Features
Supports detachable front panel products. System chips:
LC7233N, LC75853E/W and LC7538JMD
Supports anti-theft LED flashing and reminder to
remove panel alarm functions.
Supports control of an electronic tone/volume control IC
(the LC7538JMD). Functions: bass, treble, balance,
fader
Muting function (with key, out and electronic tone
controls)
Supports two color illumination control (dual systems).
Reduced LCD display output pin count achieved by
operating at 1/3 duty and 1/3 bias drive using the
LC75853E/W.
Up to 36 stations can be stored in preset memory: 6
stations for each band (FM1, FM2, FM3, VF, MW
(MW1) and LW (MW2)). Previous station function also
supported.
Auto preset memory function
Radio monitor output: operates during tape FF/REW.
CD function (with key, in, and out)
Tape function (Flashing direction display supported
when FF and REW signal inputs are provided.)
