Do not open your radio to make any internal adjustments. Your radio is set up to transmit a regulated signal on an assigned frequency. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. [. . . ] Press and hold the wx/ctcss button for 2 seconds. Press the up or down button repeatedly to select one of the CTCSS codes (0-38). After selecting the desired CTCSS code, press the wx/ctcss button again. You must press the wx/ctcss button within 10 seconds or the unit will time out. If not, the setting will not be made. 4. To turn off the CTCSS code, press the up or down button until the code is selected. If the code is selected on your radio, you can receive any signal on that channel regardless of the CTCSS code settings of the people in your party. 8 Scan Mode Your radio also allows you to scan for activity from other transmitting radios regardless of the channel and code setting. Make sure all of your CTCSS codes are set to "0" prior to scanning. Otherwise, during a scan cycle, your radio will only check for that specific channel and code combination. Press the scan/vibrate button to begin scanning channels. The LCD will indicate that you are in scan mode. If a signal is present, the radio will stop on the active channel. It will remain on the channel until the transmission ends. After 2 seconds, it will resume scanning. To resume scanning prior to the transmission end, press scan/vibrate again. Press the scan/vibrate, wx/ctcss, call/vox, PTT, up, or down button to exit the scan mode, stopping at the current channel. If you press scan/vibrate to exit the scan mode, the radio must be actively scanning. 9 Monitor Mode The Monitor Mode is used to check activity on a specific channel. It will allow you to receive signals that are considered too weak. Press and hold the MON button until you hear a series of beeps. You will hear background noise if the channel is clear. Don't transmit if you hear conversation. To turn Monitor Mode off, press the MON button again. Talking on Your Radio To talk to others using the radio; 1. Determine your communicating channel and/or code setting with the other members of your party (refer to "Choosing a Channel and CTCSS" on page 7).
