IMPORTANT:
Be sure to use the power cable plug (accessory) provided with this product.
Be sure to fully insert the power cable plug (accessory) into the power supply terminal (12 V
DC). Otherwise, it may damage the camera or cause malfunction.
When installing the camera, make sure that excessive force is not applied to the power cable.
Be sure to use an AC adaptor compliant with the Specifications (written in the indication label
on the bottom side of this unit) regarding power source and power consumption.
IMPORTANT:
Connect/disconnect the audio cables and turn on the power of the camera after turning off
the power of the audio output devices. Otherwise, loud noise may be heard from the speaker.
Make sure that the stereo mini plug is connected to this cable. When a monaural mini plug is
connected, audio may not be heard.
When connecting a monaural speaker with amplifier, use a locally procured conversion cable
(mono-stereo).
