Rear Panel Features - Evh 5150III LBX-S Mode D'emploi

H. POWER INPUT: Connect included power cord to a
grounded outlet in accordance with voltage and frequency
ratings listed on rear panel of amplifier.
I. FUSE: With power disconnected, replace a blown fuse only
with one of the type and rating specified on rear panel of
amplifier.
J. POWER: Turns amp on and off. When first turning amplifier
on, leave OPERATE/STANDBY switch (K) in STANDBY (down)
position for 30 seconds while tubes warm, then set switch
to OPERATE (up) position to take amp out of STANDBY
mode. Before turning POWER switch off (down position),
put amp in STANDBY mode for 10 seconds
K. OPERATE/STANDBY: When taking a break from playing
and before turning amplifier off as noted above (J), put amp
in STANDBY mode—which helps prolong tube life—by
setting this switch to the STANDBY (down) position. Return
switch to OPERATE (up) position when resuming play after
a break. Also as noted above (J), amp should remain in
STANDBY mode for 30 seconds after initial power-up.
L. POWER LEVEL: FULL position provides maximum output
power; 1/4 position reduces power to approximately four watts.
CAUTION: To prevent electric shock hazard, do not connect to mains power supply while top cover is removed.
