This function makes it possible to call the camera operator
without using the intercom. The camera operator is informed
of the call by the blinking of the tally lamp on the camera.
When the [CALL] button is pressed, the button light is lit and
the tally lamp on the camera blinks. Pressing the button
again turns off both the button light and the blinking of the
camera’s tally lamp.
Memo :
● The tally lamp on the camera does not blink or light when
either the camera or the RM-HP790DU/RM-HP790DE are
switched off. When the [CALL] button of the camera is
pressed, the [CALL] button of RM-HP790DU/RM-
HP790DE blinks in red.
The [TALLY] lamp on the front panel lights when signals are
applied to the [TALLY] terminals on the rear panel.
