1) During FWD transport adjust Fand F' so that line A of 2-
LINE TAPE passes through the center of the head shield
plate (core center area)
2) During RVS transport adjust Rand R' so that line B of 2-
LINE TAPE passes through the center of the head shield
plate (core center area)
3) After the alignment above, reverse the transport direction
and check the FWD alignment again. If it is deviated, perform
alignment again.
(Tape used : SCC-1659,manufactured by A-BEX)
Adjust the azimuth for each L ch/R ch or FWD/RVS
becomes maximum.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list).
Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be
carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual
instruments or/and units.

CAUTION : For continued safety, replace
safety critical components only with
manufacturer's recommended parts (refer
to parts list).
Indicates safety critical components.
To reduce the risk of electric shock,
leakage-current or resistance
measurements shall be carried out
(exposed parts are acceptably insulated
from the supply circuit) before the
appliance is returned to the customer.
• DC voltages are as measured with a
high impedance voltmeter. Values may
vary slightly due to variations between
individual instruments or/and units.
