Disconnect the battery before removing sensor

the top or the cover is removed. Remove the top, the

SPECIAL NOTE
When the PGM-2000 or PGM-2020 multi-gas monitor is taken
out from the transport case and is turned on for the first time,
there may be some residual vapor trapped inside the detector
chamber. The initial toxic sensor readings may indicate a few
ppm. Make sure the area is free of toxic vapors before turning
the monitor on. After running the monitor for several minutes,
the residual vapor in the detector chamber should clear and
readings should return to zero.
