Troubleshooting - cefar IFC Manual De Instrucciones

• Switch off stimulation before remo-
ving the electrodes from the skin. If
an electrode comes off, switch off
stimulation before picking it up.
Electric stimulation in the fingers is
uncomfortable, but not harmful.
• Exercise caution when using electro-
des smaller than 50 mm in diameter
or 50 x 50 mm square, as they can
cause burns. The smallest Cefar
electrodes recommended are 50 mm
round electrodes and 40 x 60 mm
oval electrodes.
• Use only Cefar accessories with the
CEFAR IFC.
• Observe all instructions in this
manual when using the CEFAR
IFC.
• Check your equipment before use.
• Never open the battery cover during
stimulation.
• This stimulator meets the requi-
rements of MDD 93/42/EEC,
including the EMC requirements.
However, this does not guarantee
that the equipment cannot be affec-
ted by or cause electromagnetic dis-
turbances.
• If the stimulator has not been used
in a long time (three months or
more), non-rechargeable batteries
should be replaced before use.

TROUBLESHOOTING

Stimulation doesn't feel the way it
usually does
Make sure that all settings are correct
and that the electrodes are correctly
placed.
Stimulation is uncomfortable
• Your skin is irritated. For skin-care
advice, see the Safety Precautions
section.
• The electrodes are too old and need
to be replaced.
The current is weak or nonexistent
• Check if the batteries need to be
replaced/charged; see the Batteries
heading.
• Check that the electrodes are not
touching.
• If the closed circuit is broken, for
example due to a broken cable, the
amplitude to that channel switches
off automatically, and 0.0 mA blinks
on the display. You can check for
cable breaks by holding the ends of
the cables together and then increa-
sing the amplitude of the channel
to about 15 mA. If the amplitude
disappears and 0.0 mA blinks in the
display, the cable needs replacing.
Note: Never increase the amplitude
above 20 mA when you check for
cable breaks; this can damage the
stimulator.
• Excessive resistance is indicated by
the amplitude dropping to 0 mA
and 0.0 mA blinking in the display.
