C-MOS lC handling precaution

The CrMOS lC's construction makes this part susceptible to damage
bV static electrlcitv and so take sufficient care in regard to follow-

ing articles.

1. Need to be put on conductive sheet, to be put in a metallic box
and to be wrapped by aluminium toll for transportation and

deposit.

2, To use solder iron less than 40W (less than 260' C) of power
consumption for soldering, But do not overheat more than 10

second.

3. Do not perform a conductlvnv test With a tester, etc Reler to

the circuit voltages oi each part.

4 The ICs on the electrical parts which are indicated by an C-

MOS IC symbol mark ( (4,) l.

Circuit description

1. Outline
This is a controller with the phono-syncrate function added to
the mechalogic controller (with single capstan, CUE/REV

functions) used in the deck. The program size is 1k byte.

3. Masha-controller specifications

3-1. General specifications

3-1-1. It is same as the general controller for STOP, PLAY, REW,
FF, REC, REC/PLAY, PLAY PAUSE, REC/PLAY-PAUSE

3-12. CUE, REV:
This is possible by double-pressing the PLAY key and FF (or
REW) key. Changing from CUE mode to REV mode, or from
FlEV mode to CUE mode is possible without entering the
STOP mode; by nipple-pressing keys.

3-1-3. ONE-REC:
By pressing only the REC key in the PAUSE mode, the
unit enters the REC/PLAY-PAUSE mode.

34.4. TlMER/REC/PLAY:
Same as specified in the general specifications

3-1-5. TIMER-PLAY:
Same as specified in the general specifications

3-1-6. AUTO»REPEAT:
Same as specified in the general specifications

3-1-7. MEMORY-STOP:
Same as specified in the general specifications

3-1-8. MEMORY-PLAY:

Same as specified in the general specifications

3-1-5. MS (music sensor):
By entering the CUE or REV mode with the MS switch
set to ON, only the STOP key input signal or MS signal
is accepted.

3-2. Additional functions

3-2-1. REC-MUTE-TIMER (1):
When the REC-MUTE key is pressed and released for use
of M3. the unit enters the REC/PLAY-PAUSE mode after
4 sec. When the key 15 pressed again, REC/PLAY mode
continues.

3-2-2. RECMUTErTIMER (2):
Hold the key depressed for 4 sec or more to set the unit in
the nosignal mode for 4 sec or more. After 4 sec, the LED
flashes every second, and when the key is released the unit
enters the REC/PLAY mode.

3-23. PHONESVNC:

When the PHONO switch is set to ON and the arm lifts in
the REC/PLAY mode, the unit enters the REC/PLAY-
PAUSE mode, and when the PHONO switch is set to ON
and the arm lowers in the REC/PLAY-FAUSE mode, the
unit enters the REC/PLAY mode.
