Power ON/OFF Key
This key is used to turn on or off. The blender will continue to function and deliver mixed gas with
display turned to OFF. When the ON/OFF key is pressed once, the Bird Sentry blender will start to
display the oxygen concentration and the keypad is activated. If the ON/OFF key is pressed again,
the Bird Sentry blender reverts to the display power off mode.
E
Lock Key
Pressing the LOCK key will unlock the keypad and cause the LOCKED icon to disappear from the
LCD readout. The Bird Sentry blender can then be calibrated and alarm settings can be changed if
desired. If no other keys are pressed within 10 seconds, the LOCKED icon will reappear and the
unit will revert to the LOCKED mode. When the unit is in the unlocked state, pressing the LOCK
key will also cause the LOCKED icon to reappear.
