signal is present. EVX-531 can scan both digital and
analog frequency programmed channels simultane-
ously.
To activate scanning:
 Press (or press and hold) the assigned Program-
mable key to activate scanning: the LED indicator
will glow with a pre-dened color.
 The scanner will search the channels of each
channel, looking for active ones; it will pause
each time it nds a channel on which someone is
speaking.
 Press (or press and hold) the assigned Program-
mable key again to disable scanning. Operation
will revert to the programmed revert channel.
Note: Your dealer may have programmed your radio
to stay on one of the following channels if you press
the PTT switch during scanning pause:
 “Scan Pause” channel (“Talk Back”)
 “Last Busy” channel
 “Priority-2” channel
 “User Programmed” channel (“Select Channel”)
The channel which dened in the CH Selector
knob.
group scan
The Scanning feature is used to monitor multiple
channels programmed into the transceiver. While
scanning, the transceiver will check each channel of
the programmed group for the presence of the signal,
and will stop on a channel if a signal is present.
Press (or press and hold) the assigned programmable
key to activate the scanning on the selected groups.

dual Watch
The Dual Watch feature is similar to the SCAN fea-
ture, except that only two channels are monitored:
 The current operating channel; and
 The Priority-2 channel.
To activate Dual Watch:
 Press (or press and hold) the assigned Program-
mable key.
 The scanner will search the two channels; it will
pause each time it nds a channel on which some-
one is speaking.
To stop Dual Watch:
 Press (or press and hold) the assigned Program-
mable key.
 Operation will revert to the “Dual Watch Revert”
channel.
Fm scan (FolloW-mE scan)
The FM Scan feature checks a User-assigned Priority
Channel regularly as you scan other channels. Thus,
if only Channels 1, 3, and 5 (of the 8 available chan-
nels) are designated for “Scanning”, the user may
nonetheless assign Channel 2 as the “User-assigned”
Priority Channel via the FM Scan.
To activate FM Scan, rst select the channel you want
to designate as the “User-Assigned Priority Channel”
and press (or press and hold) the assigned program-
mable key. Then rotate the CH Selector knob to re-
call to the “Scanning Start” channel which has been
programmed by your dealer to activate the scanner.
When the scanner stops on an “Active” channel, the
User-assigned Priority Channel will automatically be
checked every few seconds; if activity is found on the
User-assigned Priority Channel, the radio will switch
between it and the Dealer-Assigned Priority Channel,
if any.

ta scan
Press (or press and hold) the assigned Programmable
key to toggle the TA (Talk Around) scan feature “On”
and “Off”.
While TA scan is proceeding, the transceiver will
search both the transmit and receive frequencies.
When a signal is encountered on the receive frequen-
cy, the EVX-531 will pause until the signal disap-
pears. When a signal is encountered on the transmit
frequency, the transceiver will check for activity on
the receive frequency every few seconds (interval
programmed by your Vertex Standard dealer).
Note: The TA Scan feature does not activate on the
Simplex Channel.
scan sEt
Press (or press and hold) the assigned Programmable
key to add/delete the current channel to/from your
scanning list.
When the scanner is stopped, you may remove the
channel from the scan list temporarily by pressing (or
press and holding) this key.
talK around (ta)
Press (or press and hold) the assigned Programmable
key to activate the Talk Around feature when you are
operating on duplex channel systems (separate re-
ceive and transmit frequencies, utilizing a “repeater”
station). When the Talk Around feature is activated,
the LED indicator will glow with a pre-dened color.
The Talk Around feature allows you to bypass the
repeater station and talk directly to a station that is
nearby. This feature has no effect when you are oper-
ating on “simplex” channels, where the receive and
transmit frequencies are already the same.
Note that your dealer may have mode provision for
“Talk Around” channels by programming “repeater”
and “Talk Around” frequencies on two adjacent chan-
nels. If so, the key may be used for one of the other
Pre-Programmed Functions.
Note: The Talk Around feature does not activate on
the Simplex Channel.

always needed.
The Transmit Battery Saver helps extend battery life
by reducing transmit power when a very strong signal
from an apparently nearby station is being received.
Under some circumstances, though, your hand-held
radio may not be heard well at the other end of the
communication path, and high power may be neces-
sary at all times.
