Key Operation
NR
1
(NOISE REDUCTION) and NR
2
control key.
This key is valid in the tape mode.
Its operations depends on the setting of the initialize diode ENNR2 switch as shown below.
Each time this key is pressed, the LCD panel “NR
1
” display and the NR
1
pin (pin 22) output
are inverted.
High level is output from the NR
1
pin while “NR
1
” is displayed.
When the power is turned on, the OFF state is set (“NR
1
” display OFF, NR
1
pin Low level).
Each time this key is pressed, the display and output are switched as shown below.

AMS (AUTO MUSIC SEARCH) control key.
This key is valid in the tape mode.
Each time this key is pressed, the LCD panel “AMS” display and the AMS pin (pin 20) output
are inverted. High level is output from the AMS pin while “AMS” is displayed.
When the AMS pin is High level (AMS mode), if the TPSET switch is ON, the AMS pin holds
the High level output even if the mode is switched to the CD or radio mode.
When the power is turned on, AMS is turned off (“AMS” display OFF, AMS pin Low level).
Radio monitor key.
This key is valid in the tape and CD modes.
Each time this key is pressed, the radio monitor mode is inverted. In the radio monitor mode,
the LCD panel “RDMONI” display lights.
In the radio monitor mode, all band tuning operations are possible and radio muting (RDMUTE
pin) is turned off and audio muting (AMUTE pin) is turned on.
