NOTE: To effectively use VOX, the speech microphone (A:8)
must be very close to your mouth, less than 3 mm (1/8 inch).
You will hear your voice in the headset when the radio is
transmitting.
9.4. SQUELCH
(Figure A:10 - A:11)
Hiss reduction.
The "squelch" feature will reduce the distracting radio hiss or
static noise. You can choose between five squelch levels by
pressing the (+) button (A:10) or (–) button (A:11). A higher
squelch level will further reduce the noise, but will also
reduce your range of reception. To switch this function off,
press the (–) button for two seconds. Press the (+) button to
switch this function back on.

The sub channel feature can be used to set up multiple
private groups within a single channel. When the sub channel
feature is active, an inaudible code will be transmitted with
the speech and only the receivers with the same sub channel
setting will hear the transmission.
However, if anybody is transmitting on the channel, all sub
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
select the sub channel. The LiteCom headset supports
Continuous Tone Coded Squelch System (CTCSS) for a total
of 38 frequencies/codes (see table K:B for sub channel
number and the associated tone/code). To switch this
function off press the (–) button when sub channel 1 is
selected, or press the (+) button when channel 38 is selected.
Press the (+) button to switch this function back on.
9.6. RESET TO FACTORY DEFAULTS
(Figure A:9 - A:11)
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".

Description
10. PRODUCT LIFETIME
It is recommended that you replace your product within
5 years from date of manufacture. The lifetime of the product
will be highly dependent on the environment in which the
product is stored, used, serviced, and maintained. The user
must regularly inspect the product to determine when it has
reached its end of life. Examples that the product may have
reached its end of life are:
• Visible defects such as cracks, deformations, loose or
missing parts.
• Experience of a deterioration in the hearing protector's
attenuation performance, strange noise or abnormal high
sound volumes from the product's electronic sound
reproduction.
NOTE: Product lifetime does not include batteries.
11. CLEANING AND MAINTENANCE
Carry out a visual battery condition check. Replace if battery
leakage or defects are detected.
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 and accessories section below.
11.1. REMOVING/REPLACING EAR CUSHIONS
(Figure D:1 - D:3)
D:1 To remove the ear cushion, slide your fingers under the
inside edge of the ear cushion and firmly pull straight out.
D:2 Remove existing liner(s) and insert new foam liner(s).
D:3 Fit one side of the ear cushion into the groove of the
earcup and then press on the opposite side until the ear
cushion snaps in place.
11.2. REPLACING THE HELMET ATTACHMENT
PLATE
(Figure E:1 - E:2 and table H)
For proper fitting on different industrial safety helmets, the
helmet attachment plate may need to be replaced. Find the
recommended attachment in table H. The headset comes
assembled with P3E helmet attachment. A screwdriver is
needed to replace the helmet attachment plate.
(E:1) Loosen the screw holding the plate and remove the
plate.
(E:2) Attach the appropriate plate while ensuring the left (L)
and right (R) designated plates are on the appropriate
earmuff, if applicable, and then tighten the screw.
