necessary to have a cable Internet service to use your cable modem. If you are
already subscribing to cable TV, please make sure that you are also subscribing to
cable Internet service. If you do not have cable Internet service, contact your
cable TV provider and ask the following services.
yWhether they support two-way cable modem access service
or not.
☞The InfoRanger enables two-way data communication. If you want to use
all features of the InfoRanger, you need to subscribe to a cable TV
provider which provides two-way cable modem access service.

Internet services through the cable modem, you need to have cable
Internet service. Once you are an Internet service subscriber, your cable
TV provider will provide you with an Internet account, which you can
connect to via your cable modem. Please note that your Internet account
should be established before the installation of cable modem.

yRated frequency : 60Hz
While the InfoRanger is operating, keep the fluctuation range of input
voltage within 5% of regulated voltage. In addition, ground the electric
outlet which is connected to input terminal.
Avoid static electricity and electric noise….
Use preventive equipment if the InfoRanger is
installed in a place where high static electricity
or electric noise is present.
Clean and well ventilated place….

Direct sunlight can increase temperature of the
InfoRanger and this can cause damage to
operational parts and lead to operation failure.
Therefore, Samsung recommends keeping the
InfoRanger away from direct sunlight.
