ABOUT DISTANCE DISPLAY
When you use the combination of MZ / Z series, and *ist film SLR cameras or PENTAX digital SLR
cameras with a lens which is produced after A series lens, the LCD panel of flash unit will indicate the
effective flash distance ranges. If you use an earlier series lens with these cameras, the effective
distance ranges will not appear on the LCD panel.
TTL AUTO FLASH
In the TTL AUTO Mode, the camera will control the amount of flash lighting to provide the appropriate
exposure for the subject.
1. Set the camera’s exposure mode to P (PICT) Mode.
2. Turn on the power switch of the flash, the TTL mark will appear on the LCD panel and flash will start
charging. (If TTL mark does not appear, depress the MODE button several times to select the TTL
mode).
3. Focus on your subject.
4. Check that the subject is located within the effective distance range, indicated on the LCD panel.
5. Press the shutter button, after the flash is fully charged.
When the flash is fully charged, the ready light in the viewfinder, and
appears on the flash unit.
◆ If flashgun is used with a P-TTL compatible camera, TTL will be
controlled by the P-TTL system. If the flash is set as TTL, “P" will be
displayed on the liquid crystal display.
◆ When the camera receives the appropriate exposure, the TTL icon on
the LCD panel will appear for 5 seconds. If this indication does not
appear, the flash illumination is not enough for that particular situation.
Please re-take the picture, at a closer distance. (In the case of digital
SLR cameras, “Flash Exposure Level” cannot be confirmed from the
camera’s viewfinder display or from the blinking display indicator of
the flash’s LCD panel. Please confirm the Flash Exposure
Level visually from the image that you capture.)
◆ The AF Auxiliary Light will turn on automatically as you focus on a subject in a dark area. The
effective range of the AF Auxiliary Light is up to about 0.7meter to 9meter (2.3-29.5 feet).
◆ When the flash is fully charged, the flash mark will appear in the finder. If the shutter is released
before the flash is fully charged, the flash will not fire, and the camera will take the picture at a slow
shutter speed.
