To avoid error conditions caused by dirty or worn SPA blocks, we
recommend that you perform the following preventive maintenance
procedures.
• Keep the SPA block covered when it is not in use.
• To prevent base adapters from contaminating the SPA block, store
them in an uncontaminated area.
• Each time you remove or replace a programming module, clean the
SPA block with a brush.
• Inspect the SPA block for dirt weekly. Perform the following steps to
clean the SPA block:
1. Blow filtered compressed air across the SPA block.
2. Mildly dampen a small section of a lint-free cloth with a DeoxIT
pen (Data I/O P/N 570-5500-901) and gently rub the dampened
cloth across all the pins on the SPA block.
3. Using a clean section of the lint-free cloth, gently wipe the surface
again.
