Scanning Operation - Vertex Standard VX-4000 Operating Manual

Scanning Modes
There are eight scanning modes, described in the list below. Each channel can be
independently enabled or disabled for scanning; only channels selected for scanning
within the enabled group are scanned. Also, as mentioned before, each group can
have up to two priority channels which are scanned more often than the non-priority
channels.
The SCAN modes and their corresponding displays are as follows:
Display Scanning Function
DSC
Dealer Scan (only within the current group)
USC
User Scan: only user-selected channels (only within the current group)
GDS
Group Dealer Scan: scan all Dealer-selected channels in all groups
GUS
Group User Scan: scan all User-selected channels in all groups
PDS
Priority Dealer Scan: DSC plus priority channel(s)
PUS
Priority User Scan: USC plus user priority channel(s)
DDW
Dealer Dual Watch: Monitor one channel and priority channel(s)
UDW
User Dual Watch: Monitor User-selected channel and priority channel(s)

Scanning Operation

With the microphone in its hanger, press the assigned Programmable Function
Button of the "SCAN" momentarily to activate scanning. Typically, "DSC" will
initially appear on the display, indicating Dealer Channel Scan as the scanning mode.
If you wish to change to one of the modes described in the list above, press the
assigned Programmable Function Button of the "SEL" button repeatedly until
that mode appears on the display.
If you pick up the microphone while no signal is being received, operation will shift
to a particular channel. Which channel that will be depends on which of the follow-
ing options the dealer has programmed for off-hook channel selection:
Scan Start Channel
Lifting the microphone causes operation to revert to the group and channel last se-
lected before scanning started or resumed.
Priority Revert
Lifting the microphone activates the Priority 1 channel in the current group. If no
channel is assigned level 1 priority, operation will be on the Priority 2 channel. If no
priority channels have been assigned, operation reverts to the Scan Start Channel.
Last Busy
Lifting the microphone causes operation to revert to the group and channel where
activity was last detected. If no activity was detected since turning on the radio,
operation reverts to the Scan Start Channel.
