3.2 CLOCK BATTERY
An internal clock battery is mounted on one of the instrument’s printed circuit boards. This long-life
battery keeps settings in memory from being lost whenever the Li-ion battery or alkaline batteries
are removed. This backup battery should last approximately five years, and must be replaced by an
authorized mPower service technician. It is not user-replaceable.
3.3 DATA PROTECTION WHILE POWER IS OFF
When the instrument is turned off, all the current real-time data including last measured values are
erased. However, the logged data are preserved in non-volatile memory, so that even if the battery is
disconnected, the logged data will not be lost.
4. Instrument Operation
The NEO gives real-time measurements and activates alarm signals whenever the readings exceeds
preset limits. Prior to factory shipment, the instrument is preset with default alarm limits and the
sensor is pre-calibrated with standard calibration gas. However, the instrument should be tested and
the calibration verified before the first use. After the instrument is fully charged and calibrated, it is
ready for immediate operation.
The instrument works in different operation modes defined by the product model and factory setting.
When the unit is turned on, it enters User Mode, where basic users can only see and use a limited set
of functions. In Configuration Mode, which is password protected, advanced users can adjust various
settings. In some cases, Configuration Mode is not accessible on the instrument display and the
mPower Suite software must be used to change settings.

version and serial number.
