Your hearing aids have been fine-tuned for your right and left ear. Colored markers indicate the side:
red marker = right ear
blue marker = left ear

Insert the hearing aid:

Step 1:
Lift the hearing aid and slide it over the top of your ear.

Step 2:
Hold the receiver cable at the bend closer to the ear piece.
(If the ear piece is a sleeve, take care that the bend of the sleeve is in line with the bend of the receiver cable.)

Step 3:
Carefully push the ear piece in the ear canal. 

Step 4:
Twist it slightly until it sits well.
Open and close your mouth to avoid accumulation of air in the ear canal.

Useful tips: 

• Always wear the receiver cable with an ear piece.
• Make sure that the ear piece is completely attached.
• Insert the ear piece carefully and not too deeply into the ear.
• It may be helpful to insert the right hearing aid with the right hand and left hearing aid with left hand.
• If you have problems inserting the ear piece, use the other hand to gently pull your earlobe downwards. This opens the ear canal and eases insertion of the ear piece.

Step 1:
Lift the hearing aid and slide it over the top of your ear.

Step 2:
If your hearing aid is equipped with a custom shell or a mold, remove it by pulling the small removal cord toward the back of your head.

Step 3:
For all other ear pieces: Grip the receiver in the ear canal with two fingers and pull it out carefully. Do not pull the receiver cable.

Useful tips: 

• In very rare cases the ear piece could remain in your ear when removing the hearing aid. If this happens, have the ear piece removed by a medical professional.
• Clean and dry your hearing aids after usage.
