Locking Out Talk Group Ids; Trunking Delay; Priority Talk Group Id Scanning - Radio Shack Pro 94 Manual

8/17/2015
Trunkscanning allows you to scan just the talk group IDs programmed in the talk group ID lists. The scanner will scan IDs in all the
selected trunking banks. You cannot just trunk some banks and trunkscan others.
Note: When you trunkscan IDs with the Status Bit Ignore function set to off, you may miss transmissions with special status bits.
See Setting the Status Bit Ignore Function.
While trunking any bank, press SCAN to begin scanning the lists you have stored. SCAN will appear in the display and SCAN Id
will move across the display.
Note: If you don't have any talk group IDs stored, the scanner will beep twice, Error will briefly appear in the display, then
­­ ­­­ will stay in the display. Because there are no IDs programmed, the scanner will not receive any IDs. Press
SRC(LIMIT) to return to trunking.
Note: If one or more of the IDs you stored are incorrect, Error flashes twice and the scanner beeps several times, then the
scan list numbers appear at the top of the display. To correct this, delete at least one of the incorrect IDs. See
Programming Talk Group IDs.
To turn scan lists on or off, while trunkscanning the bank, use the number keys to turn the scan list's number on or off. Only the IDs in
lists that are turned on will be scanned.
Note: One of the five scan lists will always be active. You cannot turn off all of them.
Press SRC(LIMIT) to return to trunking (all IDs).
Locking Out Talk Group IDs
Many municipal and commercial services use trunking systems to transmit signals from such devices as water meter transmitters,
door alarms, and traffic signals. Some signals are encrypted, as well, and most are not voice signals. Since all these are assigned
IDs just like other users, you may want to lock out reception of these ID signals. You can lock out up to 100 IDs at one time.
With the EDACS partial ID feature, you can program agencies and fleets (in AFS format) as 1 ID and lock them out.
To lock out an ID, while trunking a bank, press S/S(L­OUT) when the ID appears in the display. The ID is locked out, and the
scanner resumes trunking.
Note: If you lock out an ID while trunking, it is also locked out of the scan list(s).
To unlock a single ID, while trunking the bank that has the ID:
1. Press and hold S/S(L­OUT) until you hear two short beeps.
2. Press or
3. Press S/S(L­OUT). The ID is unlocked, and the next locked ID appears. If you have unlocked all the IDs, the scan list
will appear.
4. Press SCAN to return to trunkscanning or SRC(LIMIT) to return to trunking.
To unlock all IDs in a bank, while trunking the bank:
1. Press and hold S/S(L­OUT) until you hear two short beeps. If there are no IDs locked out, you will just hear 3 short
beeps.
2. Press SVC(E) to unlock all the IDs at once in the bank. When you unlock all the IDs, the scan list appears.
3. Press SCAN to return to trunkscanning or SRC(LIMIT) to return to trunking.
Trunking Delay
Sometimes a user might pause before replying to a transmission. You can set the scanner to hold on an ID for 5 seconds to wait for
a reply. That way, the scanner continues to monitor the ID for 5 seconds after the transmission stops before resuming scanning.
To turn trunking delay on or off for all IDs, press DELAY while trunking. DLY will appear or disappear in the display.
Note: If you consistently miss responses even with scan delay turned on when trunking a Motorola Type I system, try
changing the fleet map being used. See Programming a Motorola Type IIi or Type I System.
Monitoring a Single Talk Group ID
To monitor a single ID in a bank, while trunking, press HOLD(A/B) while any ID is displayed. HOLD appears in the display and the
scanner stays on the selected ID. To listen to (and hold) a different ID, use the number keys to enter an ID and press HOLD to
advance to the new ID.
To stop monitoring the ID, Press SCAN to return to trunkscanning or SRC(LIMIT) to return to trunking.
Monitoring Talk All Group IDs
You can use your scanner's display to monitor the talk group IDs of a trunked system for activity. While you cannot hear
conversations in this mode, it is an excellent way to determine which talk group IDs are the most active.
To monitor IDs, press and hold .(MON/CLR) until SEARCH and the channel number flash. All activate group IDs appear in quick
succession. When you monitor IDs, any IDs you have locked out also appear.
To stop monitoring IDs, press SRC(LIMIT) again.
Priority Talk Group ID Scanning
You can set 1 ID in each talk group ID list (1­5) as priority so during trunkscanning the scanner checks that ID more frequently than
the others in the list. The ID set in List 1 has the highest priority of all.
To set an ID, while trunkscanning the ID lists, press PROG. A number showing the current ID list (1­5) appears at the top of the

to select the ID you want to unlock.
