gently slide it out.

2. Insert the nozzle into the earphone, aligning the dots so it
matches the keyed opening.
3. Place the threaded collar over the nozzle. After ensuring the
threads are properly engaged, use the nozzle key to gently turn
clockwise.
Caution:
There should be no resistance to turning the collar
until fully threaded into the housing. Check the following:
• The insert is fully seated in the nozzle.
• The nozzle is properly seated in the housing (dots
aligned).
4. Once you are certain that the nozzle is properly seated and the
collar threaded all the way into the earphone housing, use the
key to tighten the collar just enough to ensure it will not loosen
during normal earphone usage.
