Rion HB-54 User manual

5. When removing the battery, attach the
bottom of the brush to the side of the
battery. The magnet of the brush attracts
the battery, so you can remove it easily.
Be sure to remove the battery when the hearing aid is not to be
used more than one week.
In addition, Zinc-air battery may be discharged gradually after
removing the tab.
Battery life: Approx. 270 hours (IEC), 230 hours (ANSI)
(PR-48 or A13HP, for continuous use)
Battery life will change depending on the operat-
ing condition.
O-T-M Switch
O: Power off
Set to "O" when the hearing aid is not in use.
T: Induction coil (Telephone coil)
Set to "T" when the hearing aid is used for
telephone or loop system.
When the switch of the hearing aid is set to T, noise may be
heard in the vicinity of electromagnetic fields, such as generated
for example by electronically secured gates or similar.
M: Microphone
Set to "M" for ordinary use.
When taking off the hearing aid, set the switch to "O". If not,
whistling (acoustic feedback) may occur.
When setting the switch to "O", a short whistling sound may be
heard. This is not a problem.
Volume Control (Vol. 1 to 4)
1. Turn the volume all the way down (Vol. 1)
before putting your hearing aid in your ear.
2. Then, adjust the volume to the appropriate
level.
The best position of the control will depend
on the distance and sound level you want to hear.
Battery Placement
1. Remove the tab on the battery
(PR-48 or A13HP).
HOW TO USE YOUR FIRST HEARING AID
zAny hearing aid cannot return level of your hearing to normal or
halt further hearing deterioration, but proper use of your hearing
aid can help you hear what is going on around you and let you
get more enjoyment of life.
z
If this is your first hearing aid, you - like most new users - will
probablybesurprisedattheloudnessofthesounds,andafterusing
itforashortwhile,youmayevenfeelthatitistoonoisy.Thefollowing
three tips are important in overcoming your concerns.
1) Read this manual and become familiar with the hearing aid's
various mechanisms and how to use them correctly.
2) First, use your hearing aid in a quiet place and listen to quiet
sounds and give yourself sufficient time to get accustomed
to the sound of your hearing aid.
3) If any physical problems develop, consult your doctor.
FOR KEEPING YOUR HEARING AID LONGER
zAlways keep the hearing aid clean. Clean the hearing aid with
dry cloth periodically and also remove earwax plugged in the
earpiece or earmold using eyebrush or toothbrush.
zDo not expose the hearing aid to the heat from stoves, etc. Also,
avoid leaving it in places with high humidity.
zOperate the controls with care. Do not press hard.
zIf the hearing aid is dropped in water, wipe with dry cloth and ask
the dispenser for check.
zDo not pick the microphone with nail, pin, etc., because this may
damage the microphone.
zDo not disassemble or attempt any repairs by yourself. Ask the
dispenser for repair.

How to Open and Close the Control Cover
1. Slide the Lock Lever upward with the screw driver and open
the Control Cover as illustrated.
2. Do not lift up the Control Cover too far.
3. After trimmer adjustment, close the Cover pressing it with a
finger and slide the Lock Lever downward until it is locked.
Trimmer Adjustment
TONE H (Low Cut):
Turning this trimmer clockwise (N to H) reduces the
amount of low frequency amplification.
Maximum reduction at 500 Hz is 32 dB.
TONE L (High Cut):
Turning this trimmer counterclockwise (N to L)
reduces the amount of high frequency amplification.
Maximum reduction at 2500 Hz is 14 dB.
Output Limiting Control (OGC)
The OGC can reduce the maximum output in overall
frequencies as well as the acoustic gain.
Turning this control counterclockwise can reduce its
output and gain by up to 18 dB and 20 dB, respectively.
Cautions:
Specialcare must be taken incasethesoundpressurelevelexceeds
132 dB as this may further impair the user's residual hearing.
