INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY
THE FCC
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 generate 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 the 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 to an outlet on a circuit different from that to
•
which the receiver is connected.
Consult the dealer for technical assistance.
•
Do not install the repeater in explosive atmospheres
◆
(infl ammable gas, dust particles, metallic powders, grain
powders, etc.).
This repeater is intended for use as a fi xed base station with
◆
the antenna located outdoors on the rooftop or on an antenna
tower.
This repeater is designed for a 13.6 V DC power source.
◆
Never use a 24 V DC or higher source to power the repeater.
Use only the supplied DC cord.
◆
Do not remove the ferrite core attached to the DC cord. Doing
◆
so may cause interference with radio communications.
Do not put anything on top of the repeater. This will obstruct
