1. Improves issue of flash not firing because of sleep mode when shooting long exposures.
2. Improves possible misfire issues occurring after a flash has been fired at a high power level.
3. Test Button and Light Meters: Pressing the Test button on the transmitter will cause the flashes in A, B and C groups to fire simultaneously. Group(s) turned off will not fire.
When the flashes in A, B and C groups are set to Manual (M) mode, pressing the Test button on the transmitter will cause the flashes (which are powered on and on the same channel as the transmitter) to fire an initial low-power pre-flash. The flashes will fire simultaneously at their set manual power levels 2.5s later. This feature allows for light meters to be used correctly.
