1 POWER ( OFF/ ON) switch
Press to turn power to the unit ON and OFF.
2 STANDBY/ON switch/indicator
This is the switch for electric power.
This switch does not function unless the POWER OFF/
ON switch is set to ON.
ON : When set to the ON position, power is supplied
and the unit becomes operational.
STANDBY : When set to the 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.
When the STANDBY indicator lights, the unit is in
STANDBY.
NOTE:
When performing timer recording with this unit, be sure to set
the POWER STANDBY/ON switch to ON.

5 INPUT SELECTOR knob/indicators
Turn the knob clockwise or counterclockwise so that the indica-
tor lights for your desired input source. Turning the knob clock-
wise causes the lit indicator to right. Turning counterclockwise
causes it to left.
CD : For compact disc playback with a CD player.
TUNER : For AM or FM broadcast reception with a tuner.
PHONO : For record playback with a turntable.
LINE/SB : Set to this position when listening to a program
from a component connected to the LINE/SUR-
ROUND BACK terminals.
TAPE 1/ : For playback with a cassette deck, CD recorder
or MD recorder connected to the TAPE 1/CD-R/
MD terminals.
6 TAPE 2 MONITOR button/indicator
Use when there is an adaptor component (graphic equalizer,
etc.) or cassette deck connected to the TAPE 2 MONITOR ter-
minals.
Off : Indicator goes out when not in use.
On : Indicator lights when using the adaptor component or
listening to the cassette deck.
NOTE:
When no connections are made to the TAPE 2 MONITOR termi-
nals, or when they are not in use, be sure to set this switch to the
off position. (No sound will be heard if it is set to the on position.)
