water or natural cleanser and gently wipe down the recorder. The QT ECG
Recorder should not be immersed in water under any circumstances. Take
care not to scratch the device with abrasive cleansers or excessive wiping on
the label. The QT ECG Recorder should be gently cleaned before every use. To
disinfect the QT ECG Recorder, dampen a soft cloth with isopropyl alcohol and
gently wipe the Recorder. Regularly inspect the QT ECG Recorder for damage
such as warping or cracking. If there is any damage, do not use the QT ECG
Recorder and contact QT Medical customer service.
The following sections describe how to clean the QT ECG system, including

Solution : Check the corresponding limb/chest electrode(s). Make sure each
electrode is attached properly to the skin and making good physical contact.
Firmly press on the area of the strip indicated in yellow to ensure good
electrode contact with the skin.
press firmly down on the strip to ensure it is making good skin contact.
If this does not resolve the problem, ensure the skin is clear. If there is
hair in the electrode strip area, shave along the indicated area. If the skin
is oily or dirty, try wiping down the skin under the electrode strip with a
clean cloth.
In a low humidity environment, electrodes may dry up, preventing
adhesion to the skin. If the electrodes have been stored in a dry
environment, and a "lead-off" alert is shown in the app during use,
please use a moist cloth to dampen the hydrogel circle(s) of unattached
electrode(s) indicated in the app alert, then reattach the electrode.
If lead-off remains, but the hydrogel circles has been dampened and strip
firmly contacted to skin already.
Please try the following steps:
1. Take off the strip and re-attached to skin,
2. Unplug the connector and plug in again.
3. then reboot the recorder and try again.
If lead-off remains still after all the process, please contact us.

attached properly but shows leads off, please use a moist cloth to
dampen the hydrogel circle(s) of these electrode(s) indicated in the app
alert, then reattach the electrode.
