On/Off switchand battery drawer

On-Off switch

Your SENSO hearing instru-ment has an On-Off switchbuilt into the battery drawer.The hearing instrument isturned ON when the batterydrawer is pushed upwards, andOFF when the battery draweris pulled downwards.

The OFF switch is clearlymarked with the letters OFFon the back of the batterydrawer.

Please remember always to switch the aid offwhen it is not in use for a lengthy period, or to re-move the battery.

4

Volume control

Your P37 hearing aid has adigital volume control, shapedlike a small lever. Push thelever upwards for more vol-ume. Push the lever downwardsfor lower volume. Use shorttouches for minor corrections ofthe volume. Faster adjust-

ments are obtained by keeping the lever pressedfor some seconds.

When you raise the volume, you will hear a beep-tone for each step the volume is raised. When themaximum adjustment level is reached, a steadytone will sound until you release the lever.

When you lower the volume, you will hear a deeperbeep-tone for each step the volume is lowered.When the minimum adjustment level is reached, asteady tone will sound until you release the lever.

5

SENSO P37 is equipped with a computer whichhas been designed to adjust its sound automati-cally in accordance with the sound environmentaround you. Several thousand times per second,SENSO analyzes the surroundings and tailors itssound accordingly. Therefore, with this digital in-strument you only need to adjust the volume to ob-tain as natural and comfortable a sound as possi-ble.

For further information, consult your HearingHealthcare Professional.

6

M-T switch

This switch has three click po-sitions:

“M” (Microphone only) for nor-mal use or normal listening.

“T” (Telecoil only) for telephoneuse and/or for induction loopuse.

7

Center position is an “MT” position whereby themicrophone and telecoil are on simultaneously.This position is useful for situations where simul-taneous microphone and telecoil reception is de-sired e.g., classrooms with inductive loops.

8

Change/insertion of battery

The battery drawer swings outon the opposite side of the On-Off switch.

Clean the new battery care-fully with a dry cloth to removeany sticky residue before in-serting.

The battery must be placedwith the + sign visible, in accor-dance with the + sign on thebattery drawer.

If the battery drawer does notclose easily, the battery is in-correctly inserted.

9

Exhausted batteries: If you hear four rapidbeep-tones while wearing your hearing aid, it is anindication that you should exchange the batteriesas soon as possible, as the batteries are nearly ex-hausted. Once the batteries are totally exhausted,the hearing aid will be totally silent.

Never let an exhausted battery remain in thehearing aid. Exhausted batteries may leak, whichcould damage your hearing aid.

10

Recommended energy source:Zinc Air battery 675

Zinc Air batteries can be stored up to two years, aslong as the sealing label is not removed. Do not re-move the label until just before inserting the bat-tery in the instrument.

Once inserted, the battery will start functioningafter a few seconds.

On occasions, a new battery may be exhaustedsooner because it was not sealed properly. If yourhearing aid does not work after you have replacedthe battery, try inserting a different new battery.

11

Left/Right identification

If you are wearing hearing aids on both ears(which is highly recommended if you have a hear-ing loss on both ears), and you want to make sureyou are placing them on the correct ear, you can ar-range with your Hearing Healthcare Professionalto have an identification mark mounted on theright hearing aid.

12

Never put batteries in your mouth for any reasonand never let a child obtain a battery or place it inhis or her mouth. In case of ingestion, contact yourphysician andThe National Battery Button IngestionHotline at: (202) 625-3333.

13

Storing the hearinginstrument

Please do not expose the hearing aid to excessiveheat, such as leaving it on a window sill, near a ra-diator, or on the dashboard of your car, as this maydamage your hearing aid.

14

In case of malfunction

Should your hearing aid be completely or periodi-cally dead, try the following before consulting yourHearing Healthcare Professional:

• Make sure the hearing aid is switched on tothe “M” position.

• Check that the earmold is not blocked bywax. Remove the earmold from the tubingand try to blow air through the earmold witha small blower.

• Disconnect the tubing from the hook of thehearing aid and check if there is moisture inthe tubing.

• Change the battery and make sure the newbattery is correctly inserted.

• See the Troubleshooting guide p. 22-23.

Never try to open or repairthe hearing aid yourself

as it may void the warranty.

15

Audio input

SENSO can be furnished withan audio shoe. This allows di-rect connection to CROS sys-tems as well as assistive listen-ing devices such as FM equip-ment, hand-held microphones,TVs, and cassette players.

SENSO audio shoes can be distinguished fromother audio shoes in that they have the same non-gloss surface as the SENSO aid.

Connecting the audio shoeBefore connecting, the little cover on the side ofthe hearing aid must be replaced with the coverwhich has one hole.

A Europlug is used for connection.Insert the plug into the socket onthe base of the audio shoe. Pleasenote that the plug will only con-nect one way, as one of the threepins is thicker than the other two.

Make sure that the MT switch isset on the M position.

16

Slide the audio shoeonto the hearing aid,as shown. Press theshoe gently onto theaid until you feel aclick.

A switch on the audio shoe givesyou the choice of listening to audioinput only (MIC OFF) or to audioinput plus hearing aid microphone(MIC ON).

Remove the audio shoe by gentlypulling it away from the hearingaid, as shown.

17

CROS with anaudio shoeand a CROS dummyThe audio shoe can alsobe used together with Bi-CROS. For this, a CROSdummy and a cord with aEuroplug at both endsare used.

Attention! If the hearing aid isconnected to equipment whichhas an electrical plug, this equip-ment must meet the safety re-quirements stated in the interna-tional standard IEC 65.

Do not connect the hearing aid to plugs that arelabeled with one or more of the following symbols:

Switch your hearing aid off when it is not in use.Should you not use it for a day or more, take outthe battery to avoid battery leakage.

Always insert the battery with the plus (+) sidefacing you in accordance with the plus (+) sign onthe battery drawer. If you feel the battery needs tobe forced into the compartment, then check to seeif it’s upside down.

19

The earmold

Make sure your earmold is clean and free of ear-wax and moisture. If it is plugged, clear the open-ing with a wax removing tool, a toothpick or pipecleaner.

If this is not sufficient, disconnect the plastic tubefrom the hook of the hearing aid and wash themold in lukewarm water with a mild dishwashingsoap.

Rinse in cold water and allow the mold to dry over-night. If there is still moisture in the mold or tube,use a small air blower to blow it dry.

If your earmold tubing becomes stiff, yellow orcracked, contact your Hearing Healthcare Profes-sional for a replacement.
