locking ring. Rotate the locking ring upwards. Push
the unit onto the 'Hot Shoe' socket of the camera and
rotate the ring downwards to lock the flash securely
to the camera.

the Sync Cord for the electrical connection.
4. Plug the micro phone jack end of the Sync Cord into
the sync socket of the flash unit located near the hot
shoe.
5. Insert the PC connector of the cord into the trigger
device like a wireless trigger receiver.
AUTOMATIC OPERATION
The flash unit is equipped with a built-in automatic
sensor to adjust the flash illumination for a perfect
exposure. The practical advantage is that you do not
have to change the f-stop on your camera lens within
the effective flash range. The flash also has 2 different
f-stops for different aperture settings on your camera
lens.
GOLD: Utilizes a wider lens opening for relatively
shallow depth of field, and provides greater automatic
operating range and better power conservation.
BLUE: Utilizes a smaller lens opening for greater depth
of field . Consumes more power.
SETTINGS TABLE USAGE
1. Select the ISO (ASA/DIN) speed row.
2. Adjust the flash zoom to the appropriate setting for
your lens focal length or zoom setting.
3. You will find the 2 different recommended f-stops,
one BLUE and one GOLD.
4. Set your camera aperture to your choice.
5. Set the Mode Selector Knob to the BLUE or GOLD
position to match your choice.
6. Within the effective flash range, the aperture of your
camera need not be readjusted.
For example, when the speed selection is ISO (ASA)
100 (DIN21) and your lens focal length (zoom) is 50mm:
GOLD: Camera Aperture = f 2.8
Automatic operating range 1.7m -10m (5-30ft)
BLUE: Camera Aperture = f 5.6
Automatic operating range 1.7m -10m (5-30ft)
