Instruction and Maintenance

Instructions for the first generation aQustic

1. User Controls
1.1 POWER BUTTON
Power ON (when display blank): Press □ button. Display will show factory-default or user-selected Volume levels and Background Noise Settings when the AQustic Hearing Aid is ON.
Power OFF (when displaying information). Press and hold □ button for 5 seconds until the display disappears

1.2 BACKGROUND NOISE-LEVEL SETTING
The user is able to enable and disable the background noise eliminator feature by a press of a button.
Press the □ button to change background noise setting to one of the following two settings.

1.2.1 FOR QUIET SURROUNDINGS
Used while reading and resting. The aQustic Hearing Aid will automatically eliminate background noise up to ~45dB and the earphone will be very quiet.
However, when a doorbell or telephone rings, the aQustic Hearing Aid will be activated and amplify the sound, allowing the user to use everyday indicators.
When the Noise Level is at Three Bars, the aQustic Hearing Aid will filter out, not amplify, constant high decibel sounds. This setting is preferred when the noise level is very high and the User prefers a relatively quiet environment.
1.2.2 FOR VERY NOISY SURROUNDINGS
The “No Bar” level may also be preferred when the User needs to hear sound details, for instance, watching TV, listening to music, engaging in a conversation, taking a walk, or being in a crowd.
1.3 VOLUME CONTROL
Pressing the ▲ button on the left increases the volume level of the aQustic Hearing Aid; pressing the ▼ button on the right decreases the volume. Each press changes the Digital Volume Display, UP or DOWN by one level, each indicating a change of 1 dB in volume.
NOTE: The maximum volume level of the aQustic Hearing Aid is reached when 31 is displayed.
This number represents the highest dB level the human ear can safely tolerate. Any higher volume of sound could cause discomfort or even hearing impairment.
2. USING THE aQustic HEARING AID
2.1 FIRST TIME USE INSTRUCTIONS
1.Power on the aQustic Hearing Aid as described in Section 3.1
2.Ensure the volume is set to a low value.
3.Locate the earphone jack found at the bottom of the aQustic Hearing Aid.
4.Insert the earphone connector into the earphone plug.
5.Slowly bring the earphone to your ear. If the earphone is too loud, reduce the volume to a lower level.
6.Insert the ear foam into the ear canal. DO NOT force the device into your ear. The foam should sit comfortably on the outer side of the ear canal.
7.Adjust the Volume to a comfortable level.
2.2 SPECIAL DYNABLOKR© FEATURES OF YOUR aQustic HEARING AID
2.2.1 AUTOMATIC FEEDBACK NOISE ELIMINATION
Elimination of feedback noise is achieved automatically.
Feedback noises can occur occasion when the user is not wearing the aQustic Hearing Aid or has not placed it properly. When improper use occurs, even harmlessly, the amplifier in the aQustic Hearing Aid will produce a series of low “beep” sounds. When the user then adjusts the earphone or some aQustic Hearing Aid setting, the “beep” sounds stop and the device performs normally.
2.2.2 AUTOMATIC VOLUME CONTROL
The aQustic Hearing Aid can automatically reduce the volume of very loud, continuing sounds in the surroundings. It can even block some extremely loud, brief sounds, by turning them into a soundless moment. When the volume of surrounding sounds happens to be extremely high, e.g. the user or someone nearby talks loudly; the aQustic Hearing Aid automatically reduces the volume to a comfortable level and keeps it at that level.
When some irritating loud noises occur near the User, e.g., the sound of metal objects clanging, porcelain or glassware breaking, or even very loud speech, the aQustic Hearing Aid will automatically transform such harsh noises into very quiet moments, thus avoiding such extremely loud sounds from causing discomfort or harm.
2.3 OPERATING THE TELEPHONE WITH THE aQustic HEARING AID
When answering a telephone call using a conventional telephone or a cell phone, the user places the aQustic Hearing Aid microphone near, but not touching, the receiver of the phone. The aQustic Hearing Aid microphone is in the thicker part of the earphone cord located 6 cm (about 3 inches) from the earphone.
If the microphone gets into direct contact with the phone receiver the user might hear a buzzing noise. If available, the most convenient way to use the aQustic Hearing Aid with a telephone is to set the telephone phone to operate in “hands-free” or Speaker  mode.
2.4 RESETTING THE aQustic HEARING AID
On rare occasions, due to electro-magnetic interference from nearby equipment or other electronic shocks, the aQustic Hearing Aid’s microprocessor may occasionally freeze. When that happens, control buttons may stop working, no sound from the earphone, etc. Fortunately, the user can usually restore full function by resetting the device. This is done by inserting the stem of the Reset Pin into the Reset Access hole.

(If the Reset Pin is not available, a small paper clip or similar item may be used.)
Insert the pin no more than 2 mm (1/8 inch) pressing very gently! When you can feel a little click; take out the pin. The aQustic Hearing Aid restarts with factory settings.
Avoid damage to the aQustic Hearing Aid during Reset:
•Do not use too large or too small a pin, if using a substitute pin instead of the correct size Reset Pin provided.
•Do not press the Reset pin into the access hole more than 2 mm.
•Do not use any considerable force.
•If you make more than a few attempts to do a Reset, properly applying the directions above, but the aQustic Hearing Aid still does not work, then contact the sales representative for servicing.
