Calibrating the Oxygen (O
) Detector
2
Every 30 days when the O
detector is due to be calibrated, the LCD flashes

CAL and the detector life-remaining value to indicate that calibration is due.
To calibrate the O
detector, complete the following:
2
1. Calibrate the detector only in a normal atmosphere (20.9% O
free of hazardous gas.
2. Press and hold C for approximately 3 seconds.
3. The detector emits one beep, one flash, and displays the following
screen:
Successful Calibration: The detector emits one vibration and one
extended beep to indicate that calibration is successful.
Unsuccessful Calibration: If the detector does not beep or vibrate after a
calibration, repeat steps 1 and 2 again. If the second attempt is
unsuccessful, contact

Technologies.
Gas Event Data Transmission
The detector stores the last ten alarm events. The recorded data includes
the
•
serial number,
•
detector life-remaining values (months/days/hours),
•
self-tests that have been performed,
•
total number of events that have occurred,
•
event type,
•
duration of all events encountered,
•
gas type,
•
alarm level(s) (ppm or %),
•
time elapsed since the alarm occurred (days/hours/minutes), and
•
duration of the alarm (minutes/seconds).
Two options are provided to transmit the gas event data: 1) Transfer data to
a PC using an IR data link or 2) Print the data using the handheld IR printer.

5. While data is being transmitted,
countdown timer displays as a percentage value (70%) indicates how
much data remains to be transmitted.
