Operating Instructions
Normal
Operation
CAUTION
Do not operate this equipment over the rated 1000
watts continuously. Damage to the resistive element
will result.
These loads have no indicators or operating controls,
therefore require no special operating procedures or sur-
veillance when the stated performance limits are not ex-
ceeded. Follow 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 cooling to a safe temperature. They can, for in-
stance, sustain an input of 1200 watts for a maximum of
five minutes with an interval of at least 30 minutes be-
tween 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
instead.
