When used with RFLS-491HSRC, RFLS-96HSRC, RFLS-96HSARC, RFLS-496HSRC,
RFLS-496HSARC, RFLS-912HSRC, RFLS-912HSARC, or RFLS-91212HSRC
receivers, a range of ½ mile can be achieved. All inscriptions on the transmitter panel
are luminescent to facilitate use of the transmitter in a dark environment. The panel will
continue to glow for two to three hours after being exposed to a bright light source. The
transmitter’s commands are digitally encoded and amplitude modulated on a single
carrier frequency of 315 MHz (or 433.96 MHz in Europe). This frequency is synthesized
via phased-locked-loop from a quartz crystal for exceptional stability and immunity to
antenna proximity effects. No alignment or tuning procedures are ever required to
maintain optimum performance. The modulated RF output occurs continuously while a
transmit button is depressed. Resulting receiver output is continuous while the button
command signal is being transmitted. The command signal is transmitted by amplitude
modulating the carrier to indicate to the receiver which of the transmit buttons is
depressed.
The transmitter turns off its power automatically after 90 minutes of inactivity in order to
prevent accidental depletion of its batteries while in storage.
