Servicing. Do not attempt to service the
instrument yourself; opening or removing
covers can expose you to dangerous voltage
and other hazards. Please refer all servicing
to qualified service personnel as opening or
removing covers may result in fire, electric
shock or equipment damage.
If, for some reason, you need to return your
instrument, please use either the original
transport box or one of equivalent strength.
22]
Damage requiring service. Unplug the instru-
ment from all connections and refer servicing
to qualified service personnel under the fol-
lowing conditions:
- When any connector is damaged, including
mains plug.
- If liquid has been spilled or objects have fallen
into the instrument.
- If the instrument has been exposed to rain or
moisture.
- If the instrument does not operate normally
(follow operating instructions).
- If the instrument has been dropped or dam-
aged in any way.
- When the instrument exhibits a distinct
change in performance. This indicates a need
for service.
If the instrument begins to emit smoke,
smells like something is burning or makes
strange noise, disconnect all power connec-
tions immediately and contact your dealer
for advice.
23]
Replacement parts. When replacement parts
are required, be sure the service technician
has used replacement parts specified by the
manufacturer or that they have the same
characteristics as the original parts. Unau-
thorized substitutions may result in fire,
electric shock, or other hazards.
24]
Safety check. Upon completion of any repairs
to the instrument, ask the service techni-
cian to perform safety checks to determine
that the unit is in safe operating condition.
Except for visual inspection and function
tests, dielectric strength test and Protective
Ground (Earth) & Bonding impedance tests
are required for safe operation after service.
Refer to manufacturer’s production test
instructions. Neglecting these measurements
after service may result in fire, electric shock,
or other hazards.
25]
Cleaning. Unplug the instrument before
cleaning it. Do not use liquid cleaners or aero-
sol cleaners. Use only a damp cloth for clean-
ing. Periodically clean the instrument with a
soft cloth. Stubborn stains may be removed
with a cloth lightly dampened with a mild
detergent solution.
Periodically clean the area around the mains
plug and at all other connectors.
