CAUTION

This equipment is designed for operation in a horizontal position only, with mounting

brackets down. Do not operate in any other manner.

Because the Model 8327-300 Attenuator is a passive device and has no indicators or
controls, it requires no operating procedures or surveillance when the performance
limits are not exceeded. It should function faultlessly, absorbing and converting the
excess RF energy into heat indefinitely, if it is properly maintained and not subjected
to an overload.

Operation Under

Abnormal

Conditions

The Model 8327-300 Attenuator is not intended or recommended for outdoor use.
The Attenuator may be subjected to moderate overloads for limited periods of time
without overheating. However, this should be done cautiously, and it is strongly
recommended that if such a use is contemplated, the attenuator should be equipped
with a thermoswitch, P/N 2450-056. When interlocked with the power line to the
source of RF energy, the thermoswitch becomes a fail safe device to guard the
attenuator against the dangers of overheating.

WARNING

Never attempt to disconnect the equipment from the transmission line while RF power is

being applied. Leaking RF energy is a potential health hazard.

Shutdown

This attenuator, being a passive device, cannot be shut off. The source of RF energy
must be cut off instead.

Emergency

Shutdown

Turn off RF power at its source.
