Turning on the Power

About the Lock Function

By setting the power switch to <a>, you can disable flash’s button and dial operations. Use this to prevent the flash function settings from being accidentally changed after you set them.

If you operate a button or dial, <LOCKED> is displayed on the LCD panel (the functions displayed above function buttons 1 to 4, such as <[> and <@>, are not displayed).

About the LCD Panel Illumination

When a button or dial is operated, the LCD panel illuminates for 12 sec. When setting a function, the illumination continues until the setting is complete.

During normal flash shooting, wireless master flash shooting and master linked shooting, the LCD panel illuminates in green. If the Speedlite is a slave unit, it illuminates in orange.

You cannot use the test flash while the camera’s 3/1/2timer is operating.

The flash settings are stored even when the power is turned off. To retain the settings when replacing the batteries, replace the batteries within

1 min. of turning off the power switch and removing the batteries.

When the temperature of the flash head has risen due to continuous flash firing, the time until auto power off takes effect may increase.

You can fire a test flash while the power switch is set to the <a> position. Also, when a button or dial is operated, the LCD panel illuminates.
