Obtain the AdJ-O- screen (see Section 5.2.3) and keep
selecting ‘No’ to step through the subsequent screens to
obtain the AdJ-C- (for Toxic 1) or AdJ-H- (for Toxic 2)
screen. Alternatively, the AdJ-C- screen is obtained
subsequent to adjusting the explosive very high alarm
setting.

are to be adjusted. However, the procedure is the same
for both channels.

Select Yes to obtain the -C-Hi screen indicating the
current Toxic 1 instantaneous high alarm trigger level.
(3)
Make the required changes to the Toxic 1 high alarm
setting and then press the calibration button to step on
to the -C-Hi2 screen indicating the current Toxic 1
instantaneous very high alarm trigger level. (The following
illustration shows, as an example, the Toxic 1 very high
alarm as having been disabled).
