• Remove all batteries from the 620 series if you will not use the instrument
for a long time.
• Always follow local regulations to dispose of used batteries.
CAUTION
Care should be taken that the operator does not unduly affect the sound field.
Ideally the instrument should be mounted on a sturdy tripod with the microphone
perpendicular to the source of the sound to be measured and the operator should
be as far behind the instrument as possible. If the instrument is to be hand-held,
then the arm of the operator should be stretched out as far as possible to
minimise reflections from the operator’s body.
WEEE Notice
At the end of the instrument’s life please do not throw away with the
unsorted municipal waste. Please recycle with a registered WEEE
handler.
