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.

(up position; see the image on the right). If no device or an unterminated device was connected to the loop feed

in step 5, set the switch to 75Ohm (down position).

Step 7

Connect up to ve display composite video devices to the outputs (7), using composite video connectors.
