Basic Operation
4.1
Turning On
Press and hold the [ /↓] Key for 3 seconds, until the buzzer beeps and the red LED flashes. As
the unit powers on, it will go through a self-test and warm-up before the MUNI’s main reading
screen appears and it is ready for use. If a sensor is not warmed up, it will display “--" until it is
ready (usually 30 seconds or less).
CAUTION:
The alarm is loud. During startup, one can mute most of the sound by temporarily
holding a finger over the buzzer opening. Do not put tape over the buzzer opening as it
continuously mutes, causing a serious safety concern.
4.2 Turning Off
In normal reading mode, press and hold the [ /↓] key for a 5-second count down until the unit
displays ‘UNIT OFF’.
4.3 Active Sensor Displays
When one or more sensors is either not installed or turned off, the display shows only the
installed, active sensors.
4.4 Alarm Testing and Backlight
Under normal operation mode and non-alarm conditions, the audible (buzzer) alarm, vibration
alarm, LED, and backlight can be tested at any time by pressing Left [+/OK] once. Holding
down the [+/OK] key for more than 3 seconds repeats the alarm test for as long as the Left
[+/OK] key is held down.
The backlight can be turned on for one minute, to aid visibility in dark conditions, by pressing
Left [+/OK] once or by pressing Right [ /↓] and cylcing through the Main User Menu (these
methods apply only if the backlight is in Manual Mode, but not in Automatic Mode; see PC
Communication, Section 6.1)
WARNING!
If any of the alarms do not respond to this test, check the Alarm Settings using mPower Suite to
see if the alarms have been turned off. If any of the alarms is enabled but not functional, do not
use the instrument. Contact an mPower service center for technical support.
