　　Instruction For Use:

　　When worn properly and given adequate care, this sound muffler provides excellent protection by filtering out high frequency noise caused by machinery, motors, saws, and gunfire.

　　1.Extent headband to maximum “ open” position

　　and place the cups over the ears with the

　　headband passing over the head.

　　2.Settle the headband in position on the head

　　while adjusting the height of the ear cups up or

　　down until they feel comfortable and the

　　headband rests on the top of the head to

　　support the muffs.

　　3.Make sure that the headband is evenly

　　adjusted,left to right. The ear cushion should

　　be a snug fit against the head.

　　4.Make sure to get as little hair as possible

　　between he ear cushions and your head.

　　Muffs should be cleaned regularly with soap and

　　water

　　Example:

　　1.The environmental noise level as measured at the

　　ear is 93 dBA.

　　2.The NRR is 27 decibels (dB)

　　3.The level of noise entering the ear is

　　approximately equal to 64.5dBA.

　　CAUTION

　　For noise environment dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protection can be recommended for protection against the harmful effects of impulse noise, the Noise reduction Rating 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

　　INFORMATION REQUIRED BY EPA:

　　The level of noise entering a person’s ear, when Hearing Protector is worn as directed, is closed approximated by the difference between the A-weighted environmental noise and the NRR.

　　Electronic Hearing protection Instructions

　　Thank you for your purchase of the Oulijia ElectronicEF300 Stereo Hearing Protection. These specially designed over-ear hearing protectors not onlyprotect your hearing from loud sources such as gunfire, but alsoallow youtohear normal conversation, range commands, even the sound of game in the woods. The EF300 features an electronic amplification mechanism that clarifies low pitch sounds, but “shuts down” within milliseconds when sounds above 85 dB occur.

　　Instructions for Operation

　　1. Turn the switch to the ON position; the

　　LED will indicate that the circuitry is on.

　　2. Place the EF300 on your head with the

　　control mechanism on the right ear.

　　3. Adjust the volume until hearing is at a

　　normal or comfortable level to meet your

　　needs.

　　4. Turn the switch OFF when not in use; the

　　LED will go out, indicating that the

　　circuitry is off.

　　Instructions For Battery Installation or Replacement

　　1. Turn the control switch to the OFF

　　position.

　　2. Use a coin in the provided slot at the

　　bottom of the cup to pry the ear cushion

　　assembly away from the cup that contains

　　the control mechanism.

　　3. Remove the outer foam baffle. This will

　　reveal the batteries (2). Do not disturb the

　　white inner baffle.

　　4. Remove the discharged batteries.

　　5. Insert new batteries, making sure that they

　　are installed with negative (flat) end against

　　the coil spring.

　　6. Replace the outer foam baffle.

　　7. Install the ear cushion assembly by

　　engaging the top edge first and pressing in

　　at the bottom until the assembly snaps into

　　place.
