Alarm Silence; All Mute; Numeric Display - GE TruTrak+ 3900 User Manual

1 Alarm silence button
This button has two functions:
• 120-second alarm silence—activated by a single press.
• Continuous all mute—activated by three quick presses (if the all-mute
feature is enabled). Press once to deactivate.

Alarm silence

When an active alarm condition exists, press this button to silence the audible
portion of the alarm for 120 seconds. The flashing red or yellow alarm light
becomes a steady light. If an alarm condition still exists after 120 seconds, the
audible tone and flashing light resume.
Exceptions: Both NO SENSOR and SENSOR OFF audible alarms will not be
activated until after the unit obtains a valid signal. The same conditions apply
to an active audible alarm for NO SENSOR, SENSOR OFF, or SENSOR
FAILURE that has been silenced; i.e., once the sensor alarm condition is
acknowledged by silencing the audible alarm, a new audible alarm will not
sound until the condition has been cleared and the unit obtains a valid signal.
NOTE: Pressing the alarm silence button produces 120 seconds of silence,
regardless of other alarm conditions that may occur during this 120-second
interval, except for the SYSTEM FAILURE, CONNECT UNIT TO LINE
POWER, and BUTTON STUCK alarms.

All mute

To continuously silence any alarm that can be silenced, press the alarm
silence button three times within three seconds. After you have activated all
mute, the all mute icon flashes between the SpO
settings on the right side of the screen display. (On Japanese menu screens,
the icon flashes at the upper right beside the first menu option.) When an
alarm condition occurs, the alarm button light flashes and the alarm message
appears on the waveform display but no audible alarm sounds.
When all mute is active, press the alarm silence button once to deactivate this
feature and enable all audible alarms.
The ability to mute all alarms continuously can be disabled; see SETTINGS,
ALL MUTE in chapter 2.
