Use "Manual Hold" mode to time exposures manually using an external timer. The camera shutter opens when the "Start" button is pressed on the Promote Control, and closes on releasing the "Start" button. This mode is intended to mimic the behavior of a basic remote shutter release cord.
This mode requires the optional shutter cable. Please see Connections chapter for details.
1.Switch your Promote Control to the "Manual Shutter Hold" mode.
2.Set your camera exposure mode to "Manual".
3.Set your camera shutter speed to "Bulb".
4.Connect the Promote Control to camera via an optional shutter cable. No USB connection is required in this mode.
5.If you prefer to hold the button down for the duration of the exposure, set "Control" setting to "Hold Down" (default). If you would like to press and release the "Start" button and keep the shutter open, set it to "Toggle" instead.
6.Press the "Start" button on the Promote Control to open the camera shutter. The Promote Control shows the elapsed exposure time, and optionally, emits an audible signal every second the shutter is open. See Beep every second in manual hold mode setting description in Setup Menu to deactivate the audible feedback in "Manual Hold" mode.
If Mirror Lock-Up functionality is required in "Manual Hold" mode, press the "Start" button briefly to lock the mirror in the raised position, wait until the camera stops shaking, and then press the "Start" button again to start the actual exposure. If "Control" is set to "Toggle", you may need to press the "Start" button twice to raise the mirror and then press it for the third time to open the shutter
