MT10 Instruction for Use - EN

3. Operating instructions

This instrument is equipped with a real-time clock. Before use, please set the date & time to local
values in order to ensure that test data and calibration status are correctly identified.
Careful handling of instrument whenever in contact with patient should be of high priority. Calm and
stable positioning while testing is preferred for optimal accuracy.
3.1 Installing & replacing batteries
The MT10 may be powered from Alkaline 'AA' / LR6 batteries (e.g. Duracell MN1500) or rechargeable
Nickel-Metal Hydride (NiMH) batteries. Four batteries are required.
If the MT10 is to be used infrequently we recommend alkaline cells are fitted. NiMH batteries have a
high self-discharge rate and are likely to need recharging if left unused for several weeks. To fit the
cells remove the battery compartment cover on the base of the MT10. Fit the cells as indicated inside
the battery compartment.
Batteries should only be changed outside the patient environment. The operator should not touch the
battery connectors and the patient simultaneously.
You must set which type of cell is fitted in the CONFIGURATION menu. By default this is set to
ALKALINE. To change the setting select CONFIGURATION from the main menu and scroll to
BATTERY TYPE as described later in this manual.
A battery state indicator is shown in the top right corner of the display (except when showing test
results). This shows the battery state as a progressively emptying battery. The batteries should be
replaced when the symbol has an ! in front of it, or when advised to do so at switch-on. Removing the
batteries does not affect the configuration, the contents of the database, the calibration settings or the
results of the last test.
Remove the batteries if the instruments will not be used for some time.
