7.4 SCHEMATIC
DIAGRAM
NOTE)
JP2: The terminal for switching Fc (carrier frequency of
the fixed code). This terminal is set at OPEN (Fc =
40kHz)
when
delivered.
If a product of another
manufacturer
accidentally receives the PIONEER
code, short the terminal so that Fc will be 36.7kHz.
(In which case, the learned code and preset code do
not change.)
This remote control saves the learned data, timing
data in ROM and other data (such as code data) in
RAM.
ROM
already contains the timing data for
other primary manufacturers.
JP3 is a terminal for
switching whether
or not to use that pre-loaded
timing data during learning.
This terminal is set at OPEN
when delivered. If
"data
is learned but the product does not operate,'
there is the rare possibility that learned timing data
is affected by the timing data for another primary
manufacturer in ROM, causing the receiving product
to be deactivated. In such a case, short JP3 to clear
all the learned data and restart data learning, so that'
the data precision is increased. (In which case, the
learned data in RAM is shared as is.)
