z

 

Common problems 

Problem 1: Blank screen or cannot start up. 
Possible reason: Electricity is used up.   
Solving  method:  Charge  the  battery.  Use  AD-DC  adapter  to  connect  the  equipment  with 
external power supply. 
 
Problem 2: Button can

’

t work properly. 

Possible reason: The button is damaged. 
Solving method: change the button board 
 
Problem 3: data saving aren

’

t allowed. 

Possible reason: SD card is used up. 
Solving method: Export the curve to empty the memory.
