Precautions about Waterproof
CAUTION
 Replace the “Battery Compartment Lid” of the LX-7120(G) regularly to
keep the performance of waterproof. If not regularly replaced, the quality
of the lid will deteriorate and cannot keep the waterproof performance.
For details about the regular replacement, contact your local Fukuda
Denshi service representative.
 The lid may be damaged from high impact. If the LX-7120(G) is dropped
or is subjected to a high impact, make sure that the lid is not damaged.
 Do not use the LX-7120(G) wet. Always wipe the LX-7120(G) with a soft
cloth and dry it thoroughly before use.
Precautions about ECG
CAUTION
 When removing electrodes from the patient, remove them carefully and
slowly. Do not apply excessive force to remove them. Otherwise, it may
damage the skin.
 There are some cases when the pacemaker pulse cannot be detected
depending on the pacemaker type, pulse voltage, pulse width, electrode
lead type (unipolar, bipolar), electrode placement, or lead method which
causes the pacemaker pulse amplitude to decrease and disables
pacemaker pulse detection.
 If signals similar to a pacemaker pulse are present, such as electric
blanket noise or excessive AC frequency noise, these may be
erroneously detected and displayed as a pacemaker pulse. In this case,
check the condition of the electrodes and ECG lead cable to resolve the
cause or turn off the pacemaker detection setting on the receiving
monitor.
Precautions about Output Signal
WARNING
Do not use the output signal of the monitor that receives radio wave signal
from the LX-7120(G) as the trigger signal for IABP, MRI
echocardiographic, or defibrillator for the following reasons.

It may lead to a delay of operating timing due to the delay time of
waveform transmission.

A trigger signal unrelated to the heart rate may be generated due to
the interfusion of spike noise at weak electric field.
