3. Setup and Installation
Follow these steps to properly install your dash camera.
3.1 Mounting Location
Select a location on your windshield that does not obstruct your view of the road. The camera can also be installed on the rear glass, including nearly vertical rear glass found in minivans, by adjusting the mounting bracket.

3.2 Power Connection
Connect the included cigarette lighter plug cord to the dash camera and your vehicle's cigarette lighter socket. For a cleaner installation or to enable parking surveillance, consider using the optional direct wiring cord (HDROP-14) or connecting via a compatible COMTEC radar detector.
3.3 microSDHC Card Insertion
Insert the provided 8GB Class 10 microSDHC card into the designated slot on the dash camera. The device supports microSDHC cards from 8GB to 32GB (Class 10 recommended).
4. Operating Instructions
4.1 Basic Operation
The device automatically powers on and begins recording when the vehicle's engine is started (ACC power is supplied). It powers off when the engine is turned off.

4.2 Recording Functions
- Continuous Recording: Records footage from engine ON to OFF. Recording time varies based on video size and quality settings. By default, older footage is automatically overwritten when the recording limit is reached.
- Impact Recording: When the built-in G-sensor detects an impact, the relevant file (at the time of impact and the preceding or following file) is automatically saved as impact recording data. By default, older impact footage is overwritten when the limit is reached.
- Manual Recording: Pressing the designated switch allows you to record footage at any desired moment. The file at the time the switch is pressed and the preceding or following file are saved as manual recording data. By default, older manual footage is overwritten when the limit is reached.
- Time-Lapse Recording: This function compresses still images recorded at 1 frame per second into a short video, enabling long-duration recording. This mode is available during both normal operation and parking surveillance.
4.3 Parking Surveillance Function
To use the parking surveillance function, the optional HDROP-14 direct wiring cord must be connected. This feature detects impacts and records footage while parked, or performs continuous recording. Footage is saved to a dedicated parking surveillance folder for easy identification.
- One-Time Parking Surveillance Mode: Allows temporary activation of parking surveillance even if the function is normally set to OFF. Useful for specific situations when away from home.
- Parking Surveillance Mode Pass Function: Temporarily disables parking surveillance mode when parking in areas prone to false triggers, such as mechanical multi-story car parks, vibrating locations, or on windy days.
5. Advanced Features
5.1 HDR/WDR (High Dynamic Range / Wide Dynamic Range)
The HDR/WDR function corrects brightness differences, such as overexposure, and records stable images in various lighting conditions, including strong backlight. This ensures clear night footage.
5.2 GPS Functionality
The built-in GPS records your vehicle's driving speed and position information along with the video data. Date and time information is automatically corrected by GPS, eliminating the need for manual settings.
5.3 Noise Countermeasures
The product incorporates noise countermeasures to prevent interference with digital terrestrial broadcasting reception and navigation GPS reception.
5.4 Compatibility with LED Traffic Lights
The device reliably records traffic lights across different power frequency bands in various regions.
5.5 Radar Detector Mutual Communication (Optional)
When connected to a compatible COMTEC radar detector (requires optional ZR-13/ZR-14/ZR-17 cable), the following functions become available:
- Footage Confirmation: Review recorded video and audio on the radar detector's display.
- Operation Control: Adjust recording settings and perform operations using the radar detector's touch panel or remote control.
- GPS Information Acquisition: The dash camera acquires GPS information from the radar detector, recording vehicle speed and position.
- OBD2 Information Acquisition: Acquire accurate vehicle speed information from OBD2 via the radar detector, allowing speed recording even if GPS signal is lost. Dedicated viewer software can also display throttle opening, engine RPM, intake manifold pressure, and engine water temperature.
- Power Supply: Power can be supplied to the dash camera from the radar detector, simplifying wiring. Note: If the radar detector is connected via a cigarette lighter plug, the dash camera may restart in some idling stop vehicles when the engine restarts. Using optional HDROP-14 or HDROP-15 cables can prevent this.
5.6 Viewer Software
A dedicated viewer software is available for download from the COMTEC website. This software allows you to review recorded data on a PC, including video, audio, and G-sensor information. You can also convert recorded data to video or still images and save them to your PC.
6. Safety and Protection Features
6.1 Backup Function
In the event of a power cut due to an accident, the built-in supercapacitor helps prevent file corruption and protects the recorded footage.
6.2 SD Card Check Function
Upon startup, the device checks the microSDHC card for corruption. If an abnormality is detected, it will be indicated on the screen or via LED, preventing missed recordings due to a faulty card.
6.3 Emergency Recording Stop Function
In case of a significant impact from an accident, recording automatically stops. This prevents important footage from being unintentionally overwritten if the device powers on while moving the vehicle or during repairs.
- Impact detection sensitivity can be adjusted in 11 levels, including OFF.
6.4 Format-Free File System
The product utilizes a dedicated file system that prevents SD card fragmentation caused by repeated recording and deletion, unlike standard PC file systems (e.g., FAT). This eliminates the need for periodic SD card formatting.
7. Maintenance
7.1 Cleaning the Lens and Screen
Use a soft, dry cloth to gently wipe the camera lens and screen. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals or solvents.
7.2 microSDHC Card Management
While periodic formatting is not required, it is recommended to back up important footage regularly. If the card shows signs of degradation or errors, replace it with a new Class 10 microSDHC card (8GB-32GB).
8. Troubleshooting
- Device does not power on: Check the power connection. Ensure the cigarette lighter plug is securely inserted or the direct wiring cord is correctly installed. Verify the vehicle's power outlet is functional.
- No recording: Check if the microSDHC card is inserted correctly and not corrupted (refer to SD Card Check Function). Ensure there is sufficient space on the card.
- Poor video quality: Clean the camera lens. Ensure the windshield area where the camera is mounted is clean. Check video quality settings.
- GPS signal not acquired: Ensure the camera has a clear view of the sky. Avoid mounting near metallic objects that may interfere with the signal.
- Interference with other devices (e.g., digital TV, navigation): While noise countermeasures are implemented, some interference may occur in specific vehicle environments. Try repositioning the dash camera or its power cable.
If problems persist, consult the COMTEC website for further support or contact customer service.
