- Shutter Release Modes: Supports single shot, continuous shooting, 2-second delay, and bulb (long exposure).
- Advanced Timer Functions: Includes delay timer, long exposure timer, interval timer, and exposure count settings.
- Bracketed Long Exposure (BKLN): Automatically captures a series of photos with varying exposure times, ideal for HDR imaging in low-light conditions.
- High Precision: Time settings are accurate to 0.1 seconds.
- Wireless Range: 2.4GHz radio transmission provides a reliable connection up to 60 meters.

5. Operating Instructions
The WTR2 offers various modes for controlling your camera's shutter. Use the Mode button to cycle through the available modes.
5.1 Basic Shutter Release Modes
- Single Shot: Press the Shutter Button halfway to focus, then fully to take a single photo.
- Continuous Shooting: Press and hold the Shutter Button fully. The camera will continue to shoot as long as the button is held.
- 2-Second Delay: Press the Shutter Button fully. The camera will fire after a 2-second delay.
- Bulb (Long Exposure): In Bulb mode, press the Shutter Button once to open the shutter, and press it again to close the shutter.
5.2 Timer Modes (Intervalometer)
The WTR2 allows for precise programming of various timer functions. Use the navigation buttons (Up/Down/Left/Right) to select parameters and the SET button to confirm.

Image 5.1: The WTR2 transmitter offers precise timing, accurate to 0.1 seconds.
- Delay (DELAY): Sets the delay time before the first exposure. Range: 0s to 99h 59m 59s.
- Long Exposure (LONG): Sets the exposure time for each shot. This is used in conjunction with your camera's Bulb mode. Range: 0s to 99h 59m 59s.
- Interval (INTVL): Sets the time between each exposure. Range: 1s to 99h 59m 59s.
- Number of Exposures (N): Sets the total number of photos to be taken. Range: 1 to 399, or unlimited (--).
5.3 Time-Lapse Photography
To set up a time-lapse sequence:
- Enter the timer mode on the transmitter.
- Set the DELAY if you need a starting delay.
- Set the LONG exposure time if using Bulb mode on your camera. Otherwise, set it to 0.
- Set the INTVL (interval) to the desired time between shots.
- Set the N (number of exposures) to the total number of photos or to unlimited (--).
- Press the Play/Stop button to start the sequence.

5.4 Bracketed Long Exposure (BKLN)
The BKLN function is useful for creating HDR images, especially in challenging lighting conditions. It automatically takes multiple exposures with varying exposure times.
- Enable BKLN mode on the transmitter (refer to the manual for specific button presses).
- Set the desired exposure bracketing steps.
- Press the Shutter Button to initiate the bracketed sequence.
