To clean the instrument, wipe it gently with a soft cloth moistened
with water or mild detergent. Never use solvents such as benzene,
alcohol, acetone, ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
• If the instrument seems to be malfunctioning, confirm that the
cables are not open circuited before contacting your dealer or
Hioki representative.
• When sending the instrument for repair, remove the batteries and
pack carefully to prevent damage in transit. Include cushioning
material so the instrument cannot move within the package. Be
sure to include details of the problem. Hioki cannot be responsi-
ble for damage that occurs during shipment.
• When transporting (moving) the instrument or an apparatus
incorporating the instrument, take appropriate measures to pre-
vent the instrument protruding (by taping the front, for example).
• The instrument contains a built-in backup lithium battery, which
offers a service life of about five years. If the date and time devi-
ate substantially when the instrument is switched on, it is the time
to replace that battery. Contact your dealer or Hioki representa-
tive.
