TCP-Setup
Take the rear cover off the adapter (see Section 4). Lay the adapter flat
in front of the LIFEPAK 9 defibrillator/monitor with the paddles
removed from the paddle well. Pull out the High Voltage Connector
Cable from the adapter and connect it to the paddles connector on the
LIFEPAK 9 defibrillator/monitor.
TCP-Power Supply and No calibration is needed for the Power Supply and Oscillator checks in
Oscillator Checks Table 3-3. Use the lead of VSP1 which is closest to TP3 for nonisolated
ground; use the lead of VSP1 closest to TP6 for isolated ground.
