Line Voltage Selection
Line Voltage can be changed by the following modification:
1. Disconnect the AC power cord.
2. Remove the cover.
3. Change the position of the jumper-lines @follows.
jumper—line @position
NOTE: When replacing a PCB which has the primary winding
circuit of Power-transformer, be sure to compare its
circuit with the diagram in Service Manual.
jumper-lines on the PCB may have to be removed.
Forgetting this check-up will cause a serious damage.
4. Stick 2 line voltage label on the rear panel.

NOTES:
@ Parts marked by “NSP” are generally unavailable because they are not in our Master Spare Parts List.
© The A\ mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to
use parts of identical designation.
@ Parts marked by “ @” are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.

When
ordering
resistors,
first
convert
resistance

as
shown
in
the
following
examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J = 5%, and K
10%).

@ POWER (STANDBY/ON) switch/indicator
This is the switch for electric power.
ON ai iceecestiicecs When set to ON position, power is supplied and
the unit becomes operational.
STANDBY ....... When set to STANDBY position, the main power
flow is cut and the unit is no longer fully
operational. A minute flow of power feeds the
unit to maintain operation readiness.
During standby,the STANDBY indicator lights up.
NOTE:
@ The memory will be backed up so long as the power cord is
unplugged.
@ !f the power cord is unplugged, the memory will be retained
for several days.
@ When not using the unit for a long period, disconnect the power
cord.
@ CHARACTER button
Press this button, "“CHARACTER?’ is displayed, and the mode
switches to manual station name input.
@ PTY SEARCH button
Press this button, "SEARCH" is displayed, and the mode switches
to program type search.
@ EON PTY/TA button/indicator
If receiving a station broadcasting EON information, the radio can
automatically keep track of broadcast information from other
network stations. The EON indicator lights up when (TA) or (PTY)
is specified.
If you specify traffic information (TA) or program type (PTY)
beforehand, the frequency will change automatically when the
specified program begins.
The indicator of the display section lights up when EON
information is received.
The TA/PTY characters of the display section and EON indicator
blink when the specified (TA) or (PTY) broadcast is received.

TUNING knob
Use for tuning. To raise the frequency, turn in a clockwise
direction; to lower the frequency, turn counterclockwise.
AM: Frequency changes in 9kHz steps.
FM: Frequency changes in 50 kHz steps when FINE TUNING is
off, and 25 kHz steps when FINE TUNING is on.
In the Station Name input mode, and PTY Search mode and EON
PTY MODE, use to select characters and program type.
@ MEMORY button
Use to preset stations.
This is also used for FM or AM broadcast manual station name
character selection.
@ ANT A/B button
Selects between two antennas connected to the FM antenna A
and B terminals. (ANT- [AJ] or (ANT- [B]) indicator lights up.
NOTE:
This button’s status is preset for each station in station memory.
@ RF ATT button
Set this button to on when receiving strong FM signals (nearby
stations) to reduce sound distortion (RF ATT indicator lights).
Normally, this button should be set to off.
This button does not affect AM reception.
NOTE:
This button’s status is preset for each station in station memory.
@ IF BAND button
Each time this button is pressed, the bandwidth of the IF circuit
switches between “normal” and “narrow” for the FM band.
Set to NARROW in case of interference from other stations.
The NARROW indicator lights up. When not lit, normal filter
bandwidth is selected.
This button does not affect AM reception.
NOTE:
This button’s status is preset for each station in station memory.
(3 MPX (multiplex) MODE button
id AUTO —> MONO 1
This button does not affect AM reception.
AUTO:
“ AUTO " is not displayed.
Normaily leave in this mode for reception. When a stereo FM
broadcast is received, it will be automatically reproduced in stereo
sound and the STEREO indicator lights up.
NOTE:
When the signal level is too weak for reception, sound output is
automatically muted.
MONO:
MONDO indicator lights up.
To receive stereo broadcasts in monaural.
If there is too much noise during stereo reception of a weak signal,
you can reduce the level of noise by switching to MONO.
NOTE:
This button’s status is preset for each station in station memory.
@ STATION CALL buttons
Use these buttons to preset stations and to receive the already
preset stations.
These are also used when performing direct access tuning.
@® CLASS button
Use to switch between preset memory classes 1 to 4. In each
class, 10 stations can be memorized using the STATION CALL
buttons, enabling a total of 40 stations to be memorized.
DIRECT button
When this button is pressed, the STATION CALL buttons function
as ten-key number buttons for direct input of the desired reception
frequency. Press again to cancel this mode.
@ MEMORY SCAN button
This button is used for station memory scan.
Press to receive currently selected class and preset stations for
a few seconds in sequence. Press again, and reception of the
station presently begin received will continue.
