Clear-Com HX System Frames - Manual (Page 30)

Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type.
Lithium batteries can overheat or explode if they are shorted. When handling
the CPU card or a loose battery, do not touch any external electrical
conductors to the battery’s terminals or circuits to which the terminals are
connected.
Note:
When servicing the battery, make sure that the jumper on CON9 is connecting pin 2
(common) to either pin 1 (on) or to pin 2 (off). If the common is left floating, the CPU may
behave unpredictably. For example, the microprocessor may reset itself intermittently.

2. Install the Eclipse HX-Delta to the standard 19 inch rack.
Environmental note:
Leave clearance on all sides of the matrix chassis to ensure proper airflow. Do not
block ventilation vents.
