When the MCX doesn't work properly
or doesn't work at all, it is
recommended to return the unit to one
of the Unomat Service Centers or to
your local distributor after you have
checked the following;
Most of the problems with portable
instruments are related to power
supply defects, blown fuses or
displaced connectors.
The unit doesn't work at all.
1. When normally line powered,
change to battery operation to
check the line adaptor.
2. When normally battery powered,
check the contact springs for
corrosion and spring force.
3. Check total battery voltage with a
voltmeter. Alkaline should read
around 9 Volts and NiCd's should
read around 7.2 Volts when new
or fully charged.
4. Open the MCX as described in the
previous paragraph and check
whether the PCB interconnecting
plugs are still in position.
