mode, the scanner then goes to the transmission and displays the talk group ID on the bottom line of the dis- play. In the closed mode, the scanner only goes to trans- missions with IDs that match talk group IDs you have stored in the bank's talk group ID list which are not locked out.

Because EDACS scanning requires clear reception of the control channel at all times, EDACS systems tend to have a smaller usable area. An external antenna can greatly improve EDACS scanning in a fringe area. If you are having trouble scanning an EDACS system, try man- ually selecting the data channel. If you are getting good reception, the scanner will indicate talk group á0(Vòñ. Try changing your location or using an outdoor antenna to improve reception.

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).

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. In closed mode, 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, ö appears under the bank's number while scanning. When you set a channel storage bank to closed mode, V ap- pears under the channel storage bank's number while scanning. +,!* or á(+/! appears while the scanner is
