NOTE: The Alert LED utilizes a special tri-color Light Emitting Diode module
that mixes light from red, green and blue LED elements to produce thou-
sands of different colors. Eight pre-defined color settings are available for
use in object menus.
LED COLOR: 0
is normally used for “all colors
off”, or no Alert LED display.
NOTE: Slight variations to LED colors are a normal part of the manufactur-
ing process. You may notice these variations when using the White LED
color setting (
LED COLOR: 0
), or when comparing one PSR-310 to an-
other. You can compensate for these slight variations by fine-tuning the Red/
Green/Blue (RGB) LED settings for each color. See the COLOR settings in
the GLOB menu in Detailed Menu Reference section at the end of this man-
ual.
Audible Alarm and ALERT LED Settings
Each object you create has the following ALERT LED and Audible Alarm set-
tings:
LED Mode: Solid
or
Flash
controls whether the LED remains on
solid or flashes when the object is active.
LED Color: 0-7
sets the color of the LED. By default, color 0 is used
for LED off. You can change the LED colors in the Global Settings menu.
Latch LED
keeps the LED on after activity on the object is finished. This
is useful in cases where you need to know if an object was active while you
were away from the scanner.
Backlight: Off, On, Flash
controls whether the backlight re-
mains off, comes on solid or flashes when the object is active.
Alarm: None, Chirp, Hi-Lo, Alert, Ring,
2-Chirp, Fast Hi-Lo, DTMF #
are used to set audible alarms
that play each time activity is found on the object.
ALERT LED with Audible Alarm Examples
Here are some examples of when you may wish to use the ALERT LED with
Audible Alarm capability:
• You have programmed a Talkgroup Wildcard in for a trunked radio sys-
tem you monitor in order to find new talkgroups. You can use an Audible
Alarm to alert you when the radio receives a wildcard hit, and turn on the
backlight so that you can read the display and operate the keypad to
save or lock out the new talkgroup.
• You have programmed your favorite amateur radio repeater in and wish to
be alerted when a QSO begins. You can use an Audible Alarm with one of
the shorter alarms (Chirp, 2-Chirp, Fast Hi-Lo or DTMF #) to provide this
indication without covering the traffic in the QSO.
