Cleaning and maintenance of the receiver
Liquid possibly damages the electronic device of the receiver! The liquid may penetrate the enclosure and cause a short circuit of the electronic device. [Receiver must not come into contact with any liquid.]
- Before starting cleaning, please disconnect the device power.
- Regularly with a soft cloth to clean the equipment. Never allow the use of solvents or cleaning agents.
Tips and tricks
- to obtain the beat-receiving
- Transmitter’s effective signal range depends on the working environment and conditions, May be between 10 m and 100 m.
- Transmitting and receiving antennae should not be obstacles blocking the line of sight.
- When toor recept condition occurs in the receiver through the antenna cable connecting two separated antenna
- Transmitting and receiving antennas should keep a 5 m minimum distance. This can prevent the receiver of radio signal overshoot. – between the receiving antenna and steel or concrete wall should ensure the minimum spacing of 50 em and with V-shaped antenna calibration.
- in the multi-channel device operation
- When using multiple transmitters, the transmitter spacing should be too short to form a transmission line interference. The transmitters are to maintain at least 20 cm spacing.
FCC Warning:
This equipment has been tested and found to comply with the limits for a Class
B digital device, under 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 by the instructions, maycause harmful
interference to radio communications. However, there is no guarantee
thatinterference will not occur in a particular installation. If this
equipment does cause harmfulinterference to radio or television reception,
which can be determined by turning the equipmentoff 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 the receiver.
- Connect the equipment to 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.
Caution : Any changes or modifications to this device not explicitly approved by the manufacturer could void your authority to operate this equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 0cm between the radiator and your body.
