Resetting Alarms
The GX-82A can be set for latching or self-resetting logic. Latching
alarms can not be reset until the gas concentration falls below the
alarm point. When the condition is corrected, press (SHIFT)/▼ to
reset the alarm. Self-resetting alarms will automatically shut off when
the concentration falls below the alarm point. (See USER OPTIONS.)
