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 at the front of the manual.
The following guidelines apply whenever you set up the receiver for operation:
•
When disconnecting a LEMO cable, grasp the cable by the sliding collar or
lanyard and then pull the cable connector straight out of the port. Do not twist
the connector or pull on the cable itself.
•
To securely connect a TNC cable or antenna, align the cable connector with the
receiver receptacle and then thread the cable connector clockwise onto the
receptacle until it is snug.
•
To insert the internal battery, place the battery in the battery compartment,
ensuring that the contact points are in the correct position to align with the
contacts in the receiver. Slide the battery into the receiver until the battery
compartment latches are locked into position.
