Transmitter
• Protect the transmitter from moisture and sudden impacts. You could either injure yourself or others
or damage the transmitter.
• Do not blow into the microphone. In a condenser microphone this could damage the transformer.
It is preferable to carry out a speech trial.
• Clip-on microphones are often very compact. If they are accidentally swallowed there is a risk of
choking. Always keep this type of microphone away from small children.
• Always switch off the transmitter before charging or changing the battery.
• If the transmitter is fitted with a normal battery, never charge it in the charging unit. The transmitter
or the batteries could be destroyed. There is a risk of explosion.
• The normal commercial 9 V alkaline batteries can have a length tolerance of 2 - 3 mm. When
changing the battery always ensure good contact.
• From time to time the battery contacts should the moistened with spirits or alcohol and cleaned
with a soft cloth.
• If the transmitter is not being used for weeks or months, please remove the batteries. Batteries can
leak when not being used for a long time and corrode the conductor strips and components.
Repair is not then possible. In this case all warranty claims are null and void. The description “leak
proof” on batteries is no guarantee that they will not run out.
• Never take batteries apart yourself. The battery acid contained will damage skin and clothing.
• Do not throw used batteries into the domestic rubbish, but hand them in to local collection points.
• This equipment needs adequate ventilation. Do not cover ventilation grilles. If the heat it generates
cannot be dissipated, the equipment could be damaged or flammable materials in its immediate
vicinity could be ignited. Take care to ensure that the air can circulate freely through the ventilation
grilles and keep flammable materials away.
• Never place naked flames near the equipment.
• If the equipment causes a blown fuse or a short circuit, disconnect it from the mains and have it
checked and repaired.
• Do not open the equipment without authorisation. You could receive an electric shock. Leave all
service work to authorised expert personnel.
• Do not hold the mains cable with wet hands. There must be no water or dust on the contact pins.
In both cases you could receive an electric shock.
• The mains cable must be firmly connected. If it is loose there is a fire hazard.
• Always pull out the mains cable from the mains and/or from the equipment by the plug - never by
the cable. The cable could be damaged and cause an electric shock or fire.
• If the power cable is connected, avoid contact of the unit with other metallic objects.
• Do not insert objects into the ventilation grilles or other openings. You could damage the
equipment and/or injure yourself.
• Do not use the equipment if the mains plug is damaged.
• When installing the device into a 19" rack, make sure that the mains switch, mains plug and all
connection on the rear of the device are easily accessible.
• When connecting a headphone, please make sure that the volume is turned down to minimum.
Adjust the volume after putting on the headphone. Do not set the volume too high, as you could
permanently damage your hearing.
