14 Model Lamp Selector
When pressed normally, changes model lamp modes:
• model lamps off (no mode selected)
• Auto: Each model lamp is proportional to the
flash power of each head:
10 is 100%, 9 is 50%, 8 is 25% etc.
• Auto Max: Each model lamp is proportional to
the flash power of each head, but there is always
one model lamp at 100%: the other model lamps
are proportionally lower.
• 100%
• independent: The level of each model lamp is
set using the up (9) and down (10) keys while
maintaining the model lamp selector pressed.
When held pressed, allows individual control of each
model lamp using keys 8, 9 and 10 and displays 7 and
11.

long as the “Test” button (17) or camera synchro
“X” (18) is held down. The display (16) will count
up.

from 10 (full power) to 6.0 (1/16 power) using the up and
down keys, with additional variation on each head: 2 f-
stops (PS-U 4), 1.5 f-stop (PS-Z 4) or 1 f-stop (PS-U 3)
