EDACS systems often provide users with an 'Emergency' mode on their radios. Users in trouble can alert the dispatcher and other units and get priority access to the radio system. When a user activates Emergency mode, EMERGENCY will flash the display during the entire transmission. At the beginning of each transmission it will sound a distinctive emergency alert tone three times. To turn Emergency Alert ON/OFF, enter into the Menu mode. Select 2:SCAN OPTION / 2:TRUNK - select Bank number - 9:EMERGENCY ALT / 1:ON or 2:OFF by rotating the VFO and pressing E.

Patch Tracking

The BC250D can follow EDACS patched talkgroups.

EDACS systems sometimes bring several talkgroups together in a 'Patch'. A patch might be used by a police agency at night to provide a single channel with a single dispatcher for a wide area. A patch is created when a single, temporary talkgroup substitutes for the original talkgroups. While the patch is running, which may be for hours or days, the original talkgroups cease to be used. If you were monitoring one of these talkgroups, you might think there was no traffic, but in fact the talkgroup was operating at the different temporary number.

If a talkgroup in your Scan List is patched, your scanner will continue to receive it under its new identity until the patch has ended. When a patch is being received, the radio will display PATCH ID, and will show the temporary common talkgroup plus all the included talkgroups in a cycling display.

The BC250D is limited to following two patches.

The temporary talkgroups used for patches are usually found in AFS code 15-xxx, and sometimes 00-xxx.

EDACS SCAT

With the EDACS SCAT feature turned “ON”, the data stream transmissions will be eliminated allowing you to clearly monitor the voice communications on EDACS SCAT systems.

To monitor EDACS SCAT systems you only need to turn this feature 8:EDCS SCT. ON with designated frequency. You do not need to enter group ID’s.

Note: As EDACS SCAT is different from the other tracking feature, and it is not a feature which the scanner tracks any ID, you do not need to program Talk Group ID in the Menu mode.
