during which all control uttons/kno s should e operated a few
times to avoid the accumulation of salt residue; wipe the housing
with a towel efore opening.

the rear part of the housing removed from its groove with the O-
ring remover and inspected for damage. Also check that the O-ring
retains its original circular shape; never stretch the O-ring
excessively or remove it with a sharp o ject. The O-ring groove
should e cleaned to ensure it is free from any salt deposit or
