5.1 Ein-/Ausschalten
To power on the MK-GT620S trigger and MK-R200 flashes, slide the power switch to the 'ON' position. To power off, slide the switch to 'OFF'.
5.2 Blitzmodi
The MK-MT24S supports various flash modes:
- TTL-Modus (Through-The-Lens): The camera automatically determines the flash output for correct exposure.
- Manual Flash (M) Mode: Allows manual adjustment of flash output from 1/1 to 1/64.
- Optische Slave-Modi S1/S2: The R200 flashes can be triggered by another flash. S1 mode triggers on the first flash, S2 mode ignores the pre-flash of a TTL system.

5.3 2.4-GHz-Funksteuerung
The MK-GT620S trigger communicates with the MK-R200 flashes via 2.4G wireless transmission. This system supports three groups (A/B/C) and four channels (1/2/3/4). The default ID is 0000. Ensure the trigger and flashes are set to the same group and channel for proper communication.
