The ToxiRAE Pro LEL 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.

User Interface
The ToxiRAE Pro LEL’s user interface consists of
the display, four LED lights, an alarm buzzer, and two
keys, [MODE] and [Y/+]. The LCD displays real-
time reading in specified measurement units, sensor
type, alarm type (when in alarm, including cal.
overdue), battery status, datalog (if on), and radio and
connection quality (if available).
Charging The ToxiRAE Pro LEL
Always fully charge the battery before use. Contacts on
the bottom of the ToxiRAE Pro LEL meet the cradle’s
contact pins, transferring power. While charging, the
LED on the cradle glows red. When the battery is fully
charged, the LED glows green.
Turning The ToxiRAE Pro LEL On
Press and hold [MODE] for 3 seconds. During
startup, the battery, buzzer, vibration alarm, and
LEDs are tested, and then the ToxiRAE Pro LEL
performs self-testing of its functions. When the
main measurement screen appears, the ToxiRAE
Pro LEL is ready for calibration or use.
Note:
If the battery is almost fully discharged, the
message “Battery too low! Needs charging.
Powering off!” shows in the display and the
ToxiRAE Pro LEL shuts off. You must charge the
battery before you can use the instrument.
Turning The ToxiRAE Pro LEL Off
Press and hold [MODE]. A 5-second countdown to
shutoff begins. You must continue pressing 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 Pro
LEL continues normal operation.
When the countdown beeps stop and you see “Unit
Off,” release your finger from the [MODE] key.
The ToxiRAE Pro LEL is now off.
