LIFEPAK 9 defibrillator/monitor
Warning SHOCK HAZARD. Terminals and wires carrying high voltages up to | )
+11.6kV are exposed with the defibrillator/monitor cases removed. Do not
touch internal circuitry except as indicated in these procedures.
Warning SHOCK HAZARD. When charged and discharged during this TCP, the
LIFEPAK 9 defibrillator/monitor discharges up to 360J of electrical energy
through the defibrillator paddles. Unless discharged properly as described
in this TCP, this electrical energy may cause injury or death. Do not
attempt to perform this procedure unless you are thoroughly familiar with
the operation of the LIFEPAK 9 defibrillator/monitor.
Warning POSSIBLE ARCING AND PADDLE DAMAGE. When discharging the
defibrillator into the internal test load, make sure the standard paddles are
securely and properly stored in the paddle storage area (STERNUM paddle
on the left, APEX paddle on the right). This helps prevent arcing and
formation of pits on paddle electrode surfaces. Pitted or damaged paddle
electrode surfaces can cause patient skin burns during defibrillation.
Caution Possible Component Damage. Static Sensitive Devices (SSDs) require
special handling. Follow the special handling procedures described on
page 4—5 to prevent static discharge and damage. Refer to Table 5-1 to
identify PCB assemblies containing SSDs.
TCP-Voltage Checks 1. With the defibrillator/monitor power off, remove the front panel to
access the test connector J3 on the Power Conversion PCB (leave the
front panel connector cable connected). For disassembly instructions,
refer to page 4-7, Front Panel Removal.
2. Connect the ground lead of the DMM to pin 7 of J3. Refer to
Figure 3-8.
3. Turn the defibrillator/monitor power on and check that the voltages are
within the limits listed in Table 3-6.
