plied to VIDEO IN connectors 1 to 4.
e
Audio input connector (AUDIO IN)
RCA audio cable is connected to this connector.
r
Audio output connector (AUDIO OUT)
This connector (RCA pin jack) supplies audio output
signal. Connect the cables to a speaker equipped with

t
Connector terminal
These are the connectors for alarm input, alarm output,
AUX (auxiliary control) output, and time adjust input.
When connecting an external device, first remove
approx. 9 mm - 10 mm of the outer jacket of the cable
and twist the cable core to prevent a short circuit.
• Specification of cable
(wire): AWG #22 - #28,
Single core, twisted
Important:
• Do not connect 2 or more wires directly to a terminal.
When it is necessary to connect 2 or more wires, use a
splitter.
