  • Page 4: Power Source

    POWER SOURCE The Retra Flash Pro Max uses 4x AA batteries (8x AA batteries with Booster) as the standard power source. The Retra Flash can work with single-use Alkaline batteries, however the performance will be greatly reduced. Take care of our planet and get the maximum performance from the Retra Flash by using high quality rechargeable NiMh batteries.

  • Page 5: Booster

    IMPORTANT: Use only NiMh or Alkaline batteries and NEVER use any other battery chemistry (NiZn, LiFe, Li-ion etc.) because the high current required for powering the Retra Flash can cause damage to the battery or result in fire or injury in case of catastrophic failure.

  • Page 6: Mode: Off

    In OFF mode the Retra Flash Pro Max has practically no battery consumption. Despite this, we strongly advise taking out the batteries, if the Retra Flash will not be used for several weeks or during travel, to avoid accidentally turning on the Retra Flash and consuming the battery.

  • Page 7: Mode: Batt/Test

    TEST MODE: By pressing the PILOT-TEST button in BATT-TEST mode the Retra Flash will emit a flash at the selected power level. This feature is used to test if your Retra Flash is firing correctly or for creative lighting techniques with long exposures.

  • Page 8: Mode: Sos/Turn

    The pilot light emits a morse code signal for help (SOS). This mode overrides all errors. When in the SOS/TURN mode, you can flip the screen on the Retra Flash Pro Max 180°. To turn the screen, simply turn the mode dial on the Retra Flash Pro Max to °.

  • Page 9: Charging - "Chg" Symbol

    CHARGING – “CHG” SYMBOL The Retra Flash will indicate that the capacitors are charging with a “CHG” symbol. Once the Retra Flash is ready to fire it will signal by producing a short sound and indicate the selected mode and power level.

Then press and hold the PILOT-TEST button for approximately 3 seconds or until the Retra Flash emits a sound.

  • Page 12: Mode: M - Manual

    Mode: M (Manual) In M mode, the Retra Flash is triggered via a built-in optical sensor. The power output of the flash can be adjusted manually, with the power dial. The power dial features 13 power levels with steps of approximately 0,5 F-Stop per step.

  • Page 13: Mode: Ttl (Automatic Illumination)

    Try setting the power dial to plus (+) positions OR decrease the distance from Retra Flash to subject. When using rear curtain sync in TTL mode, the Retra Flash will not fire in a range of shutter speeds from approximately 1⁄6 to 1⁄2, but will work at faster and slower shutter speeds.

  • Page 17: Mode: Hss - High Speed Sync Mode

    Mode: HSS - High Speed Sync mode The Retra Flash Pro Max is capable of emitting a long flash pulse required for HSS photography. The successful operation of HSS synchronization depends on the capability of underwater camera housing electronics OR the onboard camera flash to emit a HSS synchronized light pulse.
