Installation
The HDR-101 offers flexible mounting options to suit your vehicle's interior. It can be installed either behind the rearview mirror or on the dashboard.
- Choose a Mounting Location: Select a position that does not obstruct your view of the road or interfere with airbags. Common locations are behind the rearview mirror for a discreet installation or on the dashboard for easier access.
- Clean the Surface: Use the provided cleaning wipe to ensure the mounting surface is free of dust and grease.
- Attach the Mounting Bracket: Apply the adhesive mounting tape to the bracket and firmly press it onto the chosen surface.
- Attach the Drive Recorder: Slide the drive recorder onto the mounting bracket. Adjust the camera angle using the hex wrench to ensure a clear view of the road ahead. The device features automatic display inversion, allowing for dashboard mounting without affecting screen orientation.

Power Connection
Connect the cigarette lighter power cable to the DC12V/24V port on the drive recorder and plug the other end into your vehicle's cigarette lighter socket. The device will power on automatically when the vehicle's ignition is turned on.
Initial Configuration
- microSD Card Insertion: Insert the provided microSDHC card into the microSD card slot until it clicks into place. Ensure the card is inserted correctly to prevent recording errors.
- Time and Date Setting: Upon first use or after a power reset, you may need to set the correct time and date. Navigate through the menu using the UP/DOWN buttons and confirm with OK.
Operating Instructions
Recording Modes
The HDR-101 supports multiple recording modes to capture various driving situations:
- Continuous Recording: The device automatically records video from the moment the power is turned on until it is turned off. When the microSD card is full, the oldest files are automatically overwritten.
- G-Sensor Impact Recording: In the event of an impact or sudden braking/acceleration, the built-in G-sensor detects the event and automatically saves the corresponding video segment as an impact recording. These files are protected from being overwritten by continuous recording. The G-sensor sensitivity can be adjusted (11 levels, including OFF).
- Manual Recording: You can manually initiate a recording by pressing a designated button. This allows you to capture specific events or moments on demand.
Viewing Recordings
- On-Device LCD: Recorded videos can be immediately viewed on the device's 2.5-inch LCD screen. This is useful for checking footage on the spot or adjusting the camera angle during installation.
- PC Playback: Remove the microSD card and insert it into a computer (using the adapter if necessary). The COMTEC PC viewer software (usually pre-loaded on the microSD card or available for download) allows for detailed playback, including G-sensor data and other recording information.
- TV Output: Connect the device to a TV using an optional AV cable to view recordings on a larger screen.

Other Functions
- Audio Recording: The device supports simultaneous audio recording with video.
- Backup Function: In the event of a power interruption (e.g., engine off), the device has a backup power function to save the currently recording file, preventing data loss.
- LED Signal Light Compatibility: Designed to record LED traffic signals accurately.
- Calendar/Clock Display: The LCD screen displays the current date and time.
Maintenance
microSD Card Management
To ensure reliable recording and prevent data loss, it is recommended to periodically format the microSD card. The device performs a check on the microSDHC card upon startup. If an error is detected, a warning will be displayed on the LCD screen, helping to prevent recording omissions due to card damage.
Troubleshooting
If you encounter issues with your HDR-101, consider the following:
- No Recording/Recording Errors: Check if the microSD card is properly inserted and not damaged. Format the card if necessary.
- Interference with Other Devices (e.g., Digital TV, GPS): The HDR-101 is designed with noise countermeasures to minimize interference. If interference occurs, ensure the power cable is properly routed and not near sensitive antennas.
- Incorrect Time/Date: Reset the time and date through the device's menu.
- Poor Video Quality (Night): Night recording quality depends on ambient lighting. In very dark areas, visibility may be limited.
