Operating Modes and Features
GRMS/FRS Operation:
-Press and hold the Power On/Off button for 2 seconds to turn on power.
-Press the MODE button so the Channel number flashes.
-Select the desired channel with the Up (10) and Down (11) Buttons. When receiving a call, the RX icon appears to indicate an incoming call.
-Press and hold the PTT button (3) to transmit, then speak into the microphone clearly and slowly.
-Release PTT Button (3) to receive.
-Communication can only be accomplished when the channel of at least two parties are the same.
Channel Selection
In order to communicate with other GMRS/FRS units, both the transmit- ting and receiving party must be on the same frequency.
The GMRS672 has 22 channels (frequencies) indicated by the large digits on the LCD display panel. Channels 1 through 7 are the shared GMRS/FRS channels. Channels
To change the channel:
-From GMRS/FRS standby mode, press the MODE button (9) once; the channel number flashes.
-Press the Up Button (10) briefly to move to the next higher main chan- nel number.
-Press the Down Button (11) briefly to move to the next lower main channel number.

VOX Selection Mode
This option enables you to have
To set the radio for VOX operation:
-From GMRS/FRS standby mode, press and hold the MODE button for 2 seconds, or until the VOX icon appears on the display.
-To terminate VOX operation, press and hold the MODE button for at least 2 seconds; the VOX indication will disappear.
Channel Scan Operation
This feature allows you to monitor all channels automatically for valid signals. While scanning, you can transmit and receive. When a signal is received, the scan is interrupted and will return to scan mode approxi- mately 5 seconds after reception is terminated.
NOTE: While the scan function is active, the MODE/VOX button will be inoperative. The scan mode will reduce the overall battery life since the battery save function is overridden.
To enable the channel scan mode:
-From GMRS/FRS standby mode, momentarily press the Power (S) Button; (SCAN) will appear on the LCD display.
-The radio will display each channel
-If the unit doesn’t find any signals and you want to transmit, press the PTT button to return to home channel operation. The transceiver will automatically resume scanning approximately 5 seconds after the communication is completed.
-If there is no activity and you want to leave the scan mode, press the S button momentarily and the unit will return to normal operation;
the SCAN icon will disappear from the LCD display.

Button Beep (Key Tone)
This feature allows the transceiver to sound a confirmation tone whenever the following keys are pressed: Power On/Off/SCAN Button, Up/Down But- tons and MODE Button. This feature is always on.
Roger Beep Tone
The Roger Beep is a tone which is automatically transmitted whenever the PTT button is released and the tone is enabled. This tone alerts the re- ceiving party that the transmission has been terminated intentionally
To enable and disable the Roger Beep tone:
-From GMRS/FRS standby mode, press the MODE Button 2 times
until the flashing Roger Beep icon ( 
) appears with on or oF.
-Press the Up or Down Button to select the tone on or off as desired.
-When enabled, the tone icon ( 
) appears steady on the display.
-Press the PTT button momentarily to confirm selection.

on the LCD panel, recharge or install fresh batteries.
NOTES FOR GOOD COMMUNICATION
1 . The 22 channels of the GMRS672 are shared on a ‘take turns’ basis. This means other groups may be talking on any of the chan- nels. A common code of ethics/courtesy is to switch to another vacant channel and not to attempt to talk over someone who is already using the channel you first selected.
2.The GMRS672 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 units closer than 5 feet apart.
3.For best transmission results, always keep your mouth about
4.To increase battery life, use the SCAN feature sparingly. This feature will reduce operating time considerably.

Warning
•Do not operate the transceiver unless you are licensed to do so.
•Remove the batteries from the transceiver if it is not expected to be used for long periods. This will eliminate the possibility of chemicals leaking from the batteries and corroding the transceiver.
•Avoid exposing the transceiver to water or extremes of temperature.
•Do not use this device in or near a mining facility, which uses remotely triggered explosives or in areas labeled “Blasting Area”. Premature or accidental detonation may result.
•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.
•Do not use this device or change its batteries in potentially explosive atmospheres as sparks in such areas could result in an explosion.
•Turn your transceiver off wherever posted notices restrict the use of radios or cellular telephones. Facilities such as hospitals may use equip- ment that is sensitive to RF energy.
•Turn your transceiver off on board aircraft when requested to do so.
•Do not place your radio in front of a vehicle’s
