Make sure the engine of the vehicle is turned off during installation. ■ Make sure the product is not installed in a location that blocks the view of the driver. ■ Install the product away from a location where the air bag is installed. ■ Make sure the movement of the steering wheel is not obstructed by the product installed. Selection of the installation location ■ Select the location of installation by referencing the image below. ■ Install the product slightly lower than the point where the gaze of the driver lands when facing forward. ■ Adjust the product so that the location of the face of the driver is level (i.e. both eyes) No. Recommended location On top of the dashboard (recommended) On top of the steering column cover 67 Installation (cradle bracket) (1) (2) ※ Lightly assemble the number 1 bolt on both sides, then assemble the number 2 Main body and cradle bracket How to install the product ■ Remove the front plastic cover. ■ Remove any foreign materials from the surface of the selected location. ■ Use the double-sided tape on the bottom of the holding dock to attach it to the location where you wish to install the product. Make sure the tape is attached firmly. (The product may move with long-term use of the product or the vibration coming from the vehicle. In such a case, the detection of movement may be undermined.) ■ For firm attachment of the product, use the bolt to attach the product onto the chosen location such as the dashboard of the vehicle. ■ Adjust the camera lens so that it faces the eyes. ■ Once the adjustment of location is complete, use the allen wrench to fasten the bolt for angle adjustment. ■ Connect SE1 power cable and GPS. 89 Product Features About the product ■ High-functioning ARM CPU ■ CMOS image sensor ■ USB 2.0 / UART interface ■ Circuits to protect from overvoltage/ overcurrent/ reverse voltage and minimization of noise ■ Algorithm for tracking and detection of the face and pupils ■ Certification acquried Main features ■ If the driver falls asleep during driving or takes his eyes off the street, it is immediately detected and triggers an alarm. ■ An Infrared ray LED is applied to allow for detection during night time and in dark places such as inside a tunnel ■ A special filter is built in to remove scattered reflection caused by sunlight. ■ Glasses or sunglasses are detected. ■ A three-color LED is applied to display the operation status (green/ blue/ red) ■ Micro speaker is applied to issue warnings ■ Compatible with all automobile models (DC 12/24V) ■ A dedicated holding dock makes it easy to install ■ Sound volume can be muted or adjusted in four levels. ■ Sensitivity can be adjusted in three levels. ■ Comparible with vibrating cusions (sold separately) ■ Firmware can be updated through the SD card. ■ All events and scenarios, as well as images, including drowsiness of the driver or eyes taken off the road can be saved on the SD card. ■ Can be synchronized with mobile apps, thanks to the application of BLE 89 Function description Not looking forward Not looking forward Eyes are on the road (normal driving) 1011 Function description Not looking forward Not looking forward Not looking forward Not looking forward Eyes are on the road (normal driving) Eyes are on the road (normal driving) ■ Depending on where the product is installed, it may not operate properly. ■ If the driver is wearing sunglasses or regular glasses that have special coating on the lens, detection may be undermined. ■ If there are hair strands that block the eyes, detection may be undermined. If it is before or after sunset/ sunrise, and depending on the light coming from the sides or outside, detection rate may vary. ■ A warning may be issued if the camera deems the driver’s eyes to be closed. (E.g. if the gaze is downward, if the eyes are squinted or if the eyes become smaller due to laughing.) 1011 Function description 1213 Function description About the buttons and GPS-related features ■ Switch to adjust volume and sensitivity - Volume can be adjusted by pressing the switch for a short duration (Sound can be muted or adjusted to levels 1 to 4). - Sensitivity can be adjusted by pressing the switch for a longer duration(Level 1 (low) / Level 2 (standard) / Level 3 (high)/ Default setting is Level 2.) ■ Alarm - GPS signals are picked up, leading to some warning alarms not being triggered when the car is stopped. - Alarms may not sound if the volume is set to 'mute' - In areas where GPS signals are not received, no speed can be picked up, resulting in the alarms not being sounded. - We recommend that the device be connected to GPS to make use of the full functions. (If the device is not connected to GPS, alarms may not sound.) 1213 Trouble shooting Product specifications 74.8 x 53.0 x 23.8mm 80g 60cm ~ 80cm Dashboard or steering column cover MAX 4W -20 ~ +60°C * Power source: Use a PS2 or less than 100 W power 1415 Warranty 1) FCC Compliance Statement This device complies with part 15 of the FCC rules.
