21About Your Scanner
FM Mode
The FM mode sets the scanner to receive transmissions
using frequency modulation (FM), used for most public
safety transmissions, as well as broadcast, business,
and amateur radio transmissions. When the scanner re-
ceives a transmission on a channel set to the FM mode,
it always stops on the transmission.
Motorola Mode
You can set your scanner so it decodes the talk group
IDs used with Motorola trunking systems. This setting is
called the Motorola mode.
Motorola systems are...

About Your Scanner
Type I systems are usually organized with different user
groups assigned to different fleets. For example, a valid
fleet-subfleet ID identifying all detectives within a police
department might be 
òòòVñð
òòòVñðòòòVñð òòòVñð, where 000 identifies all po-
lice users and 12 identifies the Detective division.
To properly map the raw Type I data to the correct fleet-
subfleet format, you must program the correct fleet map
into the scanner. Fleet map information is widely avail-
able on...

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 banks 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...
