NOTE
: The photocell is very sensitive but some experimentation with
positioning may be necessary to ensure reliable trigger, particularly if the
cell is not the direct line of sight of the triggering flash unit. Avoid directly
illuminating the photocell from a continuous light source (such as celling
lights or windows) since this can prevent correct operation. Very high
cellings can also affect the operation of the photocell.
6/ Audible Beep Settings
• Push the Beeper Button E (Fig. 1) to “ON” to give a short beep when the unit is ready to fire,
to provide an audible “Ready confirmation”.
NOTE
: Turning the switch E (Fig. 1) OFF will allow the modelling lamp to turn off the automatically
while the flash is fired.
7/ Flash Output
• The flash power output is variable over a 5 f-stops range (6 f-stops) from full to 1/32 in 1/10 f-stop
increments using two power regulator adjustment buttons A (Fig. 1) on the rear panel.
• The control has a minimum setting of 1.0 and a maximum setting of 6.0. Pressing the two regulator
adjustment buttons A (Fig. 1) will change the value by 0.1 f-stop /to give you a total of 50 values).
E.g. if the current value shown is 5.6 then to reduce the power by 1 f-stop just reduce it to 4.6.

8/ Changing the Flash Tube
8-1 Discharge the Flash Unit
• The charge in the flash unit must me discharged before removing the flash tube.
To discharge the flash unit:
1. Make sure the Flash unit is ON.
2. Push the red "TEST" button F on the rear panel of the Flash.

tube.
Note
: Use white cotton gloves or a clean cloth or glove to prevent fingers from
touching the flash tube.
8-2 Remove old Flash Tube
• First, remove the reflector. Then, using white cotton gloves or a clean cloth,
remove the modelling lamp. You will need to emove the retention spring wrapped
around the top of the flash tube. With needle-nose pliers, unhook the retention
spring loop. Using white cotton gloves or clean cloth, grip the base of the
flashtube on each side. Carefully pull the flash tube from the flash unit.
8-3 Install New Flash Tube
• Make sure the power switch is off and the power cord is disconnected
from the source. Locate the two flash tube pin sockets above the
modelling lamp socket. Using white cotton gloves or clean cloth,
push the pins off the flash tube into the sockets using firm,
even presurre at the base of the flash tube. With needle,
nose pliers, hook the retention spring over the hook
above the flash tube. Re-insert the modelling lamp
