15. Damage requiring service — The unit should
be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been
damaged; or
B. Objects have fallen, or liquid has been spilled
into the unit; or
C. The unit has been exposed to rain; or
D. The unit does not appear to operate normally or
exhibits a marked change in performance; or
E. The unit has been dropped, or the enclosure
damaged.
16. Servicing — The user should not attempt to ser-
vice the unit beyond that described in the operating
instructions. All other servicing should be referred
to qualified service personnel.
17. Outdoor antenna grounding — If an outside
antenna is connected to the receiver, be sure the
antenna system is grounded so as to provide some
protection against voltage surges and built up
static charges. Section 810 of the National Elec-
trical Code, ANSI/ NFPA No. 70—1984, provides
information with respect to proper grounding of the
mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna-
discharge unit, connection to grounding elec-
trodes, and requirements for the grounding elec-
trode. See Figure.
®Use No. 10 AWG (5.3 mm?) copper, No. 8 AWG (8.4 mm?) alu-
minum, No. 17 AWG (1.0 mm?) copper-clad steel or bronze wire, or
larger, as a ground wire.
® Secure antenna lead-in and ground wires to house with stand-off in-
sulators spaced from 4 — 6 feet (1.22 — 1.83 m) apart.
© Mount antenna discharge unit as close as possible to where lead-in
enters house.
9Use jumper wire not smaller than No. 6 AWG (13.3 mm?) copper, or
the equivalent, when a separate antenna-grounding electrode is used

Tape recording
Recording level
The recording level is strongly related to sound quality,
distortion, S/N ratio, frequency response, etc. When it is
very high, S/N ratio is improved but distortion and fre-
quency response are degraded. When it is too low, the
opposite results. The best recording levels can be deter-
mined by referring to the PEAK LEVEL METER. It is easy
to record a disk or FM broadcast because their sound le-
vel is limited to a certain extent. However, it is difficult
to set the recording level when recording live sounds or

when recording from an open reel tape on which live
sound is recorded because the sound level varies within
a very wide range.
Notes:
1. The optimum recording level varies according to the sound source
and the type of tape. Find out the optimum recording level by re-
cording and playing several! times.
2. PEAK LEVEL METER readings during playback may differ
from those observed during recording. This is related to tape
sensitivity and is no problem.

How to make a blank section
To obtain the best performance from DPSS, blank sec-
tions are essential. Leave blank sections as follows:
1. Press REC/ARM key twice. A blank sections of about
4 seconds is made and the unit enters the rec pause
mode. During recording from the turntable player, the
unit may not automatically enter auto rec mute mode.
At this time, press the REC/ARM key, then press the
same key again slowly.
2. To make a blank section of more than 4 seconds,
keep the REC/ARM key pressed the second time. A
blank section equals to the time the key is kept
pressed is made. When the REC/ARM key is re-
leased, the unit enters the rec pause mode.
3. To make a blank section of less than 4 seconds,
press the REC/ARM key twice and press the REC/
ARM key again within 4 seconds. The unit enters the
recording mode. When the pause key (as) is pressed
after the REC/ARM key has been pressed twice, the
unit enters the rec pause mode.

Quick re-recording
If you accidentally include unwanted material while you
are recording an FM broadcast, etc., you can go back to
the beginning of that section of tape to start over again
by using the following procedure.
A blanc section of more than 4 seconds is necessary before
the beginning of the tape recording.
1. When the tape is moving in the forward direction,
press the rewind key (<<). The recording stops, the
tape is rewound to the beginning of the recording, a
blank section of about 2 seconds is left and the tape
stops.
2. When the tape moves in the reverse direction, press
the fast forward key (®). The recording stops, tape
is rewound to the beginning of the recording, a blank
section of about 2 seconds is left and the tape stops.
3. To resume recording, make a 4-second blank section
by pressing the REC/ARM key twice, then press the
same key again.
Note:
if you use this function at the beginning of the recording, this
will not often operate normally.

High-speed dubbing
To make the dubbing speed increased, press the high-
speed dubbing key (HIGH ® ).
Notes:
1. Dubbing is not possible unless both A and B decks are in the
stop mode.
2. During dubbing, it is not possible to adjust the recording level.

the
tape

3. During dubbing, regardless of ON/OFF of Dolby NR switch,
you
cannot
change

switch.
(The
same
tape
as
the
one
in
A deck is made.)
e.g. When the tape in A deck is recorded with Dolby B, the tape
in B deck will be recorded with Dolby B.
4. Dubbing from the dubbed tape degrades the sound quality. It is
therefore recommended to load the original tape in A deck.
5. TV noise may be recorded during high-speed dubbing if TV is
near the system, In this case, keep TV away from the system.

Timer stand by operation
By using the built-in TIMER STAND BY mechanism in combina-
tion with an audio timer (available from many dealers), the
deck begins to record or play at any desired time.
Unattended recording
1. Connect the power cords to the components and set the
timer so that power is supplied to each component. (Timer
setting procedures vary with the type of timer used. Fol-
low the instructions of the timer’s manual.)
2. Turn on the power switches of the components to be
used for recording.
Tune on the station desired and set the record level.
4. Set the volume control of the amplifier to its minimum
setting.
5. Set the timer to the required time referring to the timer’s
instruction manual so that the power will be switched ON
at the preset time.
6. Load a tape for recording into deck B or deck A.
The relay recording from deck B to deck A can be also
setting the DIRECTION switch to norma|l mode
( = ) or reverse mode { > ) position.
7. Set the DUBBING speed key to NOR. (2) (Normal).
8. Set the DOLBY NR switch to ON if the recording is to be
made using the noise reduction system.
9. Set the TIMER switch to REC.
10. Power to the components will be switched ON at the
preset time and recording will start.
11. Recording stops when the tape end is reached.

Note:—2
To ensure that the automatic shut off switch operates before the
power is shut off, set the timer so that it operates for a little longer
than the playing time of the tape.
Timer-controlled playback
1. Connect the timer as described for “Unattended record-
ing”.
2. Set the timer so that power is supplied to each compo-
nents.
3. Turn on the power switches of the components used for
playback.
Load a recorded tape and set each switch referring to
“Tape playback”.
