short circuit. When connecting other devices to this product, refer to
the manual for the product to be connected. The black cable is ground,
make sure to connect the ground wire rst.
Ensure that the ground cable is properly connected to metal parts of
the vehicles body frame or direct to the battery if your vehicle does not
have a grounded chassis frame. The ground cable of this units power
amp and a second powered system must be connected to the frame
separately with different screws. If the screw for the ground wire
loosens or falls out, it could result in re or malfunction.

This transmitter must not be co-located or operated in conjunction
with any other antenna or transmitter
be removed (or replaced) by user
FCC/ IC radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure
Guidelines and RSS-102 of the IC radio frequency (RF) Exposure
rules. This equipment has very low levels of RF energy that it
deemed to comply without maximum permissive exposure
evaluation (MPE). But it is desirable that it should be installed and
operated keeping the radiator at least 20 cm or more away from
person’s body (excluding extremities: hands, wrists, feet and
ankles). Alteration or modications carried out without appropriate
authorization may invalidate the user’s right to operate the
equipment.
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:
• Relocate or reorient 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.
