10Ω. The integrity of the lead cable must be checked regularly. Any lead wire damage will cause
a false waveform of the corresponding lead or all leads on the ECG. The lead cable can be
cleaned with neutral solvent. Do not use the detergent or germicide containing alcohol (Please do
not immerse the lead cables in liquid for cleaning).
Note: The resistance of lead cable with defibrillation-proof protection function is about
10KΩ.

9.4.2 Bending or knotting will shorten the service life of the lead cable. When using it, please
straighten the lead cable first.
9.4.3 The electrode should be well stored. After long time use, the surface of the electrode may
oxidize and discolor due to corrosion and other factors, which may affect the signal acquisition.
In this case, the electrode must be replaced.
9.5 Silicone rubber roller
The silicone rubber roller should be smooth and free of stains, otherwise it will affect the ECG
recording effect. In order to remove the stains on the roller, please use a clean soft cloth damped
with a small amount of alcohol to wipe it along the longitudinal direction, and scroll the roller in
the paper conveying direction while wiping until it is clean.
9.6 Cleaning of thermal print head
Dirt and dust on the surface of the TPH can affect the clarity of the waveform. To clean the
print head surface, open the paper compartment cover after turning off the device, use a clean
and soft cloth dampened with alcohol to wipe the surface gently. For the residual stains on print
head, moist it with a little alcohol first, then wipe with a soft cloth. Never use hard objects to
scratch the surface, otherwise the print head will be damaged. Wait until the alcohol has
evaporated, then close the paper compartment cover. The print head should be cleaned at least
once a month during normal use.
9.7 Disposal of product scrap
The disposal of packaging materials, waste battery and end-of-life device should obey the
local laws and regulations, and user should treat the scrapped products and materials properly
according to the laws and regulations, and try to support the classification and recycling work.
9.8 Others
9.8.1 Do not open the device enclosure to avoid electric shock danger.
9.8.2 The device associated circuit schematics and critical parts list are only available to
authorized service station or maintenance personnel, who is responsible for maintenance of the
device.
9.8.3 The device belongs to measuring instrument. User should send the device to national
designated inspection institution for inspection according to the requirements of the national
metrological verification procedure. The device shall be inspected at least once per year, and all
the accessories should be inspected and maintained regularly (at least once every six months).
