Control Buttons
Two control buttons, AIR and POWER MODE are located below the LCD.
Alarm LEDs
Five sets of red alarm LEDs (light emitting diodes) around the edge of the case alert you to gas,
low battery, and failure alarms.
Buzzer
One solid-state electronic buzzer is located inside the case. Sound exits the case through a hole in
the middle front of the case. The buzzer sounds for gas alarms, malfunctions, low battery voltage,
and as an indicator during use of the GX-3R Pro’s many display and adjustment options.
Vibrator
A vibrating motor inside the GX-3R Pro case vibrates for gas alarms, unit malfunctions, and as an
indicator during normal use of the various modes of the GX-3R Pro.
NOTE: If STEALTH is set to ON, the vibrator only functions when VIBRATION in the
STEALTH Gas Select Mode item is set to ON. See “Stealth and Vibrator Settings
