Battery Warning:

Do not disassemble or open crush, bend or deform, puncture or shred
Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or other liquids, expose to fire, explosion or other hazard.
Only use the battery with a charging system that has been qualified with the system per CTIA Certification Requirements for Battery System Compliance to IEEE 1725. Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazard.
Replace the battery only with another battery that has been qualified with the system per this standard, IEEE-Std-1725. Use of an unqualified battery may present a risk of fire, explosion, leakage or other hazard.
Only authorized service providers shall replace battery. (If the battery is non-user replaceable).
Promptly dispose of used batteries in accordance with local regulations

Improper battery use may result in a fire, explosion, or other hazard.

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 body with the separation of 15 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-4G4USV8-2.
For this device, the highest reported SAR value for usage near the body is 1.30 W/kg. For this device, the highest reported SAR value for usage on extremity is 3.29 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 15 mm between the unit and the human body.)

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. MUNiC-C4D-4G4USAB-V8+OBD-
