Wireless connectivity  
 

Wireless devices are subject to environmental constraints which affect their use.                          
A wireless desk telephone, for example, can have connection/reception difficulties. However it is not less 
useful than a wired telephone!  
Indeed, in some cases linked to the location itself, interferences can prevent the signal from being displayed 
on searching device for a few seconds. It returns in a reasonable period to continue searching.   
 
To make it right; Adopt the attitude of someone who is aware that the wireless equipment has certain usage 
constraints and apply the following advice to your victim search equipment: 
- Place the sensors in view of the control box: Avoid placing them in holes.  
- Position yourself up high with the control box.  
- Leave as much free space as possible between the control box and the sensors: Nobody between the box 
and sensors; the human body creates a natural barrier; do not show your back to the sensors. 
- Consider the weather: depending on humidity/electricity in the air/sun, wireless will work better or worse (eg: 
A radio can emit further in good weather). 
 
Despite these constraints, wireless technology unquestionably has operational advantages which overcome 
them: 
- Rapidity of movements in rubble (no trapped wires).  
- Safety of sensor holder during moves (no imbalance due to trapped wire). 
- Efficiency of the search operations (larger zone covered). 
- Freedom of movement. 
- 30m range on average, much broader than the length of wired sensors (8m in general). 

 

Low battery display  

 

A battery icon 

 

displays above the corresponding graph bar when the batteries of a sensor become low 

(20% remaining power). 
With a low battery level, it increases the risk of disconnections and reconnections. It is therefore recommended 
that you replace the batteries with new ones.  
 
Here, the 3 sensor batteries are low.  

 
 
 
 
 
 

 

 
 
 
 
 
 
 
 
 
 
 

 

It is also possible to view the battery charge level by selecting 

“sensor battery”

 in the menu.
