care and Safety: To clean the radio, use a soft cloth dampened with water. Do not use cleaners or solvents because they can harm the body of the unit and leak inside, causing permanent damage. Use a dry, lint-free cloth to clean the battery contacts. Do not submerge the unit in water. If the unit gets wet, turn it off and remove the batteries immediately.
Dry the battery compartment with a soft cloth to minimize potential water damage. Leave the battery compartment cover off overnight to ensure complete drying. Do not use the radio until the unit is completely dry.
RF EXPOSURE INFORMATION
WARNING! Read this information before using the radio. In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC
96-326 adopted an updated safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters.
Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of the radio complies with the FCC guidelines and these international standards.
Never allow children to operate the radio without adult supervision and the knowledge of the following guidelines.
WARNING! It is up to the user to properly operate this radio transmitter to insure safe operation. Please adhere to the following:
Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the radio, or result in violation of FCC regulations. Do not use the radio with a damaged antenna.
If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for a replacement antenna.
Body-worn Operation
This device was tested for typical body-worn operations using the supplied belt-clip.
To maintain compliance with FCC RF exposure requirements, Body-worn operations are restricted to the supplied belt-clip.
For hand-held operation, the radio should be held
1 inch from the user's face. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and should be avoided.
For more information about RF exposure, please visit the FCC web site at www.fcc.gov.
