Flash Mode—TTL Autoflash
TTL Mode
* Press < MODE > Mode Selection Button and three flash modes
will display on the LCD panel one by one with each pressing.
This flash has three flash modes: TTL, Manual (M), and Multi
(Stroboscopic). In TTL mode, the camera and the flash will work
together to calculate the correct exposure for the subject and the
background. In this mode, multiple TTL functions are available:
FEC, HSS, second curtain sync, modeling flash, control with the
camera’s menu screen.
● When the shutter button is fully pressed, the flash will fire a pre-
flash that the camera will use to calculate exposure and flash
output the instant before the photo is taken.
● Press the camera release button halfway to focus. The aperture
and effective flash range will be displayed in the viewfinder.
Press < MODE > Mode Selection Button to enter TTL mode. The
LCD panel will display.
Setting FEC:
With FEC function, this flash can adjust from -3 to +3 in 1/3rd stops.
It is useful in situations where minor adjusting of the TTL system is
needed based on the environment.
FEC: Flash Exposure Compensation
● Turn the Select Dial to set
the amount.
Set the flash exposure
2compensation amount.
● “0.3”means 1/3 step,
“0.7”means 2/3 step.
● To cancel the flash
exposure compensation,
set the amount to “+0”.
Press Set Button again to

Shutter Sync Settings:
● Try not to use high-speed sync flash, for using this
function will reduce flash tube’s service life.
● Multi flash mode cannot be set in high-speed sync mode.
● With high-speed sync, the faster the shutter speed, the
shorter the effective flash range.
● Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
Note: In the wireless remote control mode, using high-speed
sync flash with Panasonic camera may occur out of sync.
1. High-speed sync: press the <SYNC> button and is displayed
on the LCD panel. Press the OK or button on OLYMPUS or
MENU button on PANASONIC camera to enter Flash Mode and
choose Fill-flash . Then, set the camera shutter.
2. Press OK or button on Olympus camera or MENU button on
Panasonic camera to set second-curtain mode. And set camera
shutter after mode is displayed.
2nd-C

The flash output is adjustable from 1/1 full power to 1/256th power
in 1/10th stop increments. To obtain a correct flash exposure, use a
hand-held flash meter to determine the required flash output.
M: Manual Flash
Press < MODE > button so
1that < M > is displayed.
Press the <+/-> button and turn
2the Select Dial to choose a
desired flash output amount.
Press Set Button again to
3confirm the setting.
Optic S1 Secondary Unit Setting
In M manual flash mode, press <S1/S2> button so that this flash can
function as an optic S1 secondary flash with optic sensor. With this
function, the flash will fire synchronously when the main flash fires,
the same effect as that by the use of radio triggers. This helps create
multiple lighting effects.
Optic S2 Secondary Unit Setting
Press <S1/S2> button so that this flash can also function as an optic
S2 secondary flash with optic sensor in M manual flash mode. This
is useful when cameras have pre-flash function. With this function,
the flash will ignore a single “preflash” from the main flash and will
only fire in response to the second, actual flash from the main unit.
● S1 and S2 optic triggering is only available in M manual
flash mode.
Turn the Select Dial to
3choose a desired flash
output.
● After you finish the setting,
press Set Button and all the
settings will be displayed.
Multi: Stroboscopic Flash
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.
With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
Press <MODE> button so
1that < > is displayed.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
For example, if the number of flashes is 10 and the firing frequency is
5 Hz, the shutter speed should be at least 2 seconds.
Number of Flashes / Flash Frequency = Shutter Speed
To avoid overheating and deteriorating the flash head, do not
use stroboscopic flash more than 10 times in succession.
After 10 times, allow the camera flash to rest for at least 15
minutes. If you try to use the stroboscopic flash more than 10
times in succession, the firing might stop automatically to
protect the flash head. If this happens, allow at least 15
minutes’ rest for the camera flash.
● Stroboscopic flash can be used with“buLb”.
● If the number of flashes is displayed as “--”, the firing will
continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown
by the following table.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic
flash.
● Using a tripod and a remote control is recommended.
● Stroboscopic flash is most effective with a highly reflective
subject against a dark background.
MULTI
● Press the Function Button
3 <Hz> to select the flash
frequency. Turn the Select
Dial to set the number.

Wireless Flash Shooting: Radio (2.4G) Transmission
The basic relative position and operation range are as shown in the
picture. You can then perform wireless TTL autoflash shooting just
by setting the master unit to <TTL>.
Using a flash (master/slave) with a radio transmission wireless
shooting function make it easy to shoot with advanced wireless
multiple flash lighting, in the same way as TTL autoflash shooting.
●The GIO1 O attach to the camera is called the master unit,
and a GIO1 O that is wirelessly controlled is called the
slave unit.
●You can also wirelessly control the GIO1 O set as the slave
unit with the transmitter ST-III O or ST-IV O (sold
separately). For details on setting the master unit functions,
see the transmitter’s instructions.
