Charging your hearing aids
We recommend that you fully charge your hearing aids before using them. This is just a precaution to make sure
that you don't run out of power unexpectedly. To learn how to charge your hearing aids, please consult the user
guide for your hearing aid charger.
Battery warnings
WARNING:
•Rechargeable hearing aids contain Li-Ion batteries. Exposure or ingestion can be seriously harmful.
•Never put your rechargeable hearing aid in your mouth. Keep your rechargeable hearing aid away
from pets, children and people with cognitive, intellectual or mental health challenges.
•If a Li-Ion battery or a rechargeable hearing aid is swallowed, seek immediate medical attention.
•If the outer casing of your rechargeable hearing aid is broken, the rechargeable batteries inside may
leak. In this case, do not attempt to use the hearing aid – contact your hearing care professional.
•Battery leakage can cause chemical burns. If you get exposed to battery leakage material, rinse
immediately with warm water. If you get chemical burns, redness or skin irritation from battery leakage,
seek medical attention.
•Batteries are harmful for the environment. Therefore, never try to burn them – dispose of your used
rechargeable hearing aids according to your country’s regulations or return them to your hearing care
professional.
10 Charging your hearing aids

•For safety reasons, use only the charger provided with your hearing aid.
•When traveling, consult your airline about any rules for transportation of your hearing aid and charger.
Low battery alert
When the batteries are low on power, the volume in your hearing aids will momentarily reduce and a melody will
play every 15minutes until there is no more power - then your hearing aids will turn off.

Left hearing aid (blue marking) Right hearing aid (red marking) Colour marking shown here
Model with hook shown as example. Thin-tube models are colour marked in the same way.
CAUTION: If you have two hearing aids, they may be programmed differently. Do not swap them as this
could damage your hearing.
Your hearing aids are colour-coded. Left=blue.Right=red.
If your hearing aids are not colour coded, ask your hearing care professional to add colour coding.
12 Placing your hearing aids in your ears

Inserting earmoulds into your ears
1. Hold the earmould between
your thumb and index finger and
position its sound outlet in your
ear canal.
2. Slide the earmould all the way
into your ear with a gentle,
twisting movement.
3. Turn the top part of the
earmould gently backwards and
forwards so it tucks behind the
fold of skin above your ear
canal. Move the earmould up
and down and gently press it to
place it correctly in the ear.
4. Place the hearing aid firmly
behind the ear and make sure it
sits securely. When properly
inserted, your hearing aids
should fit snugly and
comfortably.
NOTE: It may be helpful to pull your ear up and outward with your opposite hand during insertion. By
experimenting, you may discover an easier method.
CAUTION: Never attempt to modify the shape of the hearing aid, earmoulds or tubing yourself.
Placing your hearing aids in your ears 13

Inserting the dome into your ear
If your hearing aids have domes, follow these instructions:
1. Hang the hearing aid over the
top of your ear.
2. Hold the tube where it bends
and gently place/push the dome
into your ear canal.
3. Push the dome far enough into
your ear canal so that the tube
rests against your head. You
can check in a mirror.
NOTE: To avoid whistling, ensure that the tube and dome fit correctly into your ear. If you continue to
experience whistling, check the troubleshooting guide for other possible reasons and solutions.
CAUTION: Never attempt to bend or modify the shape of the tube.

reactivate when you remove them from the turned-on charger.
Your hearing aids always start in program1 at the pre-set volume.
NOTE: If the charger is disconnected during use, the hearing aids in the charger will turn off.
Explanation of indicator lights on the hearing aid:
•One 2-second green blink: The hearing aid turns on and is in operating mode.
•Three 1-second green blinks: The hearing aid turns off.
•When the hearing aid is present in the charger, green indicator lights pulsate: The hearing aid is recharging.
•When the hearing aid is present in the charger, green indicator lights are steadily on: The hearing aid is fully

18 Using your hearing aids

Smart Start
Smart Start delays the time before your hearing aid turns on after you remove the hearing aid from the charger.
With this function activated, you will hear a beep for each second of the delay period (either 5 or 10 seconds).
NOTE: If you do not want to use this function, ask your hearing care professional to deactivate it.
Adjusting the volume
Your hearing aid automatically adjusts the volume depending on your listening situation.
You can also adjust the volume by means of a ReSound remote control or the ReSound Smart 3D™ app.
When you change the volume, the hearing aid responds with a beep. When you reach the upper or lower limits,
the hearing aid responds with a low-pitched beep.
NOTE:
•If you have two hearing aids with the Synchronised Volume Control function enabled, volume control
adjustments to one hearing aid automatically repeat in the second hearing aid. When you change the
volume in one of the hearing aids, it responds with one or more beeps. A beep in the second hearing
aid follows.
Listening programs
Your hearing care professional can activate one or more listening programs in your hearing aids. These
programs can help you in specific situations. Ask your hearing care professional about which programs could be
useful for you.
