We thank you for selecting Chinon flash unit.


Remove Battery Compartment Cover and insert AA size batteries according to the diagram inside.

Close the battery compartment

Caution: Incorrect insertion of the batteries will prevent proper operation of the flashlight, and may cause damage!

Insert the Mounting Foot of your flash into the camera's accessory Shoe Clip.

Set the Auto-Manual Control Switch to manual marked "M ".

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

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

If the camera has not the hot shoe contact, use the Synchro Cord which comes with your flash

Switch the flash unit on and take a picture after the Ready Lamp glows. The flash picture taking distance is indicated on the Distance Guide.

Formula for f-stop: Use this handy formula for figuring out the f-stop.

Guide Number - divided by - Distance = Lens Aperture (F-stop)

Ex. When using a ASA 100 film and standing 4.5m from a subject.

Set the lens f-stop to f4, (18 / 4.5 = 4).

Guide number is shown in Specification on the last page of this instruction manual.

When used for automatic flash photography, your flash automatically controls light output and sets the correct exposures for the subject within the automatic range. Once you set the aperture (f-stop) on your camera, there is no need to change it again while taking pictures within the available automatic range.

Set the Auto-Manual Control Switch to Auto marked "A".

Consult the exposure table on the back of your flash. The lens aperture of BLUE colored row are to be set according to the distance and the ASA or DIN film speed corresponding to the film in your camera.  (EX:  ASA 400, set your aperture to F8)

Slide the On-Off switch to "ON" and focus your camera. Take the picture after the Ready Lamp glows. {Note: If you have a flashmatic camera, you cannot use the automatic operation but have to follow the manual operation.)

The use of flash eliminates squinting and shadows and help bring out natural facial expressions on the subject. When taking pictures, avoid shooting into highly reflective surface like mirrors glass or glittering water.

If you have to shoot a subject with such reflectors behind, use the automatic operation for flash or shoot from a different angle so that any reflections do not directly go into the camera

When not in use, switch the unit off. Take the batteries out when the flash unit is being stored or when it will
be stored during a long time.

Keep your flash unit away from dust and moisture to prolong its life. It is a good idea to bring out your flash unit from storage and "TEST FLASH" it (about 10 times) once or twice a month.

Do not use Nickel Cadmium battery. (Webmaster: the new Alkaline rechargeables are fine)

Do not try to open or repair your flash unit since 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
