General Alarms
14.1. Manual Alarms Test
Under Normal Operation Mode and non-alarm conditions, the buzzer (audible alarm),
vibration, visible alarms, and backlight can all be tested anytime by pressing [Y/+]. If any
alarm does not respond, connect the MicroRAE to a PC running ProRAE Studio II and
check the alarm settings to make sure all alarms are enabled. If any alarms are enabled
but not functional, the instrument should not be used. Contact RAE Systems Technical
Support.
