OPERATING INSTRUCTIONS
Before turning on the detector, move to an area
where the air is clear of all combustible gases,
smoke, perfume, alcohol and volatile organic
compounds (VOCs). If you activate the unit where
any of these substances is present, the instrument
will automatically calibrate to a non-zero gas
concentration baseline. This will produce inaccurate
(and potentially dangerous) readings and foster a
false sense of security.
To activate the PNG2000A, move the power switch
(Fig. 1, Callout 5) to the ON position. The instrument
will immediately sound a brief, rapid sequence of five
tones and begin a 15-second warmup period. During
this period, the three front-panel LEDs will flash
rapidly and repeatedly in order from bottom to top.
The warmup period ends when the detector sounds
two loud descending tones. To signal that the
instrument is ready to detect gas, the green LED
flashes about once every 7 seconds, accompanied
by two muted ascending tones.
