AF ILLUMINATORFOR AUTOFOCUSING(on DX Module OM/CN and FTA5000AF Module only)
Whenthe camera'soperatingbuttonis pressedhalfway,the AF illuminatoris automaticallyactivatedwhen required,
with low-contrastsubjectsin low light.This illuminationenablesthe camera'sautofocussystemto determinefocus
statusand adjustthe lens.
The AF illuminatorenablesautofocusingwith subjectsup to about 16 feet away.This distanceis for autofocusingonly.
Whenfocusingmanually,flashphotographyis possibleup to about71 feeI,when usingISO 100 and a f 1.4 aperture
(pleasereferTTL Auto Flashrangetable).
NOTE:. The workingrangefor the AF illuminatoris basedon a standardtest methodwith a 50mmlens.
lf longerfocallengthsare used,the cameramay not focusthe lensaccurately.In this case,
or wheneverfocussignalsblink,set focusmodeof the cameraswitchto M and focuslensmanually.
. On certaincameramodels,this AF assistlightis overriddenby the AF assistlighton the camera.
AUTO CHECK LAMP (When used with FTM5000/FTA5000 Module)
On TTL autoflashmodeor normalautoflashmode,if exposurewas sufficient,the auto checklampon the flashunit
will brieflyglowafterthe camera'sshutterbuttonis depressed.On normalautoflashmode,beforeactuallytakingthe
photos,you can checkwhetherthe shootingdistanceis withinthe automaticrangeby depressingthe test flashbutton
on the flashunit.
AUTO POWER-OFF
This flash unit incorporatesa batterysavingautomaticpoweroff circuit.The flash unit automaticallyturns itselfoff
approximately5 minutesafterthe lastoperationand the readyindicatorLED lampextinguishesitself.With the AF or
DX Moduleson somededicatedcameras,the flashcan be re-activatedfor firingby touchingthe shutterreleasebutton
on the camera.With othermodules,the flashcan be re-activatedfor firingby pressingthe ResetFlashButtononceon
the flashunitor by switchingthe flashunit OFF and then ON again.
. When used on certain digital cameras (Olympus/ Sony),the auto power-offfunction is controlled by the camera.
The flash unit can be automaticallyturned off only if the digital camerain use is switchedoff.

TTL AUTO FLASH OPERATION
This flash unit provides automatic Through-The-Lens (TTL) flash exposure when used with dedicated cameras
which have TTL Auto Flash Metering Circuitry.
This mode permits you to use any lens aperture within the flash unit's operating range to enable you to have greater
control over the depth of field. The larger the aperture (the smaller the f-number) you select, the greater the
maximum shooting distance (less depth of field but shorter recycling time between shots). On the other hand,
the smaller the aperture (the greater the f-number) you select, the lesser the maximum shooting distance
(greater depth of field but longer recycling time). Therefore, in selecting an aperture, all three factors - maximum
shooting distance, depth of field and flash recycling time should be taken into consideration.
(When simply demonstrating the TTL Auto function there must be film inside the 35mm SLR camera).

(2) Focus on your subject and note the flash 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.
