that bare parts of the electrodes and the patient do not come in contact with
conductive parts, such as metal examination beds, trolleys, and similar items.

Before defibrillation, always disconnect the ECG cable connector from the
system and make sure the connector does not come in contact with other
persons or conductive surfaces, such as metal examination beds, trolleys,
and similar items.

Operating your system with ECG signals below 0.25 mV may cause
inaccurate results.
Warnings
– TEE Transducer

The multiplane TEE transducer should be used only by a qualified physician
who has received appropriate training in proper operation of the probe and in
endoscopic techniques as dictated by current relevant medical practices.

Electrical Hazard: Any evidence of damage indicates the probe cannot be
used and should be returned to Mindray/Zonare for evaluation and repair.

Biological Hazard: Adequate cleaning and, if necessary, disinfection are
carried out to prevent disease transmission. It is the responsibility of the user
to verify and maintain the effectiveness of the procedure used. A single-use,
sterile disposable sheath for TEE purposes can be used.

Inspect the transducer connector pins for contamination or damaged pins that
might interrupt signal flow through the connection. Be sure to check pins
before connecting transducer to the Mindray/Zonare ultrasound system. If
pins are bent, broken, or missing, do not use the transducer and call
Mindray/Zonare Technical Support.

Immediately replace a transducer that exhibits any damage symptoms.

Before introducing the probe, do not rub or spray the tip of the probe with an
anesthetic agent.

Avoid forceful manipulations and excessive force in using the probe that could
result in patient injury.

Withdraw the probe only with the deflection control in the unlock mode and
with the distal end of the probe straight.

The use of a bite guard is mandatory. Failure to use the bite guard may result
in damage to the probe, which could result in a safety hazard. Damage to the
probe due to biting is not covered by the probe's warranty.

Check if the maximum deflection of the tip is 90° to 120° upward, 60° to 90°
downwards and 30° to 45° left/right. If the deflection shows an unwanted
amount of free play or exceeds the maximal deflection angles given above,
do not use the probe. Contact the service organization to re-adjust the
steering of the probe. In this way, the risk of "buckling" or "U-turning" of the
probe in the esophagus is minimized.

Avoid damage to the probe by allowing nothing to protrude beyond the case
when closing the lid.

Prior to cleaning any device, turn off the system and disconnect power cord
from AC power source to avoid electrical shock.

Always use protective eyewear and clothing when cleaning or disinfecting the
transducers.
