Operating instructions
Checking the mains voltage:
Before turning on the unit, check if the voltage selector (21) at the rear panel of the
unit is set to the proper line voltage. The unit is suitable for connection to a. c. mains
only. Setting to another voltage is accomplished by means of a screw driver or a
suitable coin which should be turned until the mark points to the respective mains
voltage.
The unit is set for 220 volts in the factory. The mains fuse (30) may be replaced by
turning out the cap. Repeated blowing of properly sized and rated fuses indicates
a defect in the unit. Underfusing may cause blowing of the fuses even though the
unit is not defective. Mended fuses or overfusing may cause severe damage to the
unit which is not covered by warranty. The electrical value is impressed on one of
the two fuse caps at the side.
Fuses:
The size of the mains fuse is:
110 to 130 volts = 800 mA, slow
220 to 240 volts = 400 mA, slow
motor fuse:
1.6 amps. slow
appliance fuse: 400 mA slow
Dimensions of all fuses = 5 X 20 mm
Attention! Spare fuses are in a plastic bag at the rear wall of the unit (22),
Connections to mains supply:
The earting-contact-type line cord supplied with the ,ECHOCORD-SUPER 76" should
be plugged into the mains supply socket (29). The specified protection against electric
shock hazard as well as the best possible freedom from humming is secured only if
this line cord is plugged into a properly installed earthing-contact-type socket.
Depending on the local mains conditions, it may become necessary to change the
polarity of the power plug in order to secure maximum freedom from humming.
In order to eliminate so-called hum pickups, care should be taken that the, ECHO-
CORD-SUPER 76" and the amplifier used are plugged into two sockets not placed
too far from each other. The use of multiple sockets is an advantage in this respect.
