This alarm condition is also triggered when the oxygen concentration at
the point of analysis falls below 18% (Reference: ISO 7767 standard).
For safety reasons, the audible alarm cannot be silenced until the alarm
condition is resolved.
CAUTION: DURING NORMAL USE, ALARM CONDITIONS SHOULD
NOT BE OVERRIDDEN BY ACTIONS SUCH AS HOLDING
THE ALARM SILENCE KEY DEPRESSED OR REMOVING
THE BATTERIES. THE CAUSE FOR THE ALARM CONDI-
TION SHOULD FIRST BE RESOLVED.
CAUTION: WHILE HOLDING DOWN THE ALARM SILENCE KEY MAY
MOMENTARILY SILENCE THE ALARM BUZZER, AUDIBLE
ALARM WILL RETURN UPON DISENGAGING THE ALARM
SILENCE KEY. HOLDING THE KEY FOR LONGER DURA-
TIONS WILL INITIATE THE “STUCK KEY” ALARM, WHICH
CAN BE DEACTIVATED ONLY VIA REMOVING THE BAT-
TERIES FROM THE ANALYZER. ANALYZER SHOULD BE
RECALIBRATED UP ON REPOWERING THE ANALYZER.
NOTE: THE ALARM SILENCE KEY DOES NOT PLAY ANY ROLE IN
THIS VERSION OF THE ANALYZER. IT IS DESIGNED IN
FOR ANY POSSIBLE FUTURE PRODUCT MODIFICATION.
