Important:
• Connect/disconnecttheaudiocablesandturnonthe
power of the camera after turning off the power of the
audio output devices. Otherwise, loud noise may be
heard from the speaker.
• Audio output cable
Connect a stereo mini plug (ø3.5 mm). (Audio output
is monaural.) Use an external speaker with amplifier.
• Recommendedcablelength:10m{32.8feet} or less
Note:
• Makesurethatthestereominiplugisconnectedto
this cable. When a monaural mini plug is connected,
audio may not be heard.
When connecting a monaural speaker with amplifier,
use an optional conversion cable (mono-stereo).
