The Set HL 675 is ideal for transferring Timing Data and Impulses. 
Its 500mW emitting power and its licence free frequency range (869 Mhz) makes this device a powerful 
and simple to use system. 
 

  Data / Impulse transmission system (500 Mw) which does not require a licence (free of use) in Europe 

(ISM Band 869 MHz – 

REC 70-03

). 

 

 Each 

Receiver

 can receive Impulses (simultaneously or not) from 4 

Transmitters 

identified by the 

function "

CHANNEL

" (1 to 4). 

 

  Up to 4 Teams can work (train) in the same area without disturbing each other thanks to the function 

"

TEAM

" which offers the possibility to code each system (A, B, C, D). 

 

  It is also possible to use up to 16 

transmitters

 with 4 

receivers.

 

 

 When 

the 

receiver

 is switched on, it is possible that one or more green LED’s are on before that the 

transmitter(s)

 start to transmit. This detection system allows visualization of the quality of the 

received signal, but also the possible interferences coming from other radio transmission systems. If it 
is not possible to stop these interferences by moving the 

receiver

, the transmission of Impulse cannot 

be guaranteed.
