Figure 2
1.7.8 Control Buttons:
Two control buttons, AIR and
POWER/MODE, are located below the LCD. The
functions performed by the control buttons are
summarized in the table in Figure 3.
They turn the CMS-4 ON and OFF. They control what is
displayed
on
the
LCD,
including
time,
gas
concentrations, as well as other messages. They also
allow for a fresh-air adjustment, change alarm points,
change the time, and calibrate the instrument.
NOTE: Important points to remember are:
1. The AIR button scrolls through items on the
menus much like a cursor. Once the menu
item is selected, use the POWER/MODE to
enter the selection into the microprocessor.
2. To reverse the direction of change (i.e. from
increasing to decreasing or vice versa):
a. Press and hold AIR.
b. Immediately press POWER/MODE
and then release both buttons.
NOTE: Each screen displays for 20 seconds. If you
do not press a button within 20 seconds, the CMS-4
automatically returns to Measuring Mode.
