7. Turning The ToxiRAE Pro On
To turn the ToxiRAE Pro on, press and hold [MODE] for 3 seconds.
Caution: The alarm buzzer is very loud. During startup, you can mute most of the sound
by holding a finger over the alarm buzzer port.
Note: Never put tape over the alarm buzzer port to permanently mute it or otherwise limit
the loudness of the buzzer.
1. When the ToxiRAE Pro turns on, the buzzer, vibration alarm, and LEDs are tested.
The firmware version is shown in the display (for example, “V1.00” indicates
firmware version 1.00).
2. A battery test is performed. If the battery has sufficient charge, then the next step is a
self test of the system.
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 shuts off. You
must charge the battery before you can use the instrument.
3. Self-testing is performed by the ToxiRAE Pro.
Note: If one of the following error messages is displayed, shut off the ToxiRAE Pro
by pressing [MODE]:
• Sensor error!
• Wrong sensor!
If any of the following error messages occurs, you can either shut off the instrument
by pressing [MODE], or continue to the next startup test by pressing [Y/+]:
• Real time clock error!
• Memory error!
• Sensor changed!
For any of these error types, try restarting the instrument. If the error message appears
again after five more attempts to restart the instrument, consult the distributor from
whom the instrument was purchased for technical support.
