These LED’s are used for backlighting as well. 9)External speaker/mic jacks : Connect an optional speaker/mic or headset, if desired.
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. Scan Indicator: This function allows users to scan a channel to search for a valid signal. 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.
Volume setting : Press up[″]or down[…] button to adjust a level that is comfortable for you while monitor is active. 2) Setting the Channel and Tone Code(CTCSS) GMRS-1200 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.
the LCD. * DW icon will appear 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 that is dual-watched. * Press the PTT button or MODE button to confirm. 5) Roger tone This feature will give the tone signal to other parties when transmitting finished (when PTT button is released.) To activate or disable the Roger tone * Press the Mode button until [rb on or oF] and the roger icon blink on the LCD.
selected, the radio that is receiving the signal displays the Caller ID number of the transmitting radio. 9) Weather alert setting To set the Weather alert receiving mode * Press the MODE button until the [AL on or oF] blinks * Press the up[″]button or down […]button to set the alert function. * While the alert is ON, weather icon will blink both in FRS and weather mode. * Weather icon will stop the blinking on the LCD when the alert is OFF.
13) Channel Scanning This feature allows you to monitor all activated channels while scanning. To activate the Scan * Press the SCAN button * Radio will begin scanning. * When in scan mode, the display will show each scanning channel. * After an activated channel is scanned and received signal and then if there is no more signal, the scan will resume automatically ** Once a channel has been scanned, pushing the monitor button makes the radio resume the scanning with the scanned channel skipped.
* Low battery – one segments is displayed * Low battery Warning – one segments will blinking. 4.
