*1 Olympus tested the compatibility of accessories with the WD compatible with
ISO 15883-1, 2. The drying temperature and the drying duration were 110°C
and 20 minutes, respectively
*2
.
*2 This value may not be the actual temperature of the accessories being
processed in the chamber, but it is a setting value for the WD. The drying
temperature for which Olympus confirmed material compatibility is 110°C as
the WD setting value. In the drying process, the temperature around the
product can be affected by various factors (e.g., chamber size, loading
amount, layout of instruments in the chamber).
