6. Push the CAL key. The CAL LED will light solid. When the unit has taken the readings using
the second calibration gas, the CAL LED will flash a two-pattern flash or a three-pattern
flash. A two-pattern flash equals a valid calibration, three-pattern flash equals an invalid cali-
bration.

the new calibration values are not within the parameters, the DIAGNOSTIC ALARMS LEDs
will indicate an alarm.
