WIRED REMOTE CONTROL BOX CIRCUIT DIAGRAM
1. Circuit Diagram
Second and Subsequent Units
•
Make a control box using the supplied remote control box connection wire.
•
Do not connect the left channel of the plug (Vcc) with 8001 (200 ohms) in the second
and subsequent units.
•
Use resistors having a tolerance of within ±5% (1/4W). 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-790R 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 incorrect 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 and FF,
or PLAY and REW buttons at the same time.
6.
Pressing a button of the wired remote control box and a button of the
main unit, DN-790R, (for combined operations) is not possible.
7.
Do not switch the power on or off when the cable of the wired remote
control is connected. Doing so will cause incorrect operation.
