Resetting and Silencing Alarms

 You can set the GX-2003’s gas alarms as latching or self-resetting 
alarms (see “Updating the Alarm Latching Setting” on page 62).

• Self-resetting alarms (ALARM LATCHING set to OFF)

Self-resetting alarms automatically shut off and reset when the gas 
reading falls below (or rises above for an oxygen low alarm) the 
alarm setting. You cannot silence or reset self-resetting alarms.

• Latching alarms (ALARM LATCHING set to ON)

You can set latching alarms with or without Alarm Silence (see 
“Updating the Alarm Silence Setting” on page 62).

With ALARM SILENCE On and ALARM LATCHING On:

When the GX-2003 goes into gas alarm, press the RESET SILENCE 
button to silence the buzzer. If the gas concentration was still above
