OPEN AND CLOSED MODES You can set your scanner to change the way it receives signals. These settings, called open mode and closed mode, affect how the scanner receives signals from communications systems that use some type of closed squelch (such as Motorola and EDACS systems). Ô You can set each of the scanner's channel storage banks to open or closed mode. In open mode, the scanner scans signals transmitted in all systems. The scanner stops on any ID code and only uses the ID list to look up ID text tags. In closed mode, the scanner stops only on signals that have an ID code which is found in the ID list for the bank. Also, the scanner scans signals transmitted only under the following conditions: • When the signals are in the FM mode. • When the signals are in the MOT, or ED mode and the signal's ID code matches the programmed ID code. You can also select the user or talk groups you want the scanner to receive in closed mode. When you set a channel storage bank to open mode, + appears under the bank's number while scanning. When you set a channel storage bank to closed mode, - appears under the channel Ô NOTE Ô • In open mode, you hear all active talk groups except those you specifically exclude, making it easy to hear everything going on. In closed mode, you hear only those talk groups you specify. This makes it easy to listen only to talk groups you are interested in and exclude others. • When you select a channel manually, any transmission opens squelch, regardless of the current mode. • When no ID code is programmed into the scanner, it receives the signal in MOT or ED mode. In open mode, the scanner stops on any transmission. If the ID is stored, the text tag appears on the display. Otherwise, the talk group ID appears on the display. In closed mode, the scanner only stops on a transmission if the ID is stored. Understanding Your Scanner's Modes 25
