one weight to a different tone than the second one. The tone produced
is designated by the stamped letter, which is found directly below the
weight.
The tuning fork is to be struck preferably with the heel of the hand or
with a piece of wood or plastic, but never with an object that is too
hard (such as metal, steel or stone). The tuning fork should be struck
in a brief and spring-like manner, meaning the tuning fork is only
touched very briefly. Striking the tuning fork in this brief manner en-
sures the longest possible duration of vibration.
During the examination (sensitivity test etc.) the tuning fork is struck
and then the base of the black plastic foot on the tuning fork is placed
on the part of the patient's body that is to be examined.
Purpose: During hearing, airborne sound normally travels through
the outer ear channel to the eardrum. The signal is transferred by the
ossicle of the middle ear to the inner ear and is there taken in by the
receptor cells (aerotympanal conduction). Sound oscillations can also
be transferred through the bones, by-passing the middle ear, directly
to the inner ear (bone conduction). The transfer of sound oscillations
through air channels or bone channels depends on the frequency and
differs between aerotympanal conduction and bone conduction.
Unsuited use/contraindication of the product: Any use other
than that described here is not in accordance with the intended use of
the unit. The manufacturer is not liable for any resulting damages. The
user alone bears the risk.
Further information, maintenance, storage: When used and
stored properly, this product will serve you many years.
Guarantee: When used properly and in accordance with the User's
Manual we guarantee this product for two years from the date of pur-
chase. Should you need further information or should your instrument
require repair, please contact your dealer.
Warning: Please keep in mind that even minor damage to the
tuning fork can influence the oscillation frequency. If the tuning fork
has weights that are securely screwed on to the tines, these may not
be unscrewed. The frequency will be changed if the weights are
moved and the exact positioning of the weights can only be carried
out by the manufacturer.
Limitation of reuse preparation: Frequent preparation has only a
minimal effect on the instrument. The end of the product's life is nor-
mally due to wear and tear and damage by use. It is recommended
that these instruments be re-prepared as soon as possible after their
use.
Instructions
Storage and transport: Rydel Seiffer tuning fork: adjusting the
tuning fork after transport: During transport it is possible for the
dampers to become loose and move. Before using the tuning fork
ensure that both dampers are fastened on the tuning fork such that
the markings on the back side of the tuning fork line up with the
lower edge of the damper (see picture). Only then can we guarantee
you proper functionality (frequency) of the tuning fork.

Cleaning preparation: No special requirements.
Manual cleaning: After use, the tuning forks may not be cleaned in
a steriliser. To clean the tuning fork and the foot, gently wipe both with
a dry or slightly greased cloth.
Automatic cleaning: Please ensure that the cleaning system is suit-
able for medical instruments. Only cleaning agents suitable for metals
are to be used. The concentrations and reaction times given by the
manufacturer of the cleaning agents are to be followed.
Disinfection: Parts that come into contact with the patient are to be
disinfected after each use. Alcohol-based surface disinfecting agents
are to be used. Please heed hereby the instructions and reaction times
given by the manufacturer.
Maintenance: Damaged parts must be removed and/or replaced.
Check and performance test: Check moving parts such as the
dampers for smooth operation. Visually inspect instrument for dam-
age and wear. Before use, ensure that all screws are tightened.
Packaging: packaged individually: a standard polyethylene bag can
be used. The size of the bag must correspond to the size of the instru-
ment so that it closes properly without straining the bag closure.
