[. . . ] In this case you will receive only messages coming from parties sending a proper TX signaling. During "CTCSS/DCS" operation, the radio may be set-up so that the appropriate CTCSS/DCS decoder enables the speaker. CTCSS/DCS If more than one station is transmitting at the same time, this will cause interference!Wait until the channel is clear before transmitting. · Monitor Button The Monitor button can enable or disable "GROUP MODE (CTCSS/DCS)" if programmed for that channel. Press and release the"MON" button: "SAT" icon is displayed. Press the "MON" button: "SAT" icon is not displayed. NOTE: if "SAT" icon is never displayed, "CTCSS/DCS" tone is not programmed. 3) Press and Hold "MON" button for three seconds, internal squelch will be disabled and your speaker is un-muted. Press and release the "MON" button to restore the squelch to normal operating condition. Transmitting 1) Ensure that the channel is not busy otherwise you will create interference. 3) Start talking at a normal voice level at approximately 2. 5 inches from the microphone (keep the "PTT" button pressed). 4) When you have finished talking, release the "PTT" button. It will not increase the distance you can transmit, but rather will make you heard distorted. Do not release the "PTT" button before your message is over or start talking before pressing "PTT", otherwise your message will be "chopped". A GMRS handheld radio does not normally allow you to talk and receive simultaneously, for this reason make your messages short. Your radio is programmed with a timeout timer which will automatically turn off the transmitter if you talk longer than 90 seconds. In this case release the "PTT" and wait for few seconds, the radio TX features will be automatically restored. Adjusting Transmit Power Your 75-440 can transmit with two power levels according to the distance of your party's station(s). This will increase the battery life and will reduce the risk of interference with other stations not in your radio network that may be sharing the same channel with you. 1) To change the channel's Power Output level from high (2 Watts) to Low (0. 5 Watt), or vice versa, Press and Hold "FUNC" key for about 2 seconds. A small "LOW" will appear in the lower left corner of the display to indicate "Low Power". If the battery icon is "blinking" (Low Battery indication), the Unit will automatically switch to Low Power when transmitting in order to help prolong the Battery's operational life. In this case, two short beeps will be heard when you press the "PTT" key before the radio transmits. Page. 14 75-440 User manual Scanning channels Your 75-440 has three types of scanning available.
