Safety Precautions - Electro-Voice MA-1206 Instruction Manual And Users Manual

SAFETY PRECAUTIONS

1. Please read the notes proceeded by the symbol
safety information.
2. The power supply voltage of the amplifier has a sufficiently high value to involve the risk of electrical
shock; therefore, never install, connect, or disconnect the equipment with the power supply
switched on.
3. The metal parts of the equipment are earthed by means of the power cable. If the power socket
used to Supply power does not have an earth connection, call a qualified electrician who will earth
the equipment by means of the terminal.
4. Make sure that the power supply cable of the equipment cannot be trodden on or crushed by objects,
To ensure that the cable is not damaged.
5. To prevent the risk of electric shock, never open the equipment:
user can use.
6. Make sure that no objects or liquids can get into the speaker, as this could cause a short circuit.
7. Never attempt to make any repairs that are not described in this manual. Contact your authorized
service centers or highly qualified personnel when:
The equipment does not function (or functions in an abnormal way).
The power supply cable has been seriously damaged.
Objects or liquids have got into the equipment.
The equipment has been subject to heavy impact.
8. If the equipment is not to be used for long periods of time, switch it off and disconnect the power
supply cable.
9. If the equipment gives off any strange oder or smoke, switch it off immediately and disconnect the
power from the supply cable.
PRECAUTIONS
Do not obstruct the ventilation grilles of the equipment.
Avoid having the amplifier worked on overload for a long time.
Fully tighten the screw terminals for speakers in order to ensure a safe contact.
Do not force command parts (buttons, controls, etc.).
When cleaning external parts, do not use thinners, spirits, or any other volatile substances.
No naked flame sources, such as lighted candles, should be placed on the apparatus.
