Preparing/installing the device

Those operations may need the use of specific tools like:

T4 Torx screwdriver for the external screw.
T6 Torx screwdriver for the internal screw.
Small slotted screwdriver to remove the cover.
Thin tweezers to insert/remove the SIM card.

Open the device

Insert slotted screwdriver between top cover and body to pop-out the top cover on each side and extract it.
Opening the device

Remove the screw located on each side of the OBD connector using T4 Torx screwdriver.
Opening the device

Remove the screw located on the PCB at the bottom of the device using T6 Torx screwdriver.
Opening the device

Move apart the side of the device first and then pull the OBD connector out of the body.
Opening the device

Device is now open.
Opening the device

Properly close the device

First, insert the main part into the bottom cover. Insert the rear first and take care of the pogo pin of the GNSS antenna.
Once inserted, push the main part into the back cover until your hear two “clac”.
Place the long screw on the rear of the electronic cards in order to fix it to the body using T6 Torx screwdriver.
Place the screw on each side of the OBD connector to fix it to the body using T4 Torx screwdriver.
Insert the top cover beginning with the rear.
Finally, push the top cover down until you hear the “clac”.
Device is ready.

Install the OBD Dongle

Connect the OBD Dongle on your vehicle OBD connector.

LED sequences

The Dongle has a two-coloured LED, green and red.
Please note that when both LEDs are brightened, you can perceive the colour as orange.

Warnings and notices

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

Please read the installation guidelines, as well as the safety and operating instructions before operating your device. Follow all instructions and heed all warnings in the installation guide.

There is a risk of explosion if the battery is replaced by a wrong battery type. Please discard empty battery according to local regulations.

Dispose of used batteries according to the instructions.

FCC Regulations

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user ‘s authority to operate the equipment.

FCC RF Exposure Information (SAR)

This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the United States.

During SAR testing, this device is set to transmit at its highest certified power level in all tested frequency bands (and placed in positions that simulate RF exposure in usage near the bodywith the separation of 20 mm and on extremity with a separation of 0 mm.) Although the SAR is determined at the highest certified power level, the actual SAR level of the while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output.

The exposure standard for wireless employs a unit of measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC for body & head exposure is 1.6 W/kg.
The SAR limit set by the FCC for extremity exposure is 4.0 W/kg.

The FCC has granted an Equipment Authorization for this model device with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model device is on file with the FCC and can be found under the Display Grant section of www.fcc.gov/oet/ea/fccid after searching on FCC ID: A6GC4D-4G4USV8-3.

For this device, the highest reported SAR value for usage near the body is 1.37 W/kg. For this device, the highest reported SAR value for usage on extremity is 3.67 W/kg.

While there may be differences between the SAR levels of various devices and at various positions, they all meet the government requirement.

(SAR compliance for body operation is based on a separation distance of 20 mm between the unit and the human body.)

Industry Canada statement

This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions :
1. this device may not cause interference, and
2. this device must accept any interference, including interference that may cause undesired operation of the device.
This Class B digital apparatus complies with Canadian ICES-003.
This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter, except tested built-in radios.
The County Code Selection feature is disabled for products marketed in the US/ Canada.

Radiation Exposure Statement:

The product complies with the Canada portable RF exposure limit set forth for an uncontrolled environment and are safe for intended operation as described in this manual. The further RF exposure reduction can be achieved if the product can be kept as far as possible from the user body or set the device to lower output power if such function is available.
