Operation

CAUTION

Do not operate this equipment over the rated 1000

watts continuously. Damage to the resistive element

will result.

The load has no indicators or operating controls, therefore it

requires no special operating procedures or surveillance

when the stated performance limits are not exceeded. Fol-

low the instructions pertaining to the specific transmitting

equipment.

Operation

Under

Abnormal

Conditions

WARNING

Using this load in the upper end of its power

dissipation range will cause the housing to become hot!

Care should be exercised in touching it.

These units will sustain an input moderately greater than

1000 watts for short periods of time. Such loading must be

spaced at reasonable intervals to allow sufficient time for

the load to cool to a safe temperature. The load can, for in-

stance, sustain an input of 1200 watts for a maximum of

five minutes with an interval of at least 30 minutes between

each power application.

Shutdown

These loads, being passive devices, have no way of being

turned off. Their source of RF power must be turned off in-

stead.
