2 How to use the Prolo kit2 How to use the Prolo kit
Activating the microphone
u Press the In-line PTT, the 2-key PTT, or use the PTT function from the wireless PTT paired
to the junction-box to activate the microphone (figure 8).
Listening
u Place a Profilo Nano earpiece in the ear (figure 9). For more information, please see the
Profilo Nano user guide or contact your local representative. The audio from the radio is
transmitted to the earpiece via the neck-loop (figure 6).
Advices
Prolo WL wirings and Prolo LM wirings can only be used with a Prolo Nano earpiece.
The transmission range is very small and remains in the vicinity of the end-user’s head.
(No risk of message interception.) (gure 6).
The quick-release safety disconnects should be closed correctly to transmit the signal – there
should be no gap between the quick-release safety disconnects (gure 7).
No pairing between the Prolo loop and the Prolo Nano earpiece is needed (any Prolo Nano
earpiece will work with any Prolo loop).
Notes
u The wireless PTT included in the Profilo WL-kit is paired with the junction-box at the
factory. It is possible to pair a new wireless PTT (see Covert Wireless PTT AC user guide) for
both Profilo WL-kit and Profilo LM-kit.
u For more information regarding the wireless PTT, please check the Covert Wireless PTT AC
user guide or contact your local representative.
