2. Key Features

The COMTEC ZERO 700V is equipped with a range of advanced features to provide comprehensive traffic information and alerts.

2.1. Mobile Small Orbis Support

The device provides alerts for mobile small orbis (speed cameras) that can be set up in locations previously difficult to monitor, such as residential streets. Warnings are displayed using maps and actual images.

Figure 2: Example of a Mobile Small Orbis alert display. The screen shows a map and a real-world image indicating the approaching enforcement point.

2.2. Roundabout (Circular Intersection) Support

The ZERO 700V alerts you to roundabouts, which are circular intersections without traffic lights or stop signs, to help you pay attention to the direction of travel. Note that some roundabouts may still have temporary stop regulations.

Figure 3: Example of a Roundabout alert display, showing a graphical representation of the intersection.

2.3. New Traffic Regulation "Zone 30" Support

The device supports the new "Zone 30" traffic regulation, which limits the maximum speed to 30 km/h in areas with dense residential roads. When entering such an area, the device provides alerts via a warning screen and announcements. An icon is displayed while driving within the zone.

2.4. BrilliantLED Illumination

BrilliantLED flashes provide clear and easy-to-understand alerts. The LED color can be selected from 5 options to match your vehicle's interior illumination. It can also be set to light up or flash in conjunction with vehicle speed or alerts.

2.5. Glonass & Michibiki Reception & Fastest GPS Positioning

In addition to traditional GPS, the device supports reception from quasi-zenith satellite Michibiki, Glonass, Himawari, and GAGAN. The number of receivable satellites has increased to 59, significantly improving reception accuracy and speed.

2.6. OBD2 Connection Support

When connected to an optional OBD2 adapter (sold separately), the device can display up to 6 patterns and 138 items of vehicle information. OBD2 connection also allows for accurate vehicle speed acquisition, preventing loss of vehicle position even when GPS signals are interrupted in tunnels.

2.7. 3-Interface Operation

Operation is enhanced with three interfaces: remote control, touch panel, and touch switches. The device can be operated using only the main unit even without the remote control.

2.8. Basic Performance

• 3.2-inch wide MVA LCD: Offers significantly clearer display and wider viewing angles compared to TFT LCDs.
• G-sensor/Gyro sensor/Brightness sensor equipped.
• Compatible with idling stop vehicles and hybrid vehicles.
• Supports Toyota hybrid display.
• Free monthly updates for GPS data and public enforcement information.
• Industry-leading 18 reception bands.
• Over 39,000 enforcement and inspection data points recorded.
• Brightness Sensor ON/OFF switchable: Automatically adjusts LCD brightness based on external light, reducing glare in tunnels or underground parking.
• Auto Mode function: Automatically distinguishes between general roads and highways to cut unnecessary alerts.
• Super high sensitivity triple engine: Equipped with super high sensitivity GPS, radar, and wireless for accurate reception.
• Radar Cancel Point Detection: Automatically recognizes locations that receive false radar signals (e.g., automatic doors) and allows registration as false alert points. Alerts are muted when passing these registered points again.
• Opposing Lane Orbis Radar Cancel Function: Automatically mutes alerts if radar waves from opposing lane orbis or H-systems are detected, recognizing them as opposing lane enforcement.

6. Troubleshooting

6.1. No Power

• Check if the power cord is securely connected to both the unit and the cigarette lighter socket.
• Ensure the ON/OFF switch on the back of the unit is in the 'ON' position.
• Verify that the vehicle's cigarette lighter socket is functioning.

6.2. No GPS Signal

• Ensure the unit is mounted in a location with a clear view of the sky, away from metallic objects or tinted windows that may block signals.
• Allow sufficient time for the unit to acquire GPS satellites, especially after initial setup or moving to a new location.

6.3. Frequent False Alerts

• Utilize the Radar Cancel Point Detection feature to register locations with known false signals (e.g., automatic doors).
• Ensure the Auto Mode function is enabled to differentiate between general roads and highways, reducing unnecessary GPS alerts.
• Check settings for radar sensitivity and adjust if necessary.

6.4. microSD Card Error

• Ensure the microSD card is inserted correctly and fully into the slot.
• Try reformatting the microSD card (this will erase all data, so back up if necessary) or using a different compatible microSD card.
