Caution

Consult an audiologist or physician if you have excessive ear wax,

difficulty inserting the eartips,or discomfort after prolonged use.

hf2 headset + earphones exclude most external sounds. While

driving, always leave one ear open. It is unsafe to use in-ear

earphones while operating a motorized vehicle,operating

machinery,bicycling or jogging,because you may not be alerted

to potential danger.

Do not use the headset at excessively loud levels. Research

confirms that earphones that seal the ear canal allow listeners to

choose safer listening levels. Noise-induced hearing loss is a

function of exposure time, the average sound level and the peak

of very loud sounds. Sealed eartips and lower listening levels

allow for longer periods of safe listening time.

Performance

A full bass response depends on proper earphone insertion. For

best results, earphones must seal in the ear canals.

Proper Care

• Do not expose the headset to extreme temperatures.

• Avoid dropping and strong impact.

• Leave eartips on the earphones for shock protection.

• Do not pull on the cord to remove the headset from the

device or the ear.

• Clean or replace flanged eartips prior to use by others.

• Replace disposable foam eartips regularly.

• Clean or replace flanged eartips every 6-12 months

1. Remove the eartip.

2. Clean with water and mild soap.

3. Dry the eartip.

4. Replace the eartip.

Cleaning the Eartips

Insertion

Flanged eartip insertion

• To ease insertion,moisten the

flanged eartips.

• Carefully insert one earphone at a

time while pulling up and out on the

back of the ear.

• Earphones should seal comfortably

in the ear canals.

www.etymotic.com.

Foam eartip insertion

• Use a foam eartip if a good seal cannot be obtained with a

flanged eartip.

• Roll down or compress foam eartips before inserting. Hold the

eartip in place for about 5 seconds while the foam expands to

create a tight seal in the ear canal.

Removal

Remove earphones slowly with a twisting motion to gradually

break the seal. Do not pull on the cable to remove the earphones.

Filters

hf2 earphones have special filters that smooth the frequency

response and prevent earwax from entering the earphones. A

filter is located at the end of the earphone and is visible when the

eartip is removed. If a filter becomes clogged, it should be

replaced. A dirty filter will reduce earphone output. A filter

should be changed if the loudness decreases or the sound quality

declines.

Note: Filters are not reusable.
