(Main

 

Device) 

The three-view diagram of the QT ECG Recorder is shown in Fig 3.1.1a To

 

 

   

 

 

 

   

   

 

 

 

turn on/off the QT ECG Recorder, press and hold the power button for 5

 

 

 

 

 

 

 

 

 

 

 

 

   

seconds. The Power (PWR) LED indicator will turn solid green when the

 

 

 

 

 

 

 

 

 

 

 

 

power is on. The QT ECG Recorder has two ports; one is used to connect

   

 

 

 

 

 

 

 

 

   

   

 

with the Electrode Strip, and the other is used for charging with a Micro

 

 

 

 

 

 

   

 

 

 

   

 

USB wall charger (Fig 3.1.1b & Fig 3.1.1c). Do not attempt to charge and

 

 

 

 

   

 

 

 

 

   

 

 

plug-in the Electrode Strip at the same time. Do not use any charger

 

 

 

 

 

 

 

 

 

 

 

 

 

other than the one provided in the original case. Do not attempt to

 

 

 

 

 

 

 

 

 

 

 

 

 

connect the QT ECG Recorder with any other cable, connector or power
