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
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.
