- For 'N' (Number of Shots), you can set it from 1 to 399, or to 'unlimited' for continuous shooting until stopped.
- Once all desired parameters are set, press the START/STOP Button to begin the timed sequence.
- To stop a running sequence, press the START/STOP Button again.

- If the remote will not be used for an extended period, remove the AAA battery to prevent leakage.
- Handle the connection cord carefully to prevent damage to the wires or connectors.
6. Troubleshooting
- Remote not responding: Check if the battery is correctly installed and has sufficient charge. Ensure the remote is switched ON. Verify the cable is securely connected to the camera.
- LCD display is blank: Replace the AAA battery. If the issue persists, ensure the remote is switched ON.
- Shutter not releasing: Ensure the camera is powered on and in a shooting mode (e.g., not in playback mode). Check camera settings for remote control compatibility. Ensure the remote's Shutter Release Button is pressed fully.
- Timed functions not starting: Ensure all timer parameters (DE, BU, INT, N) are set correctly and the START/STOP button has been pressed. Check if the remote is in LOCK mode.
