dusts exist or can occur. Avoid operation in the immediate vici-
nity of
- strong electromagnetic fields (loudspeakers or magnets)
- electromagnetic fields (transformers, motors, coils, relays, etc.)
- electrostatic fields (charge/discharge)
- transmitter antennae
... because otherwise errors in measurement can result. Avoid
operation in very moist and wet surroundings.
• When safe operation is thought no longer possible, the in-
strument should be placed out of service and unintentional
operation prevented! It can be assumed that safe operation is
no longer possible, if the Sound Level Meter
- no longer functions
- shows visible damage
- has been stored for an extended period under adverse con-
ditions, or
- severe transportation stress cannot be ruled out.
• Never operate the Sound Level Meter immediately after it has
been brought from a cold into a warm room. The resulting
condensation water could damage the instrument. Allow the
instrument to reach room temperature.
• Measuring instruments do not belong in the hands of children.
• Use only a soft, damp cloth for external cleaning of the in-
strument. Under no circumstances use solvents or similar for
cleaning.
• The unit may only be operated using a 9V battery exclusively.
Never attempt to power the instrument with a different vol-
tage or with other batteries.

Empty batteries can be disposed of in specialist shops in the
collection containers provided for this purpose.
• Observe correct polarity when installing batteries!
• Do not leave batteries lying about openly because of the dan-
ger that they will be swallowed by children or pets. Seek
immediate medical help should swallowing occur!
• Leaking or damaged batteries can cause irritation when tou-
ched by the skin, therefore suitable protective gloves should
be worn.
• Take care not to short-circuit batteries. There is danger of
explosion.
• Do not attempt to recharge batteries. There is danger of
explosion.
3. Product description / Items supplied
The Sound Level Meter is intended for measuring noise levels of
all possible sound waves up to an intensity of 126dB. It is a tool
for use for example in the measurement of radiated-sound
installations, adjustment of stereo equipment levels, testing of
sound insulation or simple measurement of environmental noise,
etc.
The sound is transmitted via a sensitive microphone in the head
end of the measuring instrument in the form of an electric vol-
