2. FITTING AND ADJUSTMENT

The noise reduction may be lower when eyeglasses, goggles

or respirator straps are worn between the sealing surface of the

earmuff cushions and the sides of the wearer’s head. For best

noise reduction, select eyeglasses or goggles that have thin,

at temples or straps which will minimize interference with the

seal of the earmuff cushions. Pull long hair back to the extent

possible and remove other items that may degrade the earmuff

seal such as pencils, hats, jewelry or earbuds.

Do not bend and reshape the headband as this will cause a

loose t and allow sound leakage.

2:1 Headband model (Fig. B)

(B:1) Expand the headband

(B:2) Slide out the cups and make sure that the cable is on the

outside of the headband.

(B:3) Place headset on top of your head and adjust the height

of the cups by sliding them up or down while holding the

headband in place. Each earmuff should be positioned so it

surrounds the ear entirely.

(B:4) The headband should be positioned across the top of

your head.

2:2 Hard hat attachment model (Fig. C)

(C:1) Insert the hard hat attachment in the slot on the hard hat

and snap it into place (C:2).

(C:3) Make sure that the cable is on the outside of the

headband.

(C:4) Usage position: Press the headband wires inwards

until you hear a click on both sides. Each cushion should be

positioned so it surrounds the ear entirely. Make sure that the

cups and the headband wires do not press on the edge of the

hard hat as this can cause noise leakage.

(C:5) Stand by position: Snap earmuffs out to allow ventilation.

(C:6) Avoid placing the cups against the hard hat as it will stress

on the hard hat attachment and prevent the earmuffs from

drying. When the hard hat is not in use, place the cups in work

mode.

Note: In Canada, users of hard hats combined with earmuffs

must refer to CSA Standard Z94.1 on industrial protective

headwear.

2:3 Neckband (Fig. D)

(D:1) Place the cups in position over the ears.

(D:2) Keep the headset in position and place the head strap on

top of your head and lock it tight in position.

(D:3) The head strap should be positioned across the top of your

head.

2:4 Microphone (Fig. E)

(E:1 & E:2) To maintain optimal audio quality and noise

cancelling performance, the communications microphone

should be positioned very close to your mouth (3mm or 1/8in).

2:5 Replacing the hard hat attachment plate (Fig. F)

The P3K hard hat attachment is included and ts a wide

selection of hard hats. If the P3K attachment does not t on

your hard hat, contact 3M Technical Support or an authorized

dealer for alternative attachment plates. To remove the

attachment plate:

(F:1) Use a screwdriver to remove the screw holding the plate.

(F:2) Insert the new plate and tighten the screw.

3. USAGE/FUNCTIONS

3:1 Inserting and removing the battery

Insert the rechargeable battery in the battery compartment and

push down the clamp to lock it into place. The battery level is

indicated by a voice message in the headset upon startup. A

“low battery” message indicates only a few minutes of battery

life remains and the unit will automatically switch off. To remove

the battery, make sure the unit is powered off. Push the clamp

upwards to unlock the battery.

3:2 Recharging the battery

Make sure the unit is switched off. The battery can be charged

on the headset or it can be removed and charged separately.

are ve levels plus it can be turned off. As the squelch level

is increased, there will be greater suppression of static noise,

but consequently the range of communication will be reduced.

Conversely, a lower squelch level provides less static noise

reduction but will increase the range of communication. To

switch this function off, push the – button for two seconds. Push

the + button to switch this function back on.

3:4.6 Sub-channel (Canada only)

Sub-channels (selective squelch) use unique inaudible tones

that serve as a passkey, thus limiting what you hear to radios

with the same sub-channel setting. The advantage of sub-

channels is that they can be used to set up multiple private

groups within a single channel. However, it’s important to note

that only one person can transmit on a single channel at any

given time. Therefore, if anybody is transmitting on the channel,

all sub-channels will be blocked during that time. BCLO (Busy

Channel Lock Out) will prevent transmission on a busy channel.

Push the + or the – button to turn the sub-channel on or off.

This product supports Continuous Tone Coded Squelch System

(CTCSS) and Digital Coded System (DCS).

3:4.7 Power

The built-in two-way radio has three output power levels: High,

Medium and Low. A higher output power level increases the

range of radio communication but will consequently decrease

the battery life. Use the + or the– buttons to select the output

power level. A voice message conrms the new setting.

3:4:8 Language

Choose your prefered language by pushing + or -.

3:5 PTT (Push-To-Talk)

The PTT button is used to manually control the two-way radio

transmission. Push the PTT button when you intend to transmit.

4. MAINTENANCE

4:1 Replacing the ear cushions (Fig. G)

(G:1) Slide your ngers under the edge of the ear cushion and

pull straight out.

(G:2) Insert the new foam and ear cushion

(G:3). Fit one side of the new ear cushion into the groove of

the earcup and then press on the opposite side until it snaps

into place.

4:2 Cleaning

It is a best practice to remove the ear cushions (see 4:1) if you

have been wearing the earmuffs for a long time or if moisture

has gathered inside the cups. Clean and disinfect the cups,

headband and ear cushions regularly with soap and warm

water. Allow the headphones to dry completely before using

them again. With heavy use, it is recommended that the ear

cushions are replaced at least twice a year.

NOTE: Do not immerse the hearing protector in water.

4:3 Use and storage conditions

Use Conditions: Do not use the hearing protector at

temperatures below -4°F (-20°C) or above 122°F (50°C).

3.3 Switching the headset on and off

Push and hold the On/Off/Mode button (A:12) for two seconds

to switch the headset on or off. A voice message will conrm

that the unit has been switched on or off. The On/Off/Model

button will ash when the unit is powered on. The current

settings are saved when the headset is switched off. The

automatic power-off time of two hours (factory default) but can

be congured by a 3M Service Technician or an authorized

dealer. Automatic power-off is indicated by a voice message,

“automatic power off” followed by a series of short tones for 10

seconds, then the unit will power off. The automatic power off

can be aborted by pushing a button or by using VOX.

3:4 Menu

Briey push the On/Off/Mode button (A:12) to browse through

the following menu options:

3:4.1 Surround volume

Push the + or the – button to adjust the environmental sound

volume. There are ve volume levels, with level ve allowing

a maximum of 82 dB(A). To switch this function off, push the –

button for two seconds. Push the + button to switch the function

back on again.

3:4.2 Radio volume

Push the + or the – button to adjust the two-way radio sound

level. There are ve volume levels. To switch this function off,

push the – button for two seconds. Push the + button to switch

this function back on again.

NOTE: When the volume is switched off, no radio

communication can be heard and all the radio congurations

menus are hidden.

3:4.3 Channel

Push the + or the – button to change the radio channel.

3:4.4 VOX

VOX, or voice operated transmission, is a hands-free feature

that enables radio transmission without having to push a PTT

button. The VOX feature will open the radio channel upon

vocalization and close the radio channel when no speech is

detected (the speech microphone must be placed close to

your mouth (D:2)). There are ve VOX levels plus it can be

turned off. Push the + or the – button to adjust the VOX level.

The VOX level denes the acoustic threshold that activates

the radio transmission. Use the lower VOX levels for quieter

environments and higher VOX levels for louder environments.

To switch the VOX function off, push the – button for two

seconds or push the PTT button twice. Push the + button to

switch the VOX function back on. The radio has a BCLO (Busy

Channel Lock Out) function that prevents VOX operation if the

channel is being used for another transmission. A tone indicates

that the channel is currently being used.

3:4.5 Squelch

Squelch is a function that reduces the hiss or static noise

that may be heard during the two-way radio communication.

Push the + or the – button to adjust the squelch level. There
