BURST mode: Burst mode allows you to specify a group or
"burst" of Q-Switch pulses that fire sequentially with every
flashlamp pulse. These can range from one single shot to 999
Q-Switch pulses each time you press the "Q-Switch Start" button
on the Remote Box. Burst mode requires that the Q-Switch be
set to Internal sync.
To select Burst mode, position the cursor at "QS mode", then use
the "Increase\Decrease Value" buttons to change to "BURST" mode.
Finally press the "Enter Menu" button to show the QS BURST mode
menu. It contains the following items:

QS pulses: Use this item to set the number of Q-Switch pulses
that occur for each burst cycle. The range of acceptable values
for QS pulses is 1 to 999. When the flashlamp is running, the
set Burst mode will be used when the Q-Switch Start button on
the Remote Box is pressed. Below is a timing diagram for Burst
mode (QS pulse = 3):

SCAN mode: Select Scan mode to specify a group or "scan" of
Q-Switch pulses to be repeated for a predetermined number of times
or indefinitely. Each Scan consists of a group of active and passive
Q-Switch pulses. Scan mode requires that the Q-Switch be set to
Internal sync.
To adjust the SCAN parameters, from the Q-Switch menu, position
the cursor at the "QS mode" item. Use the "Increase/Decrease
Value" buttons to change to "SCAN" mode. Finally press the "Enter
Menu" button to show the QS SCAN mode menu.
