a. Replacing the head
1. After replacement, demagnetize the heads by using
a degausser.
2. Be sure to clean the heads before attempting to make
any adjustments.
3. Be sure both channels (1 and 2) are the same level.
(Using a dual-channels oscilloscope).
4. All wiring should be returned to the original position
after work is completed.

CD PICK-UP MAINTENANCE
About pick-up (Optical lens) Cleaning
Clean a lens with swab of the cotton which moistened it with alcohol, cleaning paper or cleaning disc appointed.
Specified cleaning disc : LC-1 (Part code : 645 026 1961 ..... manufactured by SANYO.)
Show a clean procedure in the following in reference by swab of cotton.
1. Cotton swab is wrapped with Cleaning paper.
2. Add the isopropyl alcohol.
3. Gently move the tip of cotton swab just like a draw a whirlpool from inside to outside on the surface of lens.
• Use a plastic screw driver for adjustments.

PE2 20 O
PE2 is an open-drain output port. A pull-up resistor between this port and VDD
is required.
In backup mode, PE2 goes to the high-impedance state.
After a reset, it remains at the low level until an output instruction is executed.
PE3/BEEP 19 O
General-purpose output or beep tone output shared-function port.
The BEEP instruction is used to switch between the general-purpose output
and beep tone output functions.
To use this port as a general-purpose output port, execute a BEEP instruction
with b3 =0 to set up the general-purpose output function. If b3=1, the beep tone
output function will be selected. Bits b0, b1, and b2 select the beep tone
frequency.
The LC723341E provides seven beep tone frequencies.
* : When the PE3 port is set to the beep tone function, executing an output
instruction only switches the state of the internal output latch and has no
effect on the beep tone output.
In backup mode, this port goes to the high-impedance state. This state is
maintained until either an output instruction or a BEEP instruction is excuted.
After a reset, the general-purpose output port function will be selected.
PF0/ADI0 24
PF1/ADI1 23
PF2/ADI2 22
PF3/ADI3 21
General-purpose input or A/D converter input shared-function ports.
The IOS instruction (PWn=FH, b0 to b3) is used to switch between the general-
purpose input and A/D converter input functions.
The function can be switched in 1-bit units. (0:general-purpose input, 1:A/D
converter input) When the A/D converter input function is selected, the pin to be
A/D converted is selected with the IOS instruction (PWn=1).The A/D converter
is started with the UCC instruction(b3=1, b2=1). The ADCE flag is set when the
conversion completes. The INR instruction is used to read out the data.
* : Since CMOS input is disabled, the data read out will always be zero if an
input instruction is executed for a port pin set to analog input mode.
Execute an IOS instruction (PWn=0, b0 to b3) to set the port that clears
backup mode.
In backup mode, this ports goes to input disabled high-impedance state. After a
reset, the general-purpose input port function will be selected.
The conversion time for the 6-bit successive approximation A/D converter is
0.64 ms. The A/D converter full-scale voltage is 63/96 of VDD.
I
General-purpose I/O ports. *1
The IOS instruction (PWN=4) is used to switch between the general-purpose
input and output port functions. The I/O direction can be set in 1-bit units.
(0:input, 1:output) In backup mode, this port goes to the input disabled
high-impedance state. After a reset, the general-purpose input port function will
be selected.
I/O
I/O
General-purpose I/O ports. *1
The IOS instruction (PWN=5, bo, b1) is used to switch between
the general-purpose input and output port functions. The I/O direction can be
set in 1-bit units. (0:input, 1:output) Two of these port pins can be used as
external interrupt inputs. In that case, the I/O direcrtion must be set to input, and
rising or falling edge detection must be selected with an IOS instruction
(PWN=3, bo, b1).
In backup mode, this port goes to the input disabled high-impedance state.
After a reset, the general-purpose input port function will be selected.
4.5MHz crystal oscillator circuit connections.
I
These input ports are used as key return ports and are designed with a low
threshold voltage. When a key matrix is formed with the PB port, multiple key
presses with up to 3 keys can be detected. The four pull-down resistors are
enabled / disabled together with an IOS instruction (PWn=2, b1). The pull-
down resistors cannot be controlled individually.
In backup mode, this port goes to the input desabled state, and the pull-down
resistors will be in the disabled state after a reset.
These output ports are used as the key source ports and can be set up to be
either unbalanced outputs or open-drain outputs. The output type is set with an
IOS instruction (PWn=2, b0, b2, b3). When used set to the unbalanced output
circuit type, diodes to prevent short circuits due to multiple key presses are not
required. If used set to the opendrain output circuit type, pull-up resistors
between VDD and the port pins are required.
In back up mode, this port goes to the output high-impedance state. After a
reset, this port will be in the output high-impedance state, and will remain in
that state until an output instruction (an OUT, SPB, or RPB instruction) is
executed.
* : Note that the output impedance requires care if these pins are used for any
purpose other than as key source ourputs.
