Press this button to select either

Deck A or Deck B to be controlled.

• Do not connect the left channel of the plug (Vcc) with R001 (200 Ω/ohms) in the second and subsequent units.

• Use resistors having a tolerance of with ±5%.

Use of resistors having a poorer tolerance will cause incorrect operation.

• Never short circuit the left-channel line (Vcc). Doing so will damage the main unit.

2. Operation with Parallel Connections

A number of DN-780R units can be simultaneously operated in parallel with 1 button.

Operation with parallel connections can be used with a maximum of 5 units.

Connection of 6 or more units will lead to indicator operation.

3. Cable Length

The longer the length of the cable, the more susceptible the system will be to the effects of external noise.

Keep cable lengths to 2 m or less.

Do not locate equipment that produces electrical noise in the vicinity of the cable.

Doing so might lead to incorrect operation due to the noise.

4. Do not disconnect or connect the remote control plug during operation of the unit.

The pins of the plug might cause a short circuit of the pins inside the jack which can stop the operation.

5. Pressing more than one button of the wired remote control box at the same time (for combined operations)

is not possible.

A music search operation will not result from pressing the Play (1) and Fast Forward (7), or Play (0) and

Rewind (6) buttons at the same time.

6. Pressing a button of the wired remote control box and a button of the main unit, DN-780R, (for combined

operations) is not possible.

Note on Connecting the Remote Control Box

When multiple sets are connected to a single remote control box, the other sets may operate erroneously

when this set’s power is turned on off or when the cord is connected or disconnected from the remote control

jack.

Turn off the remote control box’ toggle switched (SW101, 102, ...) when turning this set’s power on or off or

when connecting or disconnecting the cord from the remote control jack while other sets are connected to the

remote control box.

#2 RC IN control Jack
