Description
FRONT PANEL (fig. 4-1) (Cont)
Six LEDs (red)
b. Off - Turns off signal. When the mode is
DPL or DPL Inv, returning the switch to Off
from Cont produces a 133 Hz tone burst
for a 120 ms duration.
c. Burst - For PL, tone A, and tone B modes the
output is present for as long as the switch Is
held in the burst position. For the A/B mode
the burst position causes a single signaling
sequence to be output. For the DPL and
DPL Inv modes the Burst position causes a
133 Hz tone to be output. For the Tone
Remote mode either the Burst or the Cont
position causes a tone remote access
sequence to be output. The access sequence
leaves tone A at a low level for transmit-type
commands until the switch is returned to the
Off position. This switch is spring loaded to
return to the Off position from the Burst
position.
When illuminated, indicates the selected mode of
the Code Synthesizer.
