OJM-LTRT418CMDRemote Command Unit

The Linx RT-418-CMD Remote Command Unit is designed for general purpose remote control functions.The transmitter unit provides eight manually operated pushbuttons which send a fixed code upon depression.The transmitter may be paired with various Linx receiver modules to accommodate a variety of common periodic remote control functions. Battery replacement The remote unit utilizes a CR-2032 Button Lithium Cell.In normal use it will provide 1-2 years of operation.Access for replacement is accomplished by removing the screw in the middle of the back cover. Setting the transmitter address In order to allow the formation of unique Transmitter/Receiver relationships the transmitters address may be selected using internal DIP switches.The switches are accessed by removing the rear cover as for battery replacment. INSTRUCTION TOTHE USER 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 protec- tion 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 equipment has been certified to comply with the limits for a class B computing device, pursuant to FCC Rules.In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment.Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception.The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user's authority to operate this equipment.
