Other disturbances
All electronic equipment and especially sound amplifiers such as radio/TV
sets, tape recorders, hearing aids etc. may be affected by radio waves and
magnetic fields.
E.g. Hearit
may be disturbed by mobile phones (type GSM and others) used
within 2-3 meters distance from the amplifier. The disturbance appears as a
tone or a buzzing sound. It is not harmful but may lead to a deteriorated sound
recording. To achieve the best function of the Hearit it should thus not be used
in close proximity of a digital mobile phone.
If you still have trouble after trying the ideas above please contact your local
supplier (see information on back cover).
