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. When you are talking the other parties can not use the channel!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). We do recommend, when possible, to use the Low power setting. 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. This allows you to scan all the channels you have designated in your scan list (see Creating Scan List). The next is scan with a Priority channel (channel 1). This scan allows you to monitor channel 1 more often than the other channels while scanning (for this scan to work properly you must have at least 6 channels in the scan list). This allows you to scan the priority channel and a channel of your choice. You must have more than one channel programmed in the scan list in order for your 75-440 to scan them. The advanced scan function of the radio allows optionally looking for carrier or carrier with "CTCSS" or "DCS. " Activating, Deactivating Normal Scan 1) Press the "CALL" button + key.
