Correct Use of Inon Strobes

INON strobes are marvels of technology, offering multiple operating modes and compatibility with scores of camera/housing combinations. Unfortunately, all of that technology and versatility comes at a price.... complexity. Let's try to unravel a few of the mysteries.

Operating Modes:
Operating modes and strobe features vary by model. Your individual strobe may or may not have all of these modes or features.

Advanced Cancel Circuit

This feature is for use with External Auto and Manual Modes when using pre-flash type cameras. The circuit reproduces the camera’s pre-flash, but at higher intensity than the camera flash. This creates optimum underwater performance, faster recycle time for the camera flash, quicker follow-up shots, and longer camera battery life.

To accomplish this, the INON emits a pre-flash up to 22 times stronger than the camera pre-flash. The camera 'sees' this strong pre-flash, judges the subject to be close to the camera, and decreases the power (duration) of the main flash by the camera. The minimal main flash by the camera results in faster recycle time of the camera flash, and extended camera battery life.

If your camera does not fire a pre-flash, ACC must be disabled.

The ACC is ON by default, but can be disabled in one of two ways, depending on the model of strobe:

Strobes with a Magnet Hole Strobes with a Dial Switch
INON Magnet Style ACC Control INON Buton Style ACC Control
For models with a magnet hole type switch, insert the provided magnet and secure in place using the provided retaining screw to disable ACC. For models with a dial type switch, depress the dial and rotate to lock in the depressed position to disable ACC.

Aiming Light Control

Some models feature an aiming light (also known as a spotting or focus light).

This light can be activated one of two ways:

This light will automatically quench as the strobe fires, so it does not affect your exposure.
