connector (2). When power is applied to the unit, the front panel LED (1) lights green.
CAUTION:
• Power supply voltage polarity is critical.Identify the power cord negative lead by the
ridges on the side of the cord (see the figure on the right).
• La polarité de la source d’alimentation est primordiale. Repérez le pôle négatif du
cordon d’alimentation grâce aux stries sur le côté du cordon (voir la figure à droite).
• Always use a power supply supplied by or specified by Extron for this unit. Use of an
unauthorized power supply voids all regulatory compliance certification and may cause
damage to the power supply and the distribution amplifier.
• Utilisez toujours une source d’alimentation fournie ou spécifiée par Extron. L’utilisation
d’une source d’alimentation non autorisée annule toute certification de conformité
réglementaire et peut endommager alimentation et l’amplificateur de distribution.
• If not provided with a power supply, this product is intended for use with a UL Listed
power source marked “Class 2” or “LPS” rated 12 VDC, 0.5 A minimum.
• Si le produit n’est pas fourni avec une source d’alimentation, il doit être utilisé avec une
source d’alimentation certifiée UL de classe 2 ou LPS avec une tension nominale de
12Vcc, 0.5 A minimum.
Step 4
Connect a video source to the video input (3), using composite video (BNC) connectors.
