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.
NOTICE Remove the batteries if the instruments will not be used for some time.
3.2 Controls and indicators
Press the On/Off key momentarily to turn the MT10 on (refer to the diagram below).
No warm-up time is required, although a short diagnostic routine will run for a few seconds. During this
time the internal pump will operate. To switch off, again press the On/Off key momentarily
Press the On / Off key momentarily to turn the MT10 on or off.

3.3 The Probe
The small holes through the MT10 probe tip must be kept clear. If these become blocked a warning
message will be displayed. The tip must be removed and cleaned or replaced.
To remove the tip, unscrew the nose cone and pull the tip off the probe boss. A small seal will be
found in the base of the probe tip. This should be examined and replaced if it is damaged.
When replacing the tip, ensure that the seal is correctly inserted with its flat aligned with the flat on the
probe tip. Push the probe tip over the boss and replace the nose cone. Make sure that the nose cone
is screwed home firmly but do not over-tighten. Do not use any tools to tighten the nose cone.
After replacing the tip a Daily Check should be carried out.

NOTE:
It is advised not to transfer several records to
the PC at the same time (Diagnostic suite) as
the system is not prepared for this.
If you select ”Send records to PC” and transfer “all
records”/”Unsent records”, you get the message in
the Diagnostic Suite view: “Overwrite data with
new transferred data”?
Hence, all the records will be sent to the
dedicated folder on the PC and the Diagnostic
Suite will ask if you want to overwrite the current
data on the screen. So it is recommended to send
the individual records by selecting “List records”
(in “Data Management”) and select the preferred
record. (NB: Remember to start Diagnostic
Suite/Imp Module before transferring the record).
NOTE:
Please be aware that when connecting the USB IR receiver and the Sanibell II printer at the same
time, the printer may start printing out nonsense data from the PC because the Infrared receivers may
interfere with each other. However, it does not happen often that users will send data to their PC as
well as print out the data on the wireless printer. IF the scenario occurs, please see that the two IR
windows on these devices are not pointed directly at each other.
