Inserting the Batteries

Remove the Battery Compartment Cover (if) and insert 4 AA size batteries according to the diagram inside. (Caution: Incorrect insertion of the batteries will prevent proper operation of the flashgun, and may cause damage.)

Close the Battery Compartment Cover.

Attaching Your Flash to the Camera
Loosen the Lock Ring (4) . Insert the Mounting Foot (5) of your flash into the camera's accessory shoe clip. Tighten the flash with the Lock Ring.

Set the shutter speed of your camera to the proper setting for electronic flash use, or to 1/60 seconds. (Read your camera owner's manual for details on the flash synchronization.)4www.butkus.org

If your camera has a hot shoe contact, your flash is now fully synchronized with the camera through the center and off center contacts in the camera's shoe. In this case, the Synchro Cord is not necessary.

If the camera has no hot shoe contact, use the Synchro Cord Which comes with your flash unit.

Dedication System With CHINON Cameras

Used with Chinon CP-5, CE-5, CG-5, CE-4S or CE-4, the flash ready indicator in the viewfinder will glow signaling the camera and flash are ready to operate when the flash is fully charged and ready to fire.  Should a long time be needed for the viewfinder signal or flash ready light to become lit (over 30 seconds), new batteries will be needed soon.4www.butkus.org

Auto Shut-Off

Your flash is designed to automatically shut off the power supply to save the battery energy. When the unit is switched on, the F. Stop Indicator (6) and Distance Range Indicator (7) come on to indicate the start of charging. After some time, both indicators go off to indicate the power supply has shut-off and the charging stopped, if the unit is not operated. The Ready Lamp (9) stays on until the charged energy runs out. You can fire your unit as long as the Ready Lamp is on, and the unit, if fired, resets to the original state. A short push of the On/Off switch (Reset Button) (12) will also charge the unit again. (if neither the Ready Lamp nor the F. Stop Indicator come on after the On/Off switch is turned on, push the On/Off Switch to reset the flash unit.)4www.butkus.org

Bounce Photography
(this unit will not tilt or swivel, this is if you are able to have it off the camera with the flash sync cord attached)
Use bounce flash when you wish to achieve a softer effect and to eliminate the shadow on your subject. When taking flash pictures indoors, bounce the light off the white or reflective colored walls, ceiling or reflective flat surfaces.

For bounce photography, it is very important to remember that the automatic flash range should refer the total distance of flash to reflector to subject.

Hints for Maintenance and Better Flash Photography


The use of flash eliminates squinting and shadows and help bring out natural facial expressions on the subject. When taking pictures, against highly reflective surfaces like mirrors, glass or glittering water, use automatic operation.

When not in use, switch the unit off. Take the batteries out when the flash unit is being stored or when it will be carried for a long time. Keep your flash unit away from dust and moisture to prolong its life.4www.butkus.org

Do not try to open or repair your flash unit sirice the electric circuit inside carries a high voltage. If your flash needs repair or does not work correctly, take it to where you bought it from. Opening the unit voids the warranty.
