1.4.1 Security
beep
The ToxiPro includes a security beep that can
be enabled or disabled with BioTrak software
through the PC’s IrDA port. If the security
beep is enabled, the ToxiPro will emit a short
beep coupled with an LED flash at a specific
interval to remind the user that the instrument
is active.
1.4.2 Latching
alarms
The ToxiPro includes latching alarms that can
be enabled or disabled with BioTrak software
through the PC’s IrDA port. With the alarm
latch enabled, the audible and visible alarms
will continue to sound even after the
atmospheric hazard has cleared. To turn the
alarm off once the hazard is no longer
present, simply press the MODE button.
1.4.3 Silence warning alarms
The ToxiPro’s audible and vibrating (if so
equipped) alarms can be turned off during an
alarm condition by pressing the MODE button
if this function has been enabled with BioTrak
software. The visual warning alarm light and
readings will continue to indicate the alarm.

PC (polycarbonate) case with TPE (rubber)
overmold.
Figure 1: Exterior front view.
Front face:
The front face of the instrument
houses the LCD display, MODE button,
sensor port, LED alarm and audible alarm
port.
LCD display:
The liquid crystal display (LCD)
shows gas readings, messages and other
information. A built-in, manually-activated
backlight allows the display to be read even in
low light conditions.
Visual alarm (LED) /

A bright red
LED (Light-Emitting Diode) alarm light
provides a visual indication of the alarm state.
The LED also functions as the IrDA port.
MODE button:
The large push-button on the
front of the instrument is called the MODE
button. The MODE button is used to turn the
ToxiPro on and off, to turn on the backlight, to
view the MAX, STEL (if enabled) and TWA (if
enabled) screens and to initiate the automatic
calibration sequences.
Sensor port:
The sensor port is located at
the upper left corner of the instrument. A filter
prevents unwanted contaminants from
entering the sensor.
