the sequence (PEAK).
If the button is pressed, the Bump Test is not performed, and the display reverts back to the normal

Short Term Exposure Limits (STEL page)
If the STEL alarm activates, leave the contaminated area immediately; the ambient gas concentra-
tion has reached the preset STEL alarm level. Failure to follow this warning will cause over-exposure
to toxic gases and persons relying on this product for their safety could sustain serious personal
injury or death.
This page shows the average exposure over a 15-minute period.
When the amount of gas detected by device is greater than the STEL limit:
-
Alarm sounds, alarm lights flash.
-
Alarm LEDs flash
-
"STEL ALARM" message flashes.
To reset the STEL:
(1) Access the STEL page.
(2) Press the button.
The STEL alarm is calculated over a 15-minute exposure.
