To select a CTCSS squelch code, press the menu button once or until “tc” is shown on the display. The small flashing numbers to the right represent the current squelch code setting. “OF” (off) indicates that the CTCSS system is off. Use the UP and DOWN buttons to select the desired squelch code number. To allow the transceiver to receive all messages on a particular channel select the “OF” (off) setting. After 5 seconds, the unit will return to the standby mode and the CTCSS squelch code will be effective on all
14 channels. The Display will indicate the current channel number with large digits on the left and the current CTCSS squelch code with the smaller digits to the right. Only the channel number will be displayed if the CTCSS system is off.
