RKR Designs LLC Alpha 8410 Linear Amplifier User Manual
Introduction
•Although the Alpha 8410 meets international safety standards and
FCC regulations, remember that the equipment works with high
voltages that can be LETHAL!
This operating manual contains information, cautions, and warnings that
you must follow to ensure safe installation and operation. Read Chapter 1
before attempting to unpack or operate the Alpha 8410. Failure to perform
procedures properly may result in amplifier damage, fire hazard, or
electric shock.
IMPORTANT •NEVER open the amplifier case without unplugging the unit
from the wall outlet.
•NEVER touch an antenna during transmission.
•NEVER turn on the amplifier without the cover securely in
place and all attachment screws inserted.
•NEVER turn on the amplifier without a good ground
connection on the rear-panel ground terminal.
•NEVER turn the amplifier back on after a hard fault (that is, a
fault to power off) without waiting at least 20 seconds.
•NEVER cover or obscure the exhaust holes in the amplifier
cover. Never stick objects into the holes or allow liquids to
enter through the holes.
•NEVER allow key-down plate current to exceed 1.5 A for
more than 1 or 2 seconds. If you do and a plate current trip
occurs, it automatically resets in ~4 seconds if the amplifier
is returned to receive (key-up).
•NEVER allow the red GRID LED to stay brightly illuminated
for more than 1 second.
