Activating the Detector
Self-Test Pass
If the detector passes the self-test, it enters normal operation and 
displays the ambient gas readings.
The detector begins recording the peak (MAX) gas exposure and calcu-
lating the short-term exposure level (STEL) and time-weighted average 
(TWA) exposures.
Self Test Fail
If a sensor fails, FAIL flashes above that sensor on the normal operation 
screen. For possible problems and solutions, refer to Troubleshooting
.
Battery Test
The batteries are tested when the detector is activated and continuously 
thereafter. The battery power icon displays continually during normal 
operation. If battery power is low,   flashes.
Datalogger Operation (Optional)
a Caution
Do not remove the battery pack while the detector is 
activated. Doing so will prevent the datalogger from 
logging correctly.
Datalogger operation is automatic and requires no settings. During 
normal operation the card is tested every 20 seconds.
Note
The MMC/SD card icon (S) displays continuously on the LCD 
when the card is inserted. The card is not required for opera-
tion; however, if the card is not inserted the detector will not 
record data.
