Photogenic Professional Lighting Powerlight Manual (various) - Manual (Page 8)

Modeling Light:
The modeling light has three modes of operation:
1. MANUAL Press the ADJUST button to turn the MODEL yellow LED on. Adjust
the modeling lamp intensity using the 1/2 or 1/10 f-stops UP/DOWN arrow
buttons. Pressing the MANUAL button a second time will change the mode to
flash adjustment and is indicated by the illuminated red LED.
2. TRACK mode causes the modeling lamp intensity to track the FLASH setting.
The modeling lamp may be set to full intensity at any FLASH value, by simply
pressing the TRACK/SET button a second time, with the FLASH already set
to desired watt-seconds. Setting is retained when user returns from another
mode.
3. FULL ON/OFF. Press the FULL ON/OFF button to turn the modeling lamp OFF
(LED off) or ON (LED on) at full power.
All mode settings are retained, even after power has been turned off.
Test Function:
Press the TEST button to fire the flash tube for test purposes.
Flash Indication:
This function indicates the flash has fired properly. The flash indication feature will
dim the modeling light to its lowest setting, then intensify slowly to full brightness or
to its original state. This will occur after each flash, even though the modeling light
may be off. This feature is turned ON (LED on) or OFF (LED off) with the FLASH
INDICATION button.
Automatic Flash Dump:
This feature will automatically flash the unit when the FLASH setting is lowered;
otherwise, the internally stored power is discharged through a resistor, before the
unit is READY. Flash Dump is faster. This feature can be turned on or off, by the
user.
Turn FLASH DUMP on: Turn PowerLight AC power off. With unit power off, press
and hold the FULL ON/OFF button. While holding the FULL ON/OFF button,
turn the unit ON and wait until the FULL ON/OFF LED blinks. Release the FULL
ON/OFF button.
Turn FLASH DUMP off: Turn PowerLight AC power off. With unit power off, press
and hold the MANUAL button. While holding the MANUAL button, turn the unit
power on and wait until the MANUAL LED blinks. Next release the MANUAL
button and the MANUAL LED will go off.
Also, each time the AC line power is disconnected or switched off, the flashtube
will flash. This removes most of the flash capacitor charge to prolong the life of the
unit and is a much safer condition for storage, transporting, and replacement of
