Battery Level Indication

Note: When the LED light is on, the battery voltage is lower and the battery level indicator cannot display the correct amount.

Using the Flash

1. Power Management
   Press ON/OFF Power Switch for 2 seconds to power the ring flash on or off. Turn off if it will not be used for an extended period of time.

2. Power Control
   The flash output is adjustable from 1/1 full power to 1/128th power in 1/3rd stop increments.
   To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output.
   Turn the select dial to adjust the flash output and the rules are shown in the following table:
   Figures displayed when reducing the flash output level→1/1| 1/1-0.3| 1/1-0.7| 1/2| 1/2-0.3| 1/2-0.7| 1/4| •••| OF
   ---|---|---|---|---|---|---|---|---
   1/2+0.7| 1/2+0.3| 1/4+0.7| 1/4+0.3| •••

←Figures displayed when increasing flash output level

When the LCD panel shows “OF”, it means that there is no flash output and the flash cannot be fired.

3. M Mode
   Press MODE Selection Button (16) to enter M mode. In this mode, you can set the flash unit onto your camera hot shoe or your trigger hot shoe for firing. During shooting, adjust the power output and press the camera shutter, then the camera flash will fire a flash under the camera synchronous signal. In this mode, the light sensor is off.

4. S1 Mode: S1 Slave Triggering Mode
   Press Mode Selection Button (16) to enter S1 mode. In this mode, the flash unit can function as a slave flash for creating multiple lighting effects. It is respectively applicable to
   manual flash environment.
   In S1 mode, the flash unit will fire synchronously when the master flash fires, the same effect as that by the use of radio triggers.

5. S2 Mode: S2 Slave Triggering Mode
   Press Mode Selection Button (16) to enter S2 mode. In this mode, the flash unit can function as a slave flash for creating multiple lighting effects. It is respectively applicable to TTL system.
   In S2 mode, the flash unit will ignore a single “preflash” from the master flash and will only fire in response to the second, actual flash from the master.

6. RPT Mode: Stroboscopic Flash
   Press Mode Selection Button (16) to enter RPT mode. With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture multiple images of a moving subject in a single photograph.
   You can set the firing frequency (number of flashes per sec. expressed as Hz), the number
   of flashes, and the flash output.
   For setting procedures, see the following:
   • Press the Mode Selection Button (16) so that “RPT” is displayed.
   • Press Set Button (17) to select the item to be set. The item blinks.
   • Rotate Select Dial (20) to set the desired number.
   Calculating the Shutter Speed
   During the stroboscopic flash, the shutter remains open until the firing stops. Use the following
   formula to calculate the shutter speed and set it with the camera.
   Number of flashes / Firing frequency = Shutter speed
   For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter
   speed should be at least 2 sec.
   Note:
   • Stroboscopic flash is most effective with a highly reflective subject against a dark background.
   • Using a tripod, a remote switch, and an external power source is recommended.
   • A flash output of 1/1 or 1/2 cannot be set for stroboscopic flash.
   • Stroboscopic flash can be used with “buLb”.
   To avoid overheating and deteriorating the flash head, do not use stroboscopic flash more than 10 times in succession.Maximum Stroboscopic Flashes:Hz Flash Output| 1| 2| 3| 4| 5| 6| 7
   ---|---|---|---|---|---|---|---
   1/4| 30| 2| 2| 2| 2| 2| 1

7. Hi-Speed Sync Triggering
   To enter mode, press both Mode Selection Button (16) and LED Light Control Button(14).
   Press Mode Selection Button (16) again to exit mode.
   In hi-speed sync triggering mode, you can use a hi-speed sync trigger to have your flash unit synchronize with all shutter speeds of cameras(max. 1/8000 second, up to your camera). This is convenient when you want to use aperture- priority for fill-flash portraits.
   Note:
   • The hi-speed sync triggering mode is effective only when the flash unit is used together with the hi-speed sync trigger, e.g., Godox Cells II transceiver.
   • Hi-speed sync triggering mode is not available when the flash unit is mounted onto the camera hot shoe.

To avoid overheating or deteriorating the flash head, the over-temperature protection function will be activated automatically after 10 continuous high- speed flashes and the recycle time becomes 10s longer.
A number of flashes that will activate over-temperature protection in high-speed sync triggering mode:

8. LED Light Control
   Press the LED Light Control Button (14) to control LED light: Off→30%→70%→100%→ Off…… When the LED light is turned on, the icon is shown on the LCD display.

9. Buzz Function
   The buzz function can be controlled by pressing BUZZ Button (15). When the buzzer is turned on, is shown on the LCD display.

10. Wireless Control Function
    The flash unit is built-in with a Wireless Control Port (9) so that you can wirelessly control the on-and-off of your flash, modeling lamp, and buzzer, as well as adjust the flash output level, etc.
    • To control the flash wirelessly, you need a Godox FT series remote control set (on-camera and on-flash transceiver). Insert its receive end into the Wireless Control Port (9) on the flash and insert the transmit end into the camera hot shoe. Settings made on the hot-shoe-mounted transceiver and receive ends will be wirelessly communicated to the flash. Then you can press the camera shutter-release button to trigger the flash.
    • For full instructions on the use of FT series remote control, see its user manual.
    • When the flash unit receives wireless signals is shown on the LCD display.

11. Sync Triggering
    The Sync Cord Jack (10) is a Φ3.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.

12. PC Sync Triggering
    Insert one end of a PC sync cable into the PC Sync Socket (11) of the flash unit and the other end into the PC Sync Socket on the camera. The flash unit will fire when the camera’s shutter-release button is pressed.

Protection Function

Over-Temperature Protection
To avoid overheating and deteriorating the flash head, do not fire more than 40 continuous flashes in fast succession at 1/1 full power. After 40 continuous flashes, allow a rest time of at least 10 minutes. If you fire more than 40 continuous flashes and then fire more flashes in short intervals, the inner over-temperature protection function may be activated and make the recycling time about 10 to 15 seconds. If this occurs, allow a rest time of about 10 minutes, and the flash unit will then return to normal. When the over-temperature protection is started, is shown on the LCD display.

Number of flashes that will activate over-temperature protection:
