Parts Illustration

Battery Installation

• When changing or installing the battery, make sure the mode knob is in the OFF position!

• Remove the Battery Cap by slowly rotating counterclockwise.

• Insert three 18650 lithium batteries with the polarity shown in the battery compartment.

• (Please note that this strobe requires three 18650 lithium batteries with a discharge current greater than 20A and a voltage of 3.7V. It cannot work with regular 18650 batteries.)

Operation

Mode Knob

• OFF Turns the power off. Switch mode knob to [OFF] when you don’t use the strobe.

• TEST In this mode, you can test the working status of the strobe. Press the mode knob to trigger the strobe.

• M Switch to M mode to set the light amount to Manual.
  Warning! Use M model power level 12, for high-speed continuous shooting over 100 times, which may cause aging of the coating on the dome and deformation of the internal structure. Please don’t use M mode for high- frequency continuous shooting. And only use a strobe underwater.

• AUTO SYNC Switch to AUTO SYNC mode when shooting with TTL flash output.

• M-HSS Switch the M-HSS mode when shooting with high-speed synchronization. (Warning! In M-HSS mode, please do not take more than 30 continuous shots within one minute !)

• MTL Switch to MTL mode when shooting in continuous mode. When using the strobe in MTL mode with a fiber connection, it supports 10 continuous shots per second at all power settings. When shooting in continuous mode using wireless trigger mode, the strobe may miss some flashes. The number of continuous shots supported under different power settings for MTL in wireless trigger mode are as follows.

2
3
4
5
6| 8/s
7| 6/s
8| 6/s
9| 5/s
10| 4/s
11| 4/s
12| 2/s

Do not use the MTL mode for continuous shooting when the battery level is at half or below!

• Target Light
  In modes other than the test mode, press the mode knob to turn on the target light. The target light has two colors, red and white, and each color has two brightness levels. Press the mode knob to change the color and brightness level.

• Wireless Trigger Mode

  • To use the wireless trigger mode, the Lumilink optical transmitter is required as the signal transmitter. When the strobe is turned on, the wireless trigger mode is disabled by default.
  • In modes other than the test mode, press and hold the mode knob for 2 seconds, and after hearing four “beep” sounds, the wireless trigger mode will be activated. (Wireless triggering is supported in M, M-HSS, and MTL modes)
  • Press and hold the mode switch for 2 seconds, and after hearing two “beep” sounds, the wireless flash mode will be deactivated.
  • The reception distance of the optical signal receiver underwater is 2 to above 10 meters up to visibility and brightness of sunlight (Under strong sunlight, the effective range of reception for the optical signal receiver is 60-70cm, with a reception angle of 50-60 degrees)

Strobe Indicator Light
The emission color of the strobe indicator light will change depending on the remaining battery level. Emission colors are shown in the table below.

• When the strobe indicator light is in a low battery state with a red light, please refrain from using the flash function to avoid damaging the battery.
• The strobe will preheat for 10 seconds when first turned on, during which the strobe indicator light will remain red. Please wait for the preheating to finish before using the strobe.
• When the strobe overheats, it will trigger an overheat protection mechanism, preventing further flash triggering. The strobe indicator light will become yellow, indicating the need for cooling for a few minutes.

Light Level Control Knob
The light amount can be adjusted in 12 increments:

M Mode

MTL Mode

The lifespan of the tube is tested through one million full-power cycles. To achieve the longest possible lifespan and safety, the electronic components of the Apollo III are designed with redundant power, which may result in instability of brightness during low-power flickering. At positions below the third level in M mode and below the sixth level in MTL mode, there will be minor variations in brightness.

Protective Cover Installation

Align the protective cover with the strobe as shown in the diagram.

Rotate the screw clockwise as shown in the diagram.

Mounting Ball Installation
