AF ILLUMINATOR FOR AUTOFOCUSING
When the camera's operating button is pressed halfway, the AF illuminator is automatically activated
when required, with low-contrast subjects in low light. This illumination enables tlre camera's autofocus
system to determine focus status and adjust the lens.
The AF illuminator enables autofocusing with subjects up to about 16 feet away' This distance is for'
autofocusing only, when focusing manually, flash photograph is possible up to about 57 feet, when
using ASA 100 and F'1,4 aperture (please refer TTL Auto Flash range table.) -*
NOTE: The workingrange for the AF llluminator is based on standard test method with a 50 MM lens.
lf longer focal lengths are used, the camera may not focus lens accurately. ln this case or
whenever focus signals blink, set focus mode of the camera switch to M and focus lens manually.
AUTO CHECK LAMP
On TTL Auto flash mode or Normal Auto flash mode, if exposure was sufficient, the auto check lamp on
the flash unit glows at the same moment when the shutter button of the camera is pressed.
On Normal Auto flash mode, before actually taking the photos, you can check whether the shooting
distance is within the automatic range by pressing test flash button on the flash unit.
AUTO POWER.OFF
A battery-saving automatic power-off circuitry is incorporated in this flash unit. The battery power of the
.flash unit will be automatically turned off within approximately 5 minutes and the ready indicator LED
lamp extinguishes itself. With AF module on some dedicated mating cameras, the flash can be re-activated
forfiring by touching the shutter-release button of the camera. With other modules, the flash can be
re-activated for f iring by pressing once the Reset flash button on the f lastr unit or by switching the f lash
unit OFF and then ON again.

*mf.#b www.butkus.us TTL AUTO FLASH OPERATION
This flash Unit provide automatic Through-The-Lens (TTL) control of the flash exposure when used with
dedicated cameras which have TTL Auto Flash Metering feature.
This auto mode permits you to use any lens aperture within the flash unit's operating range to enable you
to have greater control over depth of f ield. The larger the aperture (the smaller the f-number) you select,
the greater the maximum shooting distance (the less the depth of f ield but the shorter the recycling time
between shots). On tlre other hand, the smaller the aperture (the greater the f-number) you select, the less
the maximum shooting distance (the greater the depth of field but the longer the recycling time).
f ield and flash Therefore, in selecting an aperture, all three factors - maximum shooting time, depth of recycling time should be taken into consideration.
The TTL Automatic mode of this flash unit balances the exposure between the main subject
illuminated by the f lash and the background in ambient light, whenever possible. Thus, this TTL mode
can be used underconditions ranging f rom total darkness to fill-in flash.

www.butkus.usNORMAL AUTO FLASH OPERATION
This f lash unit which has been attached to the non-AF module has three auto flash operation settings
rdesignated by the colours, BLUE - F2, YELLOW - F4, *GREEN - F5.6 on the Module forshooting
up to 40 feet,20 feet and 14 feet respectively when using ASA 100 f ilm.
* Non-AF Module CN does not have this setting.
BOUNCE PHOTOGRAPHY
The convenience of automatic operation can be applied to bounce lighting which involves "Bouncingt'
the light off a ceiling or other reflectivc surfaces to obtain soft illumination.
i. The auto mode can be used for bounce ligtrting (lt is recommended to operate your f lash in auto mode
for bounce f lash)
ii. After determining the position of your subject, adjust the bounce angle. The flash head is variable
from -7o to 90o and there are click stops at 0o,45o, 600,75o plus -7o position for straight-on f lash parallax correction.
When using bounce lighting, it is advisable to use a high speed film (ASA40O).

USING THE EXPOSURE CALCULATOR
(a) At Normal Auto Operation for Standard SLR Cameras.
(1) Set INDEX line of the ASA/DlN f ilm selector switch to the ASA/DlN speed of the f ilm in use.
l2l Read along the auto line (blue or yellow or green according to your auto range setting selected)
and find the correspondrng f-number for auto operation. Set thrs aperture on yourcamera.
(b) At TTL Auto Operation for Dedicated TTL Cameras
(1) Set INDEX line of the ASA/DlN film Selector Switch to the ASA/DlN speed of the film in use.
(2) Focus on your subject and note the f lash to subject distance.
(3) Locate the lens aperture your wish to use for TTL Auto Operation and read the distance opposite
this selected aperture to check whether the flash to subject distance iswithin auto range. lf it is, set the aperture on your camera.
(c) At Manual Flash Operation
(1) Set INDEX line of the ASA/DlN Selector Switch to the ASA/DlN speed of the fitm in use.
l2l Focus on your subject and note the f lash to subject distance. Locate this distance on the
distance scale.
(3) Read the aperture opposite this distance and set the f-number on your camera.
LOWER POWER MANUAL FLASH
At Manual Flash Operation, you can set the flash unit's Mode Selector Switch to'1116' power position,
which will give you faster recycling time and more number of flashes. lt is useful for close-up works and
the shooting with motor-drive f ilm winder (up to 2 frames per second). Guide number at this lower power
setting is 1/4 of the full power guide number (please see Guide Number Table).
