CLEANING
Use of the AKAI Cleaning Kit CK-300 (separately sold) is
recommended.

high-tone range Clean Recording Head, Play-
Drop-out —---------—- _ back Head and Capstan.
No recording ability —
Incomplete erasing . Clean Erasing Head.
Unstable tape travel .... Clean Pinch Roller, Capstan,
Tension Arm and Tape Guide.
CLEANING METHOD ‘Fig. a. bi
Clean as shown in figures using a cotton swab stick
immersed in cleaning solution.
@ For Pinch Roller, cleaning will be easier when using a
cloth immersed with cleaning solution.
@ For Pinch Roller. use a cleaning solution that will not
adversely affect the rubber material.
DEMAGNETIZING
Use of AKAI Head Demagnetizer, AH-9-J, is recommended.
©@ Tone deterioration in
high tone range Demagnetize Recording Head
© Noise and Play back Head.
@ When demagnetizing heads, also demagnetize such parts
as Capstan, Tension Arm and Tape Guide.
DEMAGNETIZING METHOD (Fig. c)
Prior to demagnetizing parts. do not forget to disconnect
power of the entire unit.
Carry out Operations ! through 4 described below for
each head.
1, Connect power of Demagnetizer to a place at least
30cm away from the head.
2. Bring the tip of the Demagnetizer close to the gap of
the head and make circular motions.
3. With the power of the Demagnetizer still on, draw
Demagnetizer gradually away from head moving it in
circles.
4. After the Demagnetizer has been brought at least 30cm
away from the head, turn off power.

VOLTAGE AND CYCLE CONVERSION
? Kindly refer this Voltage and Cycie Conversion to a qualified
Service Repair Shop or professional service personnel.
To service personnel:
VOLTAGE 7
The machine is equipped with a universal voitage selector offering a
selection of voltage from 110V to 240V AC.
Voltage is preset at the factory according to destination. However, if
necessary, readjustment can be made as tollows:
(1) DISCONNECT POWER CORD and remove rear panel.
{2} Remove the Voltage Selector Plug and reinsert so that proper
area voltage shows through the plug cut-out.
(3) Change fuse to correspond with voltage (Refer to fuse tag
instructions for proper fuse).
. To maintain optimum performance and prolong the life of
your machine, it is important that the line voltage be held
within 10% of standard area voltage.
CYCLE
* As the unit is equipped with C.P.G. AC Servo Motor. cycle
change for capstan drive motor is not necessary. Following
instruction ts just for readjusting reel motors torques according
to cycles,
<1) DISCONNECT POWER CORD.
12) Remove rear panel.
(3) Cycle Change Switch is located on the Sysiem Control P.C.
Board. Set to 50 Hz or 60 Hz pasition according to area power
source.
