CAUTION
Always handle earphones with care. Neither drop them nor permit
them to be squeezed together. Severe mechanical shock may change their operating
characteristics and require their replacement.
IMPORTANT: Always clean and maintain your earphone cushions, for hygiene
purposes. Check periodically for cracking or signs of wear. Cleanse cushions
daily or after each use (depending upon population being tested). Use a
solution of diluted alcohol or mild soap and water, taking care not to get any of
the cleaning solution into the earphone speaker. Use earphones only when
completely dry. Insert the earphone cords between the earphone cushions
during storage to prevent damage from mechanical shock.
