While purchasing a hearing system is a major step, it is only one
step in a process towards more comfortable hearing. Successfully
adapting to the amplification your hearing system provides takes
time and consistent use.
You will enjoy more benefits from your Hearing Direct HD85 hearing
system by taking the following actions:
Wear the system regularly in order to get comfortable with
using it.
Begin by wearing your system for short periods of time in quiet
As you get more comfortable with the system, increase the
wearing time and wear your hearing system in multiple types
of listening environments.
It may take as long as several months for your brain to get used to
all the “new” sounds around you. Following these suggestions will
give your brain time to learn how to interpret amplification and
increase the benefits you get from using a Hearing Direct HD85
hearing system.

Close proximity to a telephone can sometimes cause hearing
instruments to make a squealing sound, also known as feedback.
To reduce the potential for this problem, your system is equipped
with feedback suppression, which greatly reduces the chance of
Further measures to avoid feedback include positioning the phone
close to the hearing instrument, but not directly on the instrument.
If there is feedback, it may take a few seconds for the instrument’s
signal processing to adapt. This technique may require practice.
Removing the
Open the battery compartment completely with your fingernail
under the nail grip and pull gently to open it completely. Remove
the used battery from the battery compartment.
Tip: Hold the instrument over a table or a soft surface in case the
battery falls out.
Your HD85 takes a size 10A battery.
Inserting the
Remove the film from a new battery and place the new battery into
the battery compartment, matching the plus (+) sign on flat side of
the battery to the plus sign in the battery compartment. A
magnifying glass and good lighting may be helpful in seeing these
small markings. Close the battery compartment tightly but do not
use force - it should close very easily. Your hearing system should
now be on.
Tip: Removing the battery when the instrument is not being worn
will help prevent corrosion of the battery contacts. Corrosion can
decrease efficiency, causing excessive battery consumption.
Battery safety
Dispose of used batteries properly.
Keep batteries out of reach of children or people with
diminished mental capacity.
Keep batteries away from pets.
Do not place batteries in your mouth. If a battery has been
swallowed, consult a GP immediately.
To prevent batteries from leaking or exploding:
Do not expose batteries to temperature extremes.
Do not dispose of batteries in fire.
Do not attempt to recharge batteries which are not specifically
designated rechargeable, or reverse a battery’s polarity.
Maintenance and
Earwax (cerumen) can accumulate in and on the sound outlet
during use. Therefore, clean the sound outlet regularly. Failure to do
so can lead to an accumulation of earwax, impairing sound quality.
Keep your hearing instrument clean and dry. Wipe the case with a
soft cloth or tissue after use to remove grease or moisture. You
should avoid exposing your instrument directly to moisture such as
rain or water from the shower. If your instrument does get wet or if
it has been exposed to high humidity or perspiration, it should be
left to dry out overnight with the battery out and the battery
compartment open.
Alternatively, you could store the instrument in a dry aid kit
available from www.hearingdirect.com
When you are not using your instrument, keep or transport it in the
box supplied. Leave the battery door open. Keep your instrument
in a dry place, not in a bathroom or other humid place.
Maintenance and
Cleaning the sound outlet
When the sound outlet/wax guard becomes blocked with wax, use a
dry cloth or the brush provided to clean the wax away.
General advice
Things that can damage your HD85
Keep in mind that some of your day-to-day routines require that you
remove your hearing system.
Avoid getting moisture in the hearing system. It should not be worn
in the shower, bath, or sauna. Do not submerge the instrument in
water or other liquids. If perspiration or humidity is an issue, you
may find it beneficial to use a drying kit specially designed for
hearing systems.
Temperature extremes
Do not expose your hearing system to extremes of heat.
Some typical situations to avoid:
Do not wear your hearing system when using a hair dryer.
Do not leave your hearing system in your car or in direct
Do not attempt to dry your hearing system in any device other
than an approved drying kit.
General advice
Rough treatment
Protect your hearing system from rough treatment by storing it in
the provided carrying case when it is not in use.

Non-Approved Cleaning Solutions - If you use cleaning
products, only use those recommended by your hearing
healthcare professional, as housing can be damaged by certain
cleaning agents such as mineral acids, hydrocarbons (benzol),
esters, alcohols and ketones.
Debris from Daily Hygiene Routines - It is suggested you not
wear your hearing system while applying the following:
hairspray, cosmetics, colognes, perfumes,
