Touch [START]. The confirmation display appears.
5. Touch [OK].
When the system check is complete, "SPEAKER SELECT"
screen appears.Select the apeaker system. After this ope-
ration, the diaplay returns to the original mode.
CODEMATIC
This function prevents persons who do not know the touch
sequence from easily operating this unit. The Touch Code
display appears when DCP is attached and the power is
turned ON with "CODEMATIC" set to "ON".
If you touch the display in this screen in the preset order,
"SUCCESSFUL" is displayed and the power is turned OFF.
When the power is next turned ON, the Touch Code display
does not appear, and the main display in the radio mode or
CD mode is displayed.
9-1. Laser diode
The laser diode terminals are shorted for transporta-
tion in order to prevent electrostatic damage. After
replacement, open the shorted circuit. When remov-
ing the pickup from the mechanism, short the termi-
nals by soldering them to prevent this damage.
9-2. Actuator
The actuator has a powerful magnetic circuit. If a
magnetic material is put close to it. Its characteris-
tics will change. Ensure that no foreign substances
enter through the ventilation slots in the cover.
9-3. Cleaning the lens
Dust on the optical lens affects performance. To
clean the lens, apply a small amount of isopropyl
alcohol to lens paper and wipe the lens gently.
9. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by
electrostatic charge caused by your clothes and body. Make
sure to avoid electrostatic charges on your clothes or body,
or discharge static electricity before handling the optical
pickup.
