Using TTL (Through-The-Lens Metering)

TTL (Through-The-Lens Metering) is an automatic ash exposure that is predetermined by your camera’s

settings and internal light meter. TTL is most useful in rapidly changing lighting environments.

When the TTL shooting mode is selected with the Intert TTL remote, power adjustment on the remote will

change to a +/

display. The light output will be automatically set by the camera but can be ne-tuned using

exposure compensation. Exposure compensation can be set using the +/

power buttons on the remote.

Adjustments can be made in 1/10th stop increments up to +3 or

3 stops.

Charging the Battery

To check the amount of charge left on the battery, either press and hold the button on the battery indicator

on top of the battery, or turn the light to DC power mode with the battery inserted to view the LCD battery

indicator on the Intert S1’s LCD screen.

To charge the battery, remove it from the light by pressing together the tabs on both sides of the battery

and lifting straight up. Plug the included battery charger into the battery, then plug the charger into a wall

outlet to charge. There will be no indicator on the battery while charging, but the light on the AC converter/

charger will light up red while charging and green when completed. A full charge will take about 3 hours.

NOTE: Only use the included battery charger with your Intert S1 battery. Using other brand chargers could

damage the battery and will void its warranty.

Mounting to a Light Stand

Your S1 will mount to most standard light stands with a 5/8” stud. Unscrew the Stand Mount Knob until the

mount ts onto the light stand. Make sure to turn the Stand Mount Knob until tight.

Use the

Ratcheting Tilt-Lock to adjust the angle of the light on the stand. Once loosened, simply push

the light in the direction you want to tilt and it will click into place in increments. The resistance of the

Ratcheting Tilt-Lock provides extra security when using large, heavy modiers.

Replacing the Flash Tube and Frosted Glass Dome

Both the ash tube and frosted glass dome are user-replaceable*. Replacement parts can be purchased

through the Intert website or a certied Intert dealer.

*The oil from your ngers will damage ash tubes. Be sure to handle new ash tubes with gloves or clean cloth. Always

use caution when handling broken glass.

Firmware Updates

To ensure proper communication between the S1, the TTL remote, and your camera, make sure the rmware

on both your light AND remote are updated to the most recent version. The newest rmware updates are

available in the support section of the Intert website.

To check the rmware version on your light, power the light off, press and hold the “TEST” button, and

power the light back on. A number (1.5, 2.0, etc.) will appear on the LCD readout that corresponds to

the rmware version. To see which version of rmware your remote is using: power the remote on and

press and hold the “mode” button. A letter and number (b 01, b 02) will appear on the LCD readout that

corresponds to the rmware version.
