GME TX670 is a 2-watt handheld UHF CB radio that offers a wide range of features for clear and convenient communication. With its programmable scan function, you can scan up to 80 UHF CB channels to find active conversations or monitor specific channels. The built-in CTCSS (Continuous Tone Coded Squelch) system allows you to reduce background noise and improve reception quality by filtering out unwanted signals. The TX670 also features adjustable RF power, allowing you to conserve battery life by using the 1-watt low power setting for short-range communication.

theuserthatthebatteriesarealmostdischarged.
Battery Usage
Thetimetakentodischargethebatterieswilldependonhow

theamountofpowerdrawnfromthebatteries.
Standby Mode
TheTX670willautomaticallyenterthe‘Standby’modewhen
itisinactive(i.e.nottransmittingorreceivingsignals).Whilein
Standbymodeitwillstillcheckforincomingsignalsbutitwill
drawconsiderablylesspowerfromthebatteries.Assoonasa

thebatterylifebymanyhours.
Using CTCSS
Ifyouareexpectingtoreceivesignalsonabusychannel,you
canprogramthatchannelforCTCSSoperationandgettheother

GME TX670 is a 2-watt handheld UHF CB radio that offers a wide range of features for clear and convenient communication. With its programmable scan function, you can scan up to 80 UHF CB channels to find active conversations or monitor specific channels. The built-in CTCSS (Continuous Tone Coded Squelch) system allows you to reduce background noise and improve reception quality by filtering out unwanted signals. The TX670 also features adjustable RF power, allowing you to conserve battery life by using the 1-watt low power setting for short-range communication.
