channels will be busy during that time. If the sub channel
feature is switched off, all communication on a channel will
be heard. Press the (+) button (A:10) or (–) button (A:11) to

Continuous Tone Coded Squelch System (CTCSS) and
Digital Coded Squelch (DCS) for a total of 38 frequencies/
codes (see table above for sub channel number and the
associated tone/code). To switch this function off press the

channel and then speak in to the microphone.
NOTE: When pushing the PTT button, the headset will
always transmit a signal regardless of the BCLO setting.

To restore the headset to factory default settings the unit
must first be switched off. Then press and hold the (+)
(A:10) and (–) (A:11) buttons at the same time while also
pressing the (A:9) On/Off/Mode button. This is confirmed
by the voice message "restore factory defaults".
4. CLEANING AND MAINTENANCE
Use a cloth wetted with soap and warm water to clean the
outer shells, headband and ear cushions.
NOTE: Do NOT immerse the hearing protector in water.
If the hearing protector gets wet from rain or sweat, turn
the earmuffs outwards, remove the ear cushions and foam
liners, and allow to dry before reassembly. The ear
cushions and foam liners may deteriorate with use and
should be examined at regular intervals for cracking or
other damage. When used regularly, 3M recommends
replacing the foam liners and ear cushions at least twice
a year to maintain consistent attenuation, hygiene, and
comfort. If an ear cushion is damaged, it should be
replaced. See Spare Parts Section below.

REPLACING THE HELMET ATTACHMENT PLATE
For proper fitting on different industrial safety helmets, the
helmet attachment plate may need to be replaced. Find the
recommended attachment in Table C. The headset comes
assembled with P3E helmet attachment. Plates for P3K

while other plates can be obtained from your dealer. A
screwdriver is needed to replace the helmet attachment
plate.
(F:1) Loosen the screw holding the plate and remove the
