8. SmarTab Cradle Installation
Mechanical Installation
Mounting Arm
The rear panel of the Micronet SmarTab cradle provides the mechanical infrastructure for a RAM® mount arm
installation.
The RAM® mounting arm is a flexible, rotating, arm-based mount that provides a wide range of fixed in-cabin positions
for maximum comfort and visibility. The mounting-arm screw-insert positions on the cradle rear panel are compatible
with AMPs standard mounting-arm products.
NOTE:
In-vehicle installation instructions must be provided by a qualified installation technician.
Mounting Inserts Location and Dimensions
There are two M5 thread mounting PEM Screw Inserts found on the rear panel of the Micronet SmarTab cradle. The
distance between the PEM screw inserts is 48.50mm.
Micronet provides with the Micronet SmarTab DTK two screws with the RAM® mounting arm (RAM® P/N RAM-B-138U)
with two screws. If you source the RAM mount arm or another mounting arm brand by yourself, you must take in
account the Mounting Arm Ball Base Adapter base thickness when calculating the screw thread length.

1. Determine the optimal positioning of the Micronet SmarTab cradle in the vehicle that provides easy access and a
clear view of both the road and the display.
2. Attach the base of the mounting-arm assembly to the dashboard or cabin.
3. Attach the mounting arm to the cradle rear panel using the mounting screw inserts.
4. Connect the Micronet SmarTab cradle with the mounting arm to the mounting arm base.
5. Follow the power cable preparation as described in Electrical Installation, on page 42.
Rev. 2 Micronet SmarTab - Hardware Guide 41 / 47
Electrical Installation
Vehicle Battery Connection
The Micronet SmarTab input power connects directly to the vehicle’s battery. See the Electrical Installation Figure 17
below.
The supported nominal battery voltage supply is 12V or 24V DC, with an operating range between 8V to 30V DC.
Figure 17: Electrical Installation Scheme
Rev. 2 Micronet SmarTab - Hardware Guide 42 / 47
Electrical Installation Procedure
1. Prepare the wiring for power, ground and ignition switch in the vehicle, for connecting to the Micronet SmarTab
cradle cable.
2. The power signal connects to the vehicle's power line protected by a 10A fuse. Add an inline 3A "Slow Blow" fuse
with fuse holder for HHC/HHD blade-type fuses to the power cable.
3. The ground signal connects to the vehicle's ground line.
4. The ignition input signal connects to the vehicle's ignition switch line.
5. Fix the cable after verifying that all the functions are performing properly.
6. Arrange the cab l es using a plast i c strip.
NOTE
The cradle must be connected to power before inserting the Micronet SmarTab into the cradle. If the
Micronet SmarTab inserted while the cradle not connected to power, the Micronet SmarTab shuts down
immediately.

9. Insertion to Cradle
Inserting the Micronet SmarTab into Cradle
1. Hold the Micronet SmarTab on top and insert it to cradle
2. Push the Micronet SmarTab on top against the cradle until you hear the click
Rev. 2 Micronet SmarTab - Hardware Guide 44 / 47
Removing the Micronet SmarTab from Cradle
1. Press the ORANGE latch knob on top of cradle.
2. Pull the Micronet SmarTab from cradle.

FCC Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
operate the equipment.
This equipment 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 radiate 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
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.

SAR Information Statement
Your Micronet SmarTab LTE is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission
limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government.
These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The
guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough
evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons,
regardless of age and health. The exposure standard for wireless mobile phones employs a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted with the phone
transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because
the phone 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. Before a phone model is available for sale to
the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government adopted
requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as
required by the FCC for each model. The highest SAR value for this model phone when tested for use at the ear is 0.5 W/Kg and
when worn on the body, as described in this user guide, is 0.77 W/Kg (Body-worn measurements differ among phone models,
depending upon available accessories and FCC requirements). The maximum scaled SAR in hotspot mode is 0.79W/Kg. While
there may be differences between the SAR levels of various phones and at various positions, they all meet the government
requirement for safe exposure. The FCC has granted an Equipment Authorization for this model phone with all reported SAR
levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model phone is on file with the
FCC and can be found under the Display Grant section of http://www.fcc.gov/ oet/fccid after searching on
FCC ID: U8O-STB5-LTE Additional information on Specific Absorption Rates (SAR) can be found on the Cellular
Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and Canada, the
SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard
incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in
measurements.
