Safety Precautions

Important Information on Safe and Efficient Operation.

Read this Information Before Using your Headset.

- Listening to music or any other sound at a high

volume over time can cause permanent damage to

your hearing. Noise-induced hearing loss can occur

even when you are enjoying music on a personal

listening device. The user is responsible for proper

selection, use, care and maintenance of this device.

Improper selection use or maintenance may lead to

serious hearing loss.

- The output of the level dependent circuit of this

headset may exceed the external sound level.

- Improper fit of this device will reduce its

effectiveness in lessening noise. Although hearing

protectors can be recommended for protection

against the harmful effects of impulse noise, the

Noise Reduction Rating (NRR) is based on the

attenuation of continuous noise and may not be an

accurate indicator of the protection attainable

against impulse noise such as gunfire. Constant or

repetitive exposure to impulse noise may lead to

serious injury, including temporary or permanent

deafness.

Getting Started

Your Motorola MHP61 provides all day comfort and

protection against moderate to loud sounds generated

by machines, gunfire and other noise sources. Proper

use and care of the MHP61 is essential for your hearing

safety and comfort. Please read and comply with the

following instructions:

Fitting the headset

Adjust the height adjustment sliders downward from the

top to an appropriate position based on your head size.

Move the cups up and down until the cups are secured

over the ear. For best results, remove all hair from under

the cushion. Noise reduction will be adversely affected

by anything that impairs the seal of the earmuff cushions

against the head such as glasses or a hat. Height

Adjustment Sliders should be evenly extended from the

headband.

Placing the ear cups over each ear

The input jacks can face either forward or backward,

depending on how you intend to drape the cable

assembly when connecting to an audio or 2-way radio

device..

Removing and replacing damaged or worn-out ear seals

1. Hold the cup in one hand and place the fingers of the

other hand underneath the hard plastic ear seal

flange.

2. The ear seal and flange will snap off of the cup with

moderate force.

3. Put the new ear seal over the cup and snap into

place.

Removing and replacing worn-out headbands

1. Hold one ear cup firmly in place with one hand.

2. Use your other hand to slide each pivot pin of the

yoke out of the cup's rubber socket. A slight rotation

of the cup will help release the pin from the rubber

socket.

3. Repeat 1 and 2 above to remove the other cup.

4. Hold one ear cup firmly in place with one hand.

5. Rotate and press the ends of the yoke pins of the new

headband into the 2 rubber sockets located on the

ear cup.

Connecting your audio player to your headset

1. Locate the cable assembly with the 3.5 mm plug at

the end.

2. With your headset off, plug the white and red 2.5 mm

connectors into the jacks on each cup. The headset

has no front or back. You should ensure that the left

and right connectors are plugged into the accessory

jack that matches your preferred way of wearing the

headset.

3. With your player off, plug the headset's single

connector into the player's accessory jack.

4. Turn the music player on and adjust volume to a

comfortable listening level.

Connecting your Motorola Talkabout® 2-Way radio to

your headset

1. Locate the cable assembly with PTT microphone and

all black 2.5 mm connectors.

2. With your headset off, plug the black/red connectors

into the jacks on each cup. The headset has no front

or back. The 2-Way radio is monophonic, and the left

and right connectors can be plugged into either cup.

3. With your 2-way radio off, plug the 2.5 mm connector

into the radio's accessory jack.

4. Turn the radio on and adjust the volume to a

comfortable listening level.

5. Hold the PTT microphone 2.5 cm from the mouth for

best audio clarity.

6. To transmit, press the PTT (Push-To-Talk) button. To

receive, release the button.

IMPORTANT USER INSTRUCTIONS

1. The earmuffs should be regularly inspected for

serviceability.

2. If you encounter excessive crackling or distortion in

the speakers, contact the manufacturer calling the

number in the warranty section of this user guide.

3. Inspect the ear cushions for cracks or hard spots or

separation from the cups. Replace damaged or

worn-out ear seals.

4. After extended use, clean/disinfect ear seals with a

soft cloth and warm soapy water. DO NOT SUBMERSE

EARMUFFS IN WATER! Store in a cool, dry place. The

ambient temperature for storage should not exceed 55

degrees C (130 degrees F).

5. The earmuff is equipped with an electrical audio input

jack. The user should check for proper operation

before use.

6. Two separate cord assembly cables are included. One

cable has a 2.5 mm connector and an in-line

microphone for use with your Motorola Talkabout

FRS/GMRS two-way radio. The second cable has

3.5 mm connector for use with other input devices.

Source: CSA Standard Z94.2-02

The MHP61 is rated CSA Class B.

The NRR calculated from these laboratory-based

attenuation data is 21. Improper fit of this device will

reduce its effectiveness in attenuating noise. Consult

instructions for use for proper fit.

The level of noise entering a person's ears when a

hearing protector is worn as directed is closely

approximated by the difference between the

A-weighted environmental noise level and the NRR.

EXAMPLE:

1. The environmental noise level as measured at the

ear is 92 dBA.

2. The NRR is 25 decibels. (dB)

3. The level of noise entering the ear is approximately

equal to 67 dBA.

CAUTION: For noise environments dominated by

frequencies below 500 Hz, the C-weighted

environmental noise level should be used. Earmuffs

must be worn at all times in noisy surroundings for

proper protection. Although hearing protectors can be

recommended for protection against the harmful

effects of impulsive noise, the noise reduction rating

(NRR) is based on the attenuation of continuous noise

and may not be an accurate indicator of the protection

attainable against impulsive noise such as gunfire.

The EPA has selected the NRR as the measure of a

hearing protector's noise reducing capabilities. Giant

International and Motorola make no warranties as to

the suitability of the NRR as a measure of actual

workplace protection since such protection is highly

dependent on user training, motivation, and utilization.

A better estimate of workplace protection can be

obtained by derating the labeled NRR of this, or any

other hearing protector, by 50%.
