involve the safety of life or property. ! You must take reasonable precautions to prevent harmful interference to other services operating on the same frequency. ! You must not transmit connection with commercial broadcasting.
Safety Information Your radio contains a low power transmitter. When the PTT button is pushed it sends out radio frequency (RF) signals. In August 1996, the FCC adopted RF exposure guidelines with safety levels for hand-held wireless devices. Cautions: • To maintain compliance with the FCC’s RF exposure guidelines, hold the entire radio, including the antenna, at least 2 inches (5 cm) from your face, with the antenna pointed up and away from your face.

8’th press – Call 6) Emergency ( EMG ) Call Button : This radio has a quick access button( EMG ) to the Emergency and Assistance Channel. This channel is not monitored by local authorities. When using this channel, EMG appears on the display.
Small Segment Display: Displays CTCSS tone option in the channel from 00 to 38, and also displays the caller ID number(01–10) when caller ID function is active. Coded Tone Controlled Squelch System(CTC) Indicator: Icon appears when the CTCSS tone function is active. Dual Watch mode Indicator: Icon appears when dual watch mode is active. Voice Activated Transmission (VOX) Indicator: This function allows handsfree conversation. The Icon appears when the VOX mode is activated.
GMRS-7000 has 15 main channels and 38 sub-channels. ! 14 Frequency channels ! 38 CTCSS Code ( indicated by CTC icon on the LCD ) To select the channel ! Turn the radio on. ! Press MODE button once, [XX] digit will blink on the LCD. XX is a channel. ! Press up[″]or down[…] button to choose the channel. ! Press the PTT button or MODE button to confirm. To set the tone codes(CTCSS) ! Press MODE button once more, [XX oF, 01 up to 38] will appear and CTC icon and tone code digit will blink on the LCD.
To set the dual watch(DW) channel ! Press the up[″]or down[…] button to choose the channel. “ oF” means no DW mode. “ 01 up to 15” means the channel is dual-watched. ! Press the PTT button or MODE button to confirm. 5) Power Selection Mode This feature permits selection of the transmitting power level to high or low. Using low power, the unit will have a lower transmit range but battery life will Be increased.
To set your favorite call ringer signal. ! Press the MODE button until the [C 01 or up to 03] appears on the LCD. ! Press the up[″]or down[…] button to select the call melody type. ! Press the PTT button to confirm. ! To activate the call, click the “ PTT” button twice quickly. 9) Out-of-range Alarm Icon blinks as the receiving signal is getting weaker.
