07 | PROPER SIZE AND INSERTING INTO EAR
To find the proper size, make sure that both earphones are turned off: On/Off switch (4) down = Off
(please also refer to chapter 08).
Now select the best size (S, M or L) of the silicone ear cups (2) and foam ear pads (1) and attach them
to the two earphones.
CAUTION Only a proper combination of silicone ear cups and foam ear pads ensure firm hold and
secure hearing protection.
To insert into the ear, roll and compress the foam ear pad (1) bet-
ween your fingers. Place the earphone into your ear and hold in
place for about 10-15 seconds to allow the foam ear pad to expand
and to seal within your ear.
