HOW TO USE THE NOISE DETECTOR 

3.1. 

 

DEVICE MAIN PARTS 

 

 

 
 
 

 

If  you  tap  your  finger  on  the  Noise  Detector  casing,  when  device  is  ON,  Red  LED  will 

blink  at  each  hit.  This  is  because  the  noise  generated  by  the  vibration  on  the  chassis,  and  can  be 
used to check if unit is ON and battery works.  
 

 Battery not included: refer to par.3.7 to install the battery the first time on the device.  

 

3.2. 

 

FIRST START-UP 

First always check if Noise Detector is properly working attending the next steps:  
 
1.

 

Switch it ON and check if LED is blinking when tapping on the casing, as explained before.  

 
2.

 

Wear a wet Chest Belt transmitter and check if LED regularly flash on.  
 

 Each LED blinking correspond to each heart rate beat detected.  

 

3.3. 

 

FINDING ELECTROMAGNETIC NOISE 

The HR Noise Detector is really sensitive to all electromagnetic fields produced by the switching 
of  LEDs,  motor  brushes,  the  commutation  of  power  devices,  monitors,  neon  lights,  stereo 
equipment, etc…
