CIRCUIT DESCRIPTION
Function Description
Display select key. Available only when in the-radio mode.
When this key is pressed, the display is changed from the clock display to frequency or vice versa. However, five seconds after
the key is pressed, the display is restored to the priority mode (depending on the diode matrix PRIORITY).
When the clock is not provided (CLKSEL=0), this key has no effect.
a) ON: Priority is provided
b) OFF: No priority
(1) NR key (RADIO/TAPE common key)
(2) WIDE-ADV key (Independent RADIO/TAPE key)
(1) NR key:
BAND A: "0", 1"
NR SEL: 1"
With the above status, this key is used as the NR select key.
Each time the key is pressed, the BAND2/NR output pin and "'NR" display on the LCD panel are inverted. When "NR" is
displayed on the LCD panel, the BAND2/NR pin outputs the high level, and when the display is not lit, low level is output.
(By initialization when the power is turned on, it outputs low level.)
(2) WIDE-ADV key:
BAND A: "0", "1°"
NR SEL: "1"
With the above status, this key is used as the WIDE-ADV select key.
In the Radio mode:
Used as the WIDE select key.

Each time the key is pressed, the BAND2/ADV output pin and the "WIDE" display on the LCD panel are inverted. When the
"WIDE" is displayed on the LCD panel, the BAND2/ADV pin outputs the high level, and when the display is not lit, low level is
Output.
On Tape mode:
Used as the ADV select key.
Each time the key is pressed, the BAND2/NR output pin and the "ADV" display on the LCD panel are inverted. When the
"ADV" is displayed on the LCD panel, the BAND2/NR pin outputs the high level. When the display is not lit, the low level is
output.
{By initialization when the power is turned on, low level is output.)
Note:
When the following status is selected in the diode matrix, the NR key and the WIDE-ADV key are not effective.
NR SEL: "0"
BAND A: "0"
BAND B: "1"
setting is followed to the diode.
