Mains fuse:
T 3,15A for 220Vac and T 6A for 110Vac
The unit is only safety approved using the following fuses,
as appropriate:
Wickman 181 1630 000 (1000pcs) or 002 (10 pcs) (110V) or
Wickman 181 1315 000 (1000pcs) or 002 (10 pcs) (230V)
Programming the hand switch
The remote hand switch is pre-programmed
for the supplied Nor280. Several hand
switches can be programmed for one or
more amplifiers or vice versa. The procedure
is as follow:
• Switch on the amplifier.
• Push a small rod (paperclip) into the
tiny hole located to the right above the
mains switch. This activates a push
button
• Press and release the button located
on the remote hand switch
• Repeat the press and release
• Wait 20 seconds
• The hand switch is now programmed
to the new Nor280
