WARNINGS
Read Before Operating
The User’s Guide must be carefully read by all
individuals who have or will have the responsibility
of using, maintaining, or servicing this product.
The product will perform as designed only if it is
used, maintained, and serviced in accordance with
the manufacturer’s instructions.
CAUTION!
Never operate the monitor when the cover is
removed. Remove monitor cover and battery only
in an area known to be non-hazardous.
User Interface
The ToxiRAE 3’s user interface consists of the
display, LEDs, an alarm buzzer, and two keys,
[MODE] and [Y/+]. The LCD display provides
visual feedback that includes calibration or bump
request, sensor mode, and battery condition.
Turning The ToxiRAE 3 On
Press and hold [MODE]. The display shows “On” and
the sensor type, and then alarms and sensor are tested.
Note: If the sensor is depleted or does not check out
satisfactorily, an error message of “E01” flashes on
the display. The ToxiRAE 3 should not be used. (Shut
off the ToxiRAE 3 by pressing and holding [MODE]
until you see the countdown and the display shows
“oFF.”).
Once the countdown is complete, a battery icon that
indicates battery condition. “OK” is displayed below
the battery icon, and the reading is also shown (for
example 0 ppm). The ToxiRAE 3 is now in Normal
Mode and is ready for use.
Turning The ToxiRAE 3 Off
Press and hold [MODE]. In 2 seconds, a 5-second
countdown to shutoff begins. You must hold your
finger on the key for the entire shutoff process. If
you remove your finger from the key during the
countdown, the shutoff operation is canceled and
the ToxiRAE 3 continues normal operation.
When you see “oFF,” release your finger from the
[MODE] key. The ToxiRAE 3 is now off.
Low Battery Warnings
•When the battery’s charge is low, the battery
symbol flashes once per second and “bAt”
flashes once per minute. The buzzer and vibrator
alarm once per minute.
•When the battery reaches a critically low charge,
the battery symbol flashes once per second and
“bAt” flashes once per minute, plus the buzzer
sounds once per minute.
•When the battery is dead, the buzzer sounds
once per second for the last minute and then
shuts off. The display shows “oFF.”
Important! Do not operate the ToxiRAE 3 again
until its battery has been replaced.
WARNING!
To reduce the risk of ignition of hazardous
atmospheres, replace battery only in areas
known to be non-hazardous. Consult User’s
Guide for battery replacement procedure.

Programming Mode
The ToxiRAE 3 must be in programming mode to
perform calibrations, unless you use AutoRAE Lite.
Turn on the ToxiRAE 3. Once it has been through
its startup, enter Programming Mode. Note: This is
not available in Disposable mode.
1. Press and hold both [MODE] and [Y/+] until
you see the password screen, “000.”
2. Enter the password (the default is 111) by
pressing [Y/+] to increase the number,
followed by pressing [MODE] to advance to
the second digit. Follow this procedure until
there are three “1”s.
3. Press and hold [MODE] until you see the “Zero
Cal?” screen.
Zero (Fresh Air) Calibration
With the ToxiRAE 3 on and in Programming
Mode, follow this procedure:
1. Press [Y/+]. A countdown starts and “CAL”
blinks. This indicates that zero calibration is
taking place.
2. When the countdown reaches “0,” the display
alternates between “0” and “dn” (for “done”).
Upon completing a zero calibration, the ToxiRAE 3
automatically advances to the span calibration
menu.
Note: Interrupt zero calibration during its
countdown by pressing either key. When you do so,
the display shows “no.”
Span Calibration
Connect the gas cylinder, flow regulator, and
Calibration Adapter to the ToxiRAE 3 and start the
gas flow.
With the ToxiRAE 3 on and Programming Mode,
and with the Span Cal menu screen showing:
1. Press [Y/+]. A countdown starts and “CAL”
blinks. This indicates that span calibration is
taking place.
2. When the countdown reaches “0,” the display
alternates between the concentration in ppm
and “dn” (for “done”).
Note: Interrupt span calibration during its
countdown by pressing either key. When you do so,
the display shows “no.”
Bump Testing
RAE Systems recommends periodic bump testing.
1. Turn on the ToxiRAE 3 in Normal Mode.
2. Connect the calibration gas cylinder, flow
regulator, and Calibration Adapter to the
ToxiRAE 3 and start the gas flow.
3. Press [MODE] repeatedly until you see
“Bump” flashing in the display.
4. Check that the bump gas concentration is the
same as the gas cylinder’s concentration.
5. Press [Y/+] to start the bump test.
6. If the bump test is successful, the screen returns
to Normal Mode and resets the bump due day
icon on the screen.
Normal Mode Screens
Press [MODE] to step through screens showing
STEL, TWA, Peak, and Alarms.
To clear Peak, STEL, or TWA values, press [Y/+],
and you then see “CLr” accompanied by a flashing
“?”
•Press [Y/+] to clear the value.
•Press [MODE] to leave the value unchanged
and advance to the next screen.
In Peak, press [Y/+] twice to clear the Peak.
Using With AutoRAE Lite
To perform bump tests and calibration using an
AutoRAE Lite:
1. Start the ToxiRAE 3 and press [Y/+] until you
see “Ir.”
2. Follow the AutoRAE Lite’s instructions for
installing a gas cylinder and turning it on.
3. Place the ToxiRAE 3 in the AutoRAE Lite’s
dock.
