Setting Aside Main PCB Page 1 of 3
Application This procedure is for temporarily moving the Main PCB (LIFEPAK 500
Monophasic AED or LIFEPAK 500 Biphasic AED) out of the way to provide
access to other components. In these cases, it is necessary to disconnect the
speaker leads (P9), and on the Biphasic AED, it is necessary to disconnect the
flex cable (P11). If you are installing a new Main PCB, perform Replacing Main
PCB—Monophasic AED or Replacing Main PCB—Biphasic AED instead.
Preparation Before moving the Main PCB, you must first follow the procedures:
■ Removing Top Cover
WARNING!
Shock hazard. The Energy Storage Capacitor carries high voltage.
Remove the battery and discharge the capacitor before handling. See:
■ Discharging Energy Storage Capacitor
To move the Main PCB:
1. Place the AED on the work surface with the handle facing forward.
2. Disconnect P9 of the speaker cable from J9 on the right underside of the
Main PCB. (LIFEPAK 500 Biphasic AED only): disconnect P11 from J11.
3. Carefully lift the Main PCB off of the four PCB mounts and tilt the board
toward the left, exposing the underside of the Main PCB.
