Rice Lake MSI-3460 Challenger 3 - Manual (Page 43)

RF Remote Control Option 39
The RF remote control is a narrow band low power device and does not have the
jamming immunity of the spread spectrum modem used by the MSI-3460 to
communicate to the remote display. Powerful sources of RF energy in the 418MHz
region can jam the remote and prevent it from operating. In this circumstance, trying
either of the two other available RF remote frequencies (433MHz and 315MHz)
might solve the problem. Before ordering the RF remote control option, some effort
to research RF devices used in the immediate area would be useful in avoiding
jamming the control signals.
It is the end users responsibility to confirm that the chosen operating frequency is
legal for use in your location.
In spite of the potential for jamming the remote control, the receiver is very immune
from false reception due to the 24 bit encoding. Therefore no functions will be
inadvertently executed.
6.6 Battery Replacement
The remote unit utilizes a CR-2032 button lithium cell.
In normal use it will provide one to two years of
operation. Access for replacement is accomplished by
removing the battery access cover by pressing down
firmly on the label area and sliding it off. Once the unit
is open, remove the battery by sliding it from beneath
the holder. Replace the cell with the same type while
observing the polarity shown. Once the new battery is
installed, both the transmitter and MSI-3460 will have
to learn new addresses. Follow both procedures for
setting addresses.

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
