LS Transponder


NO SUBSCRIPTION REQUIRED | Product card | Register your product

The Protime LS transponder is delivered with a Lithium-ion battery or with a direct connection to the vehicle’s battery.

When the transponder is in the charger, the power down is automatic, which offers an autonomy of several months. Only one charge per year is necessary to maintain the transponder in good working condition.

The transponder has 5 days autonomy when it is continuously used. The tricolor LED indicates the level of charge and the autonomy.

The information on the level of charge is sent to the decoder when the transponder passes over the loop.
