Controls and Features
Power On/Off
To turn the Pro300 on, press the PWR
button on the left side of the top case.
When you turn the Pro300 on, it goes
through a sequence of alerts.
If you prefer, you may program your
Pro300 for a shorter power-on sequence.
See the Programming section for details.
Voice
The Pro300 has our Digital Voice
feature, which provides a digital voice
announcement of the band being detecting.
If you prefer, you can turn the Digital
Voice feature off in programming. See
Programming section for details.
Power-on indication
After Pro300’s start-up sequence is
complete, the alphanumeric display will
show Highway, City, or AutoScan to indicate
which sensitivity mode is selected.
If you prefer, you can select alternate
power-on displays. See the Programming
section for details.
AutoMute
Your Pro300 has our patented AutoMute
feature. After Pro300 alerts you to a radar
encounter at the volume you have selected,
the AutoMute feature will automatically
reduce the volume to a lower level. This
keeps you informed without the annoyance
of a continuous full-volume alert.
If you prefer, you can turn the
AutoMute feature off. See the Programming
section for details.
Volume / Mute Button
To adjust the alert tone volume, press and
hold the Volume/Mute bar located on the
top case.
The Mute button, located on Pro300’s
top case, allows you to silence the audio
alert during a radar encounter.
To mute the audio for a single specific
signal, briefly press the Volume/Mute
button. After that radar encounter has
passed, the mute will automatically reset
and the audio will alert you to the next
encounter.
Highway / AutoScan / City Switch
The City button selects Pro300’s sensitivity
mode. We recommend the AutoScan mode
for most driving.
Pro300’s AutoScan mode provides
long-range warning, with minimum false
alarms. In this mode, Pro300’s internal
computer continuously analyzes all
incoming signals and intelligently adjusts
the sensitivity.

You can also select conventional
Highway and City modes. When driving in
urban areas where annoying X-band
intrusion alarms and door openers are
common, City mode can be engaged to
lower X-band sensitivity and reduce X-band
alerts. Full sensitivity is maintained on all
other bands. You can customize Pro300’s
City mode sensitivity. See the Programming
section for details.
Brightness Button
Pro300’s BRT button selects the brightness
of Pro300’s display. There are four settings:
Maximum, Medium, Minimum, and Dark.
Press the BRT button to select your
preferred brightness.
Dark Mode
When you select the Dark mode with the
BRT switch, Pro300 changes to a very
inconspicuous power-on indication: a very
BRT AD, HD, or CD. (In this display, the A, H,
or C indicates AutoScan, Highway, or City,
and the D indicates Dark.)
When Pro300 is in the Dark mode, the
display will not show visual alerts when
Pro300 detects signals. Only the audible
alert will tell you of detected signals.
Audible Alerts
For Radar signals:
Pro300 uses a Geiger-counter-like
sound to indicate the signal strength and
type of radar signal being encountered.
When you encounter radar, a distinct
audible alert will sound and occur faster as
the signal gets stronger. This allows you to
judge the distance from the signal source
without taking your eyes from the road.
Each band has a distinct tone for easy
identification.
X-band = chirping tone
K-band = buzzing tone
Ka-band = double-chirp tone
For Laser signals:
Since laser signals are a possible threat
no matter how weak, Pro300 alerts you to
all laser signals with a full laser alert.
For Safety signals:
Pro300 will alert you to these signals
with a double-buzz tone (and digital voice
if programmed) with a corresponding text
message. A complete listing of the text
messages is on page 23.
