PRECAUTIONARY MEASURES
Warning
• Warning! Users with implanted electronic equipment, such
as pacemakers and intracardiac defibrillators, must not use
the CEFAR MYO XT/CEFAR ACTIV XT. Pregnant women
should not use the CEFAR MYO XT/CEFAR ACTIV XT
during the first trimester, and should always consult a doctor,
midwife or physiotherapist prior to use.
• Do not stimulate on the front or sides of the neck, since a
drop in blood pressure can occur.
• Do not use the CEFAR MYO XT/CEFAR ACTIV XT if you
are connected to high-frequency surgical equipment, since this
may cause burn injuries on the skin under the electrodes, as
well as problems with the stimulator.
• Observe caution when using the CEFAR MYO XT/CEFAR
ACTIV XT in the immediate vicinity of cellular phones that
are switched on.
• Do not use the CEFAR MYO XT/CEFAR ACTIV XT in the
direct vicinity of shortwave or microwave equipment, since
this may affect the output power of the stimulator.
• Keep out of reach from children.
Note
• The stimulator should only be used with skin electrodes
intended for nerve and muscle stimulation. See electrode pack-
age for instructions of use.
• The electrodes should only be placed on healthy skin. Avoid
skin irritation by ensuring good contact between electrodes
and skin. Hypersensitivity can occur in rare cases. If skin
irritation should occur, stimulation with the CEFAR MYO XT/
CEFAR ACTIV XT should be temporarily discontinued. If
condition persists, seek medical advice.
• Switch off stimulation before removing the electrodes from the
skin. If an electrode comes off, shut off the stimulation before
picking it up. Getting electrical stimulation through the fingers
is unpleasant but not harmful.
• Exercise caution when using electrodes smaller than 14 cm², as
the current density in some cases exceeds 2 mA rms/cm² and
increases risk for burn injuries.
• Be careful with stimulating in the heart region.
• CEFAR Medical AB does not take any responsibility for any
electrode placements other than recommended.
• Muscle soreness may occur after stimulation with CEFAR
MYO XT/CEFAR ACTIV XT, but usually disappears within a
week.
• Only Cefar accessories should be used with the CEFAR MYO
XT/CEFAR ACTIV XT.
• Use the CEFAR MYO XT/CEFAR ACTIV XT only as stated
in the user’s guide.
• Inspect the equipment prior to use.
• Never use more than one stimulator at the time.
• Never open the battery lid during stimulation.
• The stimulator meets the requirements of MDD 93/42/EEC,
including the EMC requirements. This, however, is no
guarantee that the equipment will not be affected by
electromagnetic disturbances.
• If the stimulator is not used for some time (approximately
3 months), the non-rechargeable batteries should be
removed from the stimulator.
