Replacing the Lithium Battery
The ToxiRAE II is shipped with its Lithium battery installed.
Change the battery when the low battery
symbol appears. When a battery needs
replacement, the alarm beeps and ashes once
a minute until a fresh battery is installed.
Just before the battery dies, “oFF” will appear
instead of the reading. The alarm will continue
to beep, ash and vibrate for a minute until the
battery is dead.

To exit Program Mode (Firmware version 1.7): Press the button
until “Pro” and “End” appear. Hold the button down for 5 seconds
and release. The ToxiRAE II is now in Monitor Mode.
