Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer.
The equipment / support / trolley assembly must be moved with extreme caution.
Sudden stops, excessive pushing force and uneven floors may cause the assembly to
overturn.
10.
There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
11.
Hearing loss
Exposure to high sound levels can cause permanent hearing loss.
The acoustic pressure level that leads to hearing loss is different from person to person and
depends on the duration of exposure. To prevent potentially dangerous exposure to high
levels of acoustic pressure, anyone who is exposed to these levels should use adequate
protection devices.
When using a transducer capable of producing high sound levels, it is necessary to wear
ear plugs or protective earphones.
See the technical specifications in the instruction manual for the maximum sound pressure
loudspeakers are capable of producing.
12.
To prevent the occurrence of noise on the cables that carry microphone signals or line
signals (for example, 0 dB), only use screened cables and avoid running them in the vicinity of:
-
Equipment that produces high-intensity electromagnetic fields
-
Mains cables
-
Loudspeaker lines.
13.
Do not point microphones at near loudspeakers (in order to avoid feedback).
14.
Place the receiver far from any heat sources and always ensure adequate air
circulation.
15.
Never force the control elements (keys, knobs, etc. ).
16.
Do not use solvents, alcohol, benzene or other volatile substances for cleaning external
parts. Clean with a dry cloth only.
NOTES ABOUT BATTERIES
1.
Use non-rechargeable AA type (1.5 V) batteries, better if alkaline and new.
2.
Do NOT use old and new batteries at the same time.
3.
Do NOT put together different models of batteries.
4.
Do NOT attempt to charge non rechargeable batteries.
5.
Verify the polarity of batteries is correct (inserted properly, following the indication on
the relevant compartment).
6.
Remove batteries when empty or in the case the device will not be used for a
long time.
7.
Do NOT short-circuit batteries (i.e. connecting the 2 opposite poles together with
metallic wires).
8.
Throw empty batteries into dedicated garbage cans, according to your country laws
about ecology and environment protection.
9.
Never dispose of batteries in the fire or immerse in water.
