TJFC433 is a very beautiful appearance of the 1527 learning remote control,
the shell, using imported high-quality flame-retardant ABS material
production, metal outer ring can prevent damage, panels and buttons give a
very good texture, safe and reliable use. It uses a surface acoustic resonator
and a high-power RF circuit. The circuit consumes current only when the
button is pressed. It does not consume power at ordinary times. It is simple
to use and can work with the common ASK super-regeneration or
super-heterodyne receiving circuit, it has high frequency stability。
