VLU11 Operation description
The VLU11 is a stolen vehicle recovery system (SVR), a single box enclosure incorporating a processor,
VHF Silent Radio Transceiver, GPS receiver, wireless data modem in addition to BLE chip transceiver,
vehicle-rated power supply.
VHF LoJack:
Transmits on a radio (RF) carrier frequency of 173.075 MHz.
There are two modes of operation for the low jack radio:
The tracking mode is activated whenever the vehicle is reported as stolen. In tracking mode the radio
transmits for 200 ms every 1 s.
Vehicles with the system installed send a 200 millisecond (ms) chirp every fifteen seconds on this
frequency when the car moves without a proper identification of the car key.
Under all other conditions the radio is in receive only mode.
The max power setting to the transmitter is as per settings used in testing and in the production is 33.62
dBm. The CC1125 low jack radio chip is set to 16 dBm output power. The power amplifier stage will
amplify by 17.5 dB.
The expected gain of the whip antenna is about -10 dBi.
Lowjack supports FSK modulation
BLE (Bluetooth LE): is optional and use 2.4GHz designed by CalAmp wireless network based on the Texas
instrument Chip CC2640 and operation range on 2402 - 2480 MHz bands and using Custom designed
antenna with peak gain of 5.36 dBi. The max power setting to the transmitter is as per settings used in
testing and in production is 0 dBm
The cellular connectivity: provided by uBlox Sara-R410M certified under grants below:
FCC ID: XPY2AGQN4NNN
ISED: 8595A-2AGQN4NNN
The module without modification as delivered by UBlox is used and hence the default module power
settings are delivered to the antenna.
The used antenna is also a custom design for the product with 2.58 dbi peak gain.
Regulatory Information
Human Exposure Compliance Statement Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations,
personal communications services (PCS) equipment is subject to the radio frequency radiation exposure
requirements specified in § 1.1307(b), § 2.1091 and § 2.1093, as appropriate.
CalAmp DataCom Inc. certifies that it has determined that the VLU11 complies with the RF hazard
requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24,
Subpart E of the FCC Rules and Regulations. This determination is dependent upon installation,
operation and use of the equipment in accordance with all instructions provided.
The VLU11™ is designed for and intended to be used in fixed and mobile applications. “Fixed” means
that the device is physically secured at one location and is not able to be easily moved to another
location. “Mobile” means that the device is designed to be used in other than fixed locations and
generally in such a way that a separation distance of at least 20 cm is normally maintained between the
transmitter’s antenna and the body of the user or nearby persons. The VLU11™ is not designed for or
intended to be used in mobile applications (within 20 cm of the body of the user) and such uses are
strictly prohibited.
To ensure that the VLU11™ complies with current FCC regulations limiting both maximum RF output
power and human exposure to radio frequency radiation, a separation distance of at least 20 cm must
be maintained between the unit’s antenna and the body of the user and any nearby persons at all times
and in all applications and uses.
FCC Rules and Industry Canada (IC) regulatory information
Compliance Statement (Part 15.19)
The VLU11 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.
Warning (Part 15.21)
Changes or modifications not expressly approved by CalAmp could void the user’s authority to operate
the equipment. Manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications to this equipment.
Compliance Statement (Part 15.105(b))
Note: 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 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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de
brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
Class B digital device notice “CAN ICES-3 (B)/NMB-3(B)” RF Radiation Exposure Statement
This equipment complies with the FCC/IC radiation exposure limits set fourth for mobile transmitting
devices operation in an uncontrolled environment. End users must follow the specific operating
instructions to satisfy RF exposure compliance. The equipment should only be used where there is
normally at least 20cm separation between the antenna and all person/user. 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.
Déclaration d'exposition aux radiations:
Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un
environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de 20 cm de
distance entre la source de rayonnement et votre corps.
Cet appareil et son antenne ne doivent pas être situés ou fonctionner en conjonction avec une autre
antenne ou un autre émetteur, exception faites des radios intégrées qui ont été testées.
