SECTION 1: Introduction
Description
The Responder 2000 is a defibrillator/monitor/pacemaker intended for use by personnel trained in its operation. The
device is lightweight, portable, easy to use and reliable. It incorporates a 320 x 240 transmissive color TFT color display
for wide viewing angles in all light conditions. The device operates using either an AC power supply or internal
rechargeable Li-Ion battery. The device provides continuous ECG monitoring and three types of therapies: defibrillation,
cardioversion and external pacing. Defibrillation can be applied manually or semi-automatically. Pacing therapy can be
either fixed or demand. The device employs patented RHYTHMx
Biphasic waveform delivers impedance-compensated energy ranging from 2-270 Joules. Features and options include
external paddles, spoons, disposable pads, 3- and 5-lead ECG, pulse oximetry (SpO2), built-in 60 mm thermal printer,
internal storage of event history and remote synchronization to bedside monitor.

2. Press the calibration button on the battery. The Mode light turns red to indicate calibration in progress.
To stop calibration, press the calibration button again. The Mode light turns green and the battery begins to
charge.
To calibrate the battery without the external charger:
1. Insert the battery into the Responder 2000.
2. Plug the Responder 2000 into an AC outlet.
3. Allow the battery to fully charge.
4. Disconnect the AC power cord and leave on the Responder 2000 until the battery is fully discharged (full
discharge takes about four hours).
5. Reconnect the AC power cord and allow the battery to fully charge.

equipment, read and follow all safety precautions and instructions in the Operator’s Manual.
WARNING: Shock Hazard or Equipment Damage
Before servicing the Responder 2000, disconnect the AC power cord and remove the battery.
WARNING: Shock Hazard or Equipment Damage
Internal components of the Responder 2000 may still contain high voltages even after the AC power cord and battery are
removed. Before working on any internal component, verify high voltages are not present.
WARNING: Shock Hazard or Equipment Damage
Some service activities require the Responder 2000 to be energized with covers removed. Ensure all personnel and
equipment is clear while the equipment is energized.
WARNING: Biological Contamination
During normal operation, the Responder 2000 may be contaminated by blood, body fluids, or other biological agents.
Always assume the Responder 2000 is contaminated and use appropriate safety procedures until decontamination is
performed. Always decontaminate the Responder 2000 in accordance with hospital or facility procedures before servicing
or returning to service. Refer to the Responder 2000 Operator's Manual for recommended cleaning agents and
instructions
Caution: Electrostatic Damage
Always use a wrist grounding strap and anti-static mat while performing service on any internal components.
Caution: Voiding Product Warranty

Disassembly Overview
WARNING: Lethal Shock Hazard.
In the event of equipment failure, the two main capacitors may retain dangerous voltages even if the Responder
2000 is disconnected from AC power and the battery is removed. Normally, the capacitors are discharged when
power is shut off; however, it is possible for equipment damage to prevent the capacitors from discharging
properly.
Always assume the capacitors are fully charged.
Caution: Shock Hazard or Equipment Damage.
Before opening the case, ensure the AC power cord is disconnected and the battery is removed.
Caution: Equipment Damage.
Always wear a grounding wrist strap and use an anti-static mat when handling parts.
Caution: Procedure Failure.
Even though some assembly steps may not be applicable to a specific replacement procedure, all other steps
must be performed in the order listed.
The Responder 2000 has two access points:
Rear Cover: Provides access to Capacitors, Therapy Board, optional SPO2 Board, and ECG Board, and Front Bezel.
Removing the Bezel allows access to the Main Board, Printer, and Display.
Base Cover: Provides access to the Power Supply, Power Control Board, Fan, and Switches.
Note: The Speaker is part of the Front Body Assembly.
