1. Introduction and Overview
The JJC TM-C Intervalometer Timer Remote Control Shutter Release is designed to provide photographers with enhanced control over their camera's exposure settings. This device offers specialized functions including self-timer, continuous shooting, long exposure, and interval shooting, making it ideal for various photographic applications such as time-lapse sequences of natural phenomena or long-exposure night photography.
It allows precise setting of timer delays, exposure times, and intervals up to 99 hours, 59 minutes, and 59 seconds, adjustable in one-second increments. Users can also specify the number of shots from 1 to 399, or set it for an unlimited number of photos. The unit can also function as a basic manual remote shutter release without batteries, allowing for half-press autofocus and full-press shutter release. In bulb mode, the shutter release button can be locked to keep the shutter open until released.

5. Operating Instructions
The intervalometer features four main programmable settings: SELF (delay), BULB (exposure time), INTVL (interval), and NO. (number of shots).
- Setting Parameters:
- Use the cursor control buttons (▲ / ▼) to navigate between SELF, BULB, INTVL, and NO. settings.
- Press the SET button to select a parameter for adjustment.
- Use the cursor control buttons (◄ / ►) to move between hours, minutes, and seconds.
- Use the cursor control buttons (▲ / ▼) to adjust the values.
- Press SET again to confirm the setting.
- Parameter Definitions:
- SELF (Delay): The delay time before the first shot is taken (1 second to 99 hours, 59 minutes, 59 seconds).
- BULB (Exposure Time): The duration of each exposure (1 second to 99 hours, 59 minutes, 59 seconds). This setting is only active if your camera is in Bulb mode.
- INTVL (Interval Time): The time between the start of one exposure and the start of the next (1 second to 99 hours, 59 minutes, 59 seconds). Important: The interval time must be longer than the exposure time (BULB) as it includes the exposure duration.
- NO. (Number of Shots): The total number of pictures to be taken (1 to 399, or unlimited).
- Starting a Sequence:
After setting all desired parameters, press the START/STOP button to begin the shooting sequence. The display will show the remaining time and shots.
- Stopping a Sequence:
To stop an ongoing sequence, press the START/STOP button again.
- Manual Shutter Release:
Even without batteries, the intervalometer can function as a basic wired remote shutter release. Half-press the shutter button for autofocus, and fully press it to take a picture. For bulb exposures, slide the shutter release button upwards to lock it, keeping the camera's shutter open until you slide it back down to release.

Figure 6: Example demonstrating how to set Bulb and Interval times. If Bulb time is 10s and desired interval is 5s, the INTVL setting should be 15s (10s exposure + 5s interval).
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the intervalometer. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use for extended periods, remove the AAA batteries to prevent leakage and store the device in a cool, dry place away from direct sunlight.
- Cable Care: Avoid sharp bends or kinks in the connecting cable to prevent internal wire damage.
- Battery Replacement: Replace batteries when the low battery indicator appears on the LCD screen or when the device's functions become unreliable.
7. Troubleshooting
Here are some common issues and their solutions:
| Problem | Solution |
|---|---|
| Remote does not power on. | Check if batteries are inserted correctly and are not depleted. Ensure the ON/OFF switch is in the "ON" position. |
| Timer settings reset to 0 after turning off. | This is normal. The intervalometer does not have a memory function for settings. You need to re-enter settings each time it's powered off. |
| Interval time cannot be set shorter than Bulb time. | The interval time includes the exposure (Bulb) time. Therefore, the interval must always be equal to or longer than the Bulb time. Adjust your Bulb time or increase the interval. |
| Camera does not trigger. | Ensure the cable is securely connected to both the intervalometer and the camera. Verify camera compatibility. Check camera's remote settings if applicable. |
| Cannot control video recording or lens zoom. | This intervalometer is designed for still photography functions (shutter release, timing). It does not support video control or lens zoom functions. |
| Need to change camera settings during time-lapse. | You can change camera settings during a time-lapse. It is advised to do so during the interval period (when the shutter is not open) to avoid camera shake affecting the photo quality. |
| Longest time-lapse duration. | The maximum programmable time is 99 hours, 59 minutes, 59 seconds. It cannot be set for daily or longer durations automatically. |
