8. My hearing aid has an “auto-switch” t-coil; will it work with a neckloop?

It will not unless you can manually turn on the t-coil. Auto-switch t-coils require a strong magnetic field to

turn on the t-coil. Older corded phones had powerful magnets in the speakers and they worked fine with

the auto-switch t-coils. Newer corded phones, cell phones and cordless phones use speakers that have

a small magnet and these do not turn on most of the auto-switch t-coils. Many hearing aid manufacturers

ship a magnet with the hearing aid to help the user turn on their t-coil. Neckloops generate

electromagnetic fields which are not magnetically strong enough to turn on the auto-switch t-coils. You

need to discuss your options with your hearing aid provider. We suggest that to get the maximum benefit

that you demand the ability to control when you can turn the t-coil on and off. Auto-switch t-coils do not

work effectively with neckloops or cell phones.

9. Sometimes the sound thru my neckloop is distorted, why? Can I make it clearer?

Yes, you can easily correct that situation. All sound can become distorted if it is amplified too much. The

CLA7 has a 30dB amplification capability and many devices do send amplified sound thru the connectors

used with the CLA7. If the sound is distorted, it means that you have too much amplification and you

need to adjust either the volume control on the CLA7 or the volume control on the telephone or sound

device you are using. If you have hearing aids with a volume control you may have to adjust the hearing

aid volume as well. Fixing the distortion is easy. Just adjust the volume controls to a lower level.

However, if the sound source is sending distorted or garbled sound, there is nothing the neckloop or any

other device can do to fix that – it’s the “garbage in; garbage out” rule. If you are using a cordless phone

or a cellular phone you may be at the edge of the range of the phone and the signal gets fuzzy.

Telephones are not high fidelity devices and conversations are not always clear. If nothing else works, try

hanging up and making a new call; the new call will most likely go thru a different set of connections and

may clear up.

10. How do I know when the batteries in the CLA7 are low?

The green LED light in the top of the CLA7 that tells you the neck loop is on will turn amber or red telling

you it is time to change batteries.

11. Can I use rechargeable batteries?

Yes, you can. Rechargeable AAA batteries are fine for use with the CLA7. There is no recharging

capability built into the CLA7 so you will have to use an external charger. The beauty of the CLA7 is that

if you are using rechargeable batteries and your batteries run low while away from your home or office,

you can go to virtually any corner store and purchase AAA batteries that will work fine. Installing new

batteries is really easy.

12. How long will the AAA batteries last?

That depends on how much the neckloop is used, how much amplification is used and the type of

batteries used. These are variables that affect how much power is used or is available. In average use

with average batteries, we find that the CLA7 will operate for approximately 100 hours.

13. I am in my car using the CLA7 with my cell phone and I get a buzzing sound, what is it?

3 of 4

Unfortunately, the t-coil in your hearing aid or cochlear implant and the neckloop itself will pick up

electromagnetic interference (EMI) generated by your car. The amount of EMI generated varies from car

to car based on amount of electronics in the car and if the car manufacturer tried to shield the EMI

generators. Airplanes can also generate a lot of EMI. If the t-coil in the hearing aid is not shielded and

the EMI is very strong, the amplification in the CLA7 may not be able to override the interference. In most

cases communication is possible with the buzzing a tolerable nuisance. EMI can also be generated by

computers and other electrical devices. If you are using your neck loop in proximity of electrical devices

you may experience a buzzing. To correct move away from the device. If you are using a digital cell

phone or a digital cordless phone they may also generate EMI that is picked up by the t-coil. Keep these

devices away from your hearing aids.
