8-1 Repair service at customer's expense
1. Before requesting our repair service, check that:
• the built-in fuse is not blown out;
• the built-in dry cells have not run out; and
• the test leads are not broken.
2. Repair service period
Repair components will be retained in stock for a minimum period of 6 years after the
discontinuance of manufacture. We accept your repair request during this period. However, note that
some semiconductors may become unavailable earlier because of difficulties in purchasing them.
3. Repair service charge
If excessively large voltage is applied exceeding the function of the overload protection circuit
and damages the LSI (malfunction), the circuit boards (burned patterns), or any other expensive
main component, the repair service charge may exceed the purchase cost. In such a case, it is
recommended that a new product be purchased. The transportation charges for sending your
PC20TK to us and returning it to you are to be borne by you along with the repair charge.
4. Address for sending your PC20TK
In order to ensure the safe transportation of the PC20TK, place it in a box having volume of at
least 5 times the product size and fill the space with sufficient pad or filler. Mark the box as
"Product to be repaired."
