WARNING – These receivers use a rechargeable Lithium-ion battery. To avoid personal
injury or equipment damage, make sure that you read and understand the Safety
Information on page iii at the front of this manual.
The following guidelines apply whenever you set up your receiver for operation:
• When plugging in a Lemo cable, make sure that the red dots on the receiver port
and the cable connector line up. Do not use force to plug cables in, as this may
damage the connector pins.
• When disconnecting a Lemo cable, grasp the cable by the sliding collar or
lanyard and pull the cable connector straight out of the port. Do not twist the
connector or pull on the cable itself.
