Safety Conventions
The manual uses the following conventions for Notes, Cautions, and Warnings.
Note —A Note calls attention to an important point in the text.
Caution A Caution calls attention to a condition or possible situation that could damage or
destroy the product or the user’s work.
Warning A Warning calls attention to a condition or possible situation that could cause injury
to the user and/or patient.
Safety Requirements
Note —The safety indications in this chapter apply to general monitor use. Safety
indications in other chapters apply to specific monitor measurements.
Follow the instructions in this user manual when using the monitor. However,
conventional medical practices always supersede this document. Significance of safety
requirements set forth here in this manual is not in order of reading sequence.
Warning The monitor is not for home use.
The monitor is only for use on one patient at a time. The monitor is not for
diagnostic or therapeutic use.
The monitor is not an apnea monitor. The respiration measurement does not
recognize obstructive and mixed apneas —it only indicates when a user-defined
time has elapsed since the last detected breath.
Anyone who connects to additional equipment to the signal input port or signal
output port configures a medical system and is therefore responsible to ensure that
the system complies with the requirements of standard IEC 60601-1. Never
permanently install equipment connected to the signal input or output ports. If in
doubt, contact MEDHealth Supplies.
To avoid mixture, clear all historical data of the last patient before monitoring a
new patient. Ensure that the patient monitor is in good working condition and is
placed in proper position before clinical use.
Never rely exclusively on the alarm system for patient monitoring. You must
periodically check that monitor alarms are working properly. The most reliable
method of patient monitoring combines close, personal surveillance along with the
correct operation of the monitor.
For pacemaker patients, rate meters may continue to count the pacemaker rate
during occurrences of cardiac arrest or come arrhythmia. Do not rely entirely upon

ZD120E User Instruction Manual
Fourth Edition: October 2021
Version: V1.4
VI
rate meter alarms. Keep pacemaker patients under close surveillance. See this
manual for disclosure of the pacemaker pulse rejection capability of this instrument.
Never use the monitor during MRIs or CT scans.
Never use cables with exposed conductors. Only use undamaged cables and
connectors to avoid personal injury.
Never simultaneously touch the patient and the input or output terminal of the
monitor.
The monitor can be used with electrosurgical devices. To avoid burns or death,
ensure that the electrosurgical circuitry is properly connected.
Ensure that the patient is not connected to any metal, the surface of any conductors,
or grounded parts of any devices when a defibrillator is in use. Never touch the
patient, table, or instruments during defibrillation.
Never use the monitor in an environment of anesthetic gases.
Disconnect the AC power supply and remove the battery before disassembling the
monitor.
Caution To avoid personal injury, only use accessories and parts produced or recommended
by the manufacturer. Otherwise, damage to the monitor can occur.
Position power cords and other cables to prevent tangling, patient contact, or
electrical interference.
Always use a three-wire receptacle in order to properly ground the monitor. Use the
monitor on battery power only if you suspect any problem with external grounding
or wiring.
Only connect the monitor to a power outlet with correct protective grounding. If no
grounded power is available, only use the monitor with internal batteries.
The battery will discharge over time when stored inside a monitor with no AC
power. Keep the monitor plugged in when storing it and perform a monthly check
of battery power.
If multiple devices are connected to a patient, the sum of the leakage currents may
cause a dangerous situation. Therefore, qualified service representatives should
always perform current leakage tests before setting up the connections. This
ensures that leakage is within limits and prevents personal injury and
environmental damage. If any question remains, consult the manufacturer for
correct usage.
The monitor must conform to the international standard IEC 60601-1-2 and other
applicable EMC standards. Interference takes place when electromagnetic energy is
extremely high. Ensure that any nearby instruments are also in compliance with
EMC standards. Never turn on or use portable communication devices like mobile
phones or portable dual-channel radios near a monitor.
Unknown electromagnetic interference could be caused by radio transmitters or
nearby televisions. Move patient monitors away from these devices or insert
shielding materials around the monitor.
Any devices connected to the monitor must comply with the IEC standard for that
device. For example, data processing devices must comply with IEC 60950 and
medical devices must conform to IEC 60601-1. The whole system must comply with
the most recent IEC 60601-1-1 standards.
To ensure monitor safety, all service parts and accessories must comply with IEC
60601 standards. The system configuration of the monitor must comply with IEC

ZD120D/ ZD120E User Instruction Manual
Fourth Edition: October 2021
Version: V1.4
VII
60601-1-1 medical electrical standards.
If patient data is lost, closely monitor the patient, or replace the monitor
immediately until the monitor restores normal function again.
Monitoring will be stopped while user configurations will be saved automatically
when the monitor is powered off.
To reduce the hazard of burns in high-frequency surgical neutral connections, the
leads and connectors must be located away from the surgical site. Keep cables away
from other devices.
Ensure that qualified service representatives annually calibrate and maintain the
monitor.
Periodically check all reusable accessories for damage. Replace and dispose of
damaged accessories. When necessary, according to your local hospital waste
disposal regulations.
ECG electrodes are disposable accessories. Always properly dispose of ECG
electrodes according to your local hospital waste disposal regulations.
Clean and sterilize the monitor and accessories according to local requirements.
Turn off the monitor and disconnect the power cords before cleaning or
sterilization.
Keep all monitor packing materials away from children or dispose of them in
accordance with your local environmental regulations.
Always properly dispose of the monitor and all accessories at the end of their
service life. Dispose of batteries according to your local regulations. Never
incinerate batteries or expose them to high temperatures.
Ensure that no water condenses into or on the monitor. Condensation can occur
from changes in temperature or exposure to humidity.

Network setup of the ZD120E Patient Monitor is not user configurable. Please contact
your service personnel.
2.1.4 Monitor Power Supply
You can power the monitor with either an AC power source or its internal battery. You
can switch back and forth between supplies without powering off the monitor.
When the monitor is connected to an AC power source, you can turn on and operate the
patient monitor.
When powered on, the monitor is in normal working condition. It can be used to measure
vital signs, communicate with the central monitoring system, and charge the battery.
When the monitor is in standby mode, the monitor battery is charging.
When AC power is lost, the battery powered monitor continues to run without
interruption on battery power. For more information on battery power, see Chapter 15,
maintaining the Battery.
2.1.5 Inspecting the Monitor
Before you start using the monitor, ensure that:
1. There is no damage to the monitor or the accessory. Before turning on the power,
check the monitor and all the cables, connectors and accessories and ensure that
the extension cables are correctly connected to the fittings.
2. AC power is in conformity with standards. Plug one end of the specified power
cord into an AC power supply with a protection-grounded wire. Plug the other
end into the power connector on the monitor. When the power cord is correctly
connected, the AC power LED is green. If the monitor is powered by battery,
verify that adequate power remains, and the battery power gauge is full.
3. The accessories are correctly connected. For further testing of individual
measurement alarms, perform the measurement on yourself (for example, SpO2)
or use a simulator. Adjust the alarm limits and ensure that you observe the
appropriate alarm behavior.
4. All settings like patient type, alarm limits and so on, are correct. Ensure that the
monitor is in good working condition and that all functions of the monitor meet
the technical requirements mentioned in this guide.
