Hughes & Kettner Montana Manual página 8

6.0 TROUBLESHOOTING
1) The MONTANA won't power up when you switch it on:
• It's not getting AC power. Check the mains cable to see if it
is connected properly or if there is a cut or crack in the
cable!
• The mains fuse is defective. Replace the fuse with another
identical fuse. If this fuse also blows, talk to your local Hughes
& Kettner dealer.
2) The MONTANA is cabled up and connected properly, but no
sound is audible.
• One or several volume or master controls are turned all the
way down. Dial in higher settings.
• A short in the speaker output caused one of the internal
fuses to blow. Have a qualified service technician locate
and eliminate the defect and change the fuse (ensure the
replacement fuse bears the proper rating).
• Your guitar cord may be defective. Try another cord.
• One of the patch cords connected to the serial FX loop may
be faulty. Unplug them-if the amp works fine, one of these
cords is defective.
• The FX MIX knob is turned up all the way but you haven't
connected a processor to the parallel FX loop. Turn the knob
counterclockwise as far left as it will go.
3) You have connected an effects device to the serial FX Loop
and the signal is totally distorted.
• The input of the effects device is being overdriven. You'll
have to lower its input sensitivity by turning down the input or
gain knob on the effects device.
4) You have connected an effects device to the serial FX Loop
and the output signal is significantly softer than without the
device.
• The output level of the effects device is too low. Turn up its
output knob.
