Connect inputs and outputs

Always switch OFF the power on each device before connecting it to your 691/692. For best results, we recommend that you always use Kramer high- performance cables to connect AV equipment to the 691/692.

For optimal performance, use the RECOMMENDED Kramer cables available at www.kramerav.com/product/691.
Using third-party cables may cause damage!

To install/replace the OSP-MM1 or other Kramer recommended SFP+ transceiver:

Pull the bail out and remove the currently installed transceiver, insert the protective cap and store in a safe place.
Make sure the bail of the new transceiver is pushed up, in the closed position.
Insert the new transceiver into the relevant optical device SFP+ slot and push it in until it clicks.
Remove the protective cap and store it in a safe place for future use

Warning: Connecting the OSP SFP+ connector to an LC(APC) fiber connector may cause poor performance and damage the connector!
Refer to www.kramerav.com/downloads/691 for more information.

Invisible laser radiation present.
Avoid long-term viewing of laser.
Avoid the use of magnifying viewing aids or instruments (such as binoculars, telescopes, microscopes and magnifying lenses, but not spectacles or contact lenses).
Avoid placing optical devices in the emitted beam that could cause the concentration of the laser radiation to be increased.
