Insertion & Removal
7
Insertion
• Make sure the eartip is clean.
• Pull the ear up and out
while inserting.
• Twist and push gently until the
eartip seals in the ear canal.
• When using 3-flange eartips,
moistening may ease insertion.
• When using foam eartips: Roll
down or compress the foam
eartip before inserting. Hold
the eartip in place for about
5 seconds while foam expands
to create a tight seal in the
ear canal.
• When using glider eartips
no compression is needed;
simply push into the ear.
Removal
• Remove the device with
a slow twisting motion.
• After removal, place earplugs
in a clean, protective case.
