This section discusses the basic maintenance and checks that an operator can
perform on the MTD200 MPEG Test Decoder,
The instrument requires no regular maintenance. Generally, maintenance is
confined to cleaning the instrument and changing the battery. Make sure that air
inlets and outlets are not blocked and clean them at regular intervals.
The outside of the instrument can be cleaned with a soft, lint–free cloth or a
brush. For heavier contamination, use spirit or mild soap suds for cleaning.
CAUTION. To prevent damage to front-panel labels or plastic parts, do not use
solvents such as nitro thinners or acetone.
Any dust collected inside the instrument should be removed at regular intervals
to ensure unimpaired cooling (approximately every 1 to 2 years, depending on
the daily on–time of the equipment and the amount of dust in the environment).
Storage temperature of instrument:
– 40 to +70 C.
When stored for an extended period of time, protect the instrument from dust.
These instructions are for personnel who are familiar with servicing the product.
If you need further details for disassembling or reassembling the product, contact
your nearest Tektronix, Inc., Service Center or Tektronix Factory Service for

WARNING. To prevent injury, avoid short circuiting or charging the battery, since
this can cause the battery to explode. Do not open discharged batteries; dispose
of them as hazardous waste.
The instrument uses a lithium battery for storing the selected status and for
operation of the real–time clock. The battery has a lifetime of approximately
five years and should be replaced as required (for example, after a long storage
period at high temperatures). Replace the discharged battery by one of the
same type.
