1. INTRODUCTION
Pj20 tracer, hereafter referred to as "device" or "product", is a Bluetooth Low Energy (BLE)
wearable device designed as a technological aid to control the distance between people
(operators in workplaces, museums or events users, etc.) and the tracing of contacts in the post-
emergency management phases of the Covid-19 pandemic.
The Pj20 tracer device, when worn by an operator, is able to detect other nearby devices. When
two or more operators approach each other, the device emits alarm signals based on the
estimated distance, with the possibility of configuring alarm modes (LED, sound, vibration) and
associated distance.
All alarm events, including time information, are saved into the device internal memory, in order
to be subsequently acquired in case of need, so as to have a mapping of the user's contacts in
the period prior to any possible diagnosis of Covid-19 infection.
1.1PROCEDURES
Before starting to use the device, check its integrity and carefully read the indications contained
in this user manual, in particular those in the "Safety" chapter.
Vetrya S.p.A. declines any and all responsibility if the devices are used in incompatible ways and
environments for the product integrity, safety and operation.
1.2INITIALIZATION AND CONFIGURATION
The device needs to be initialized in order to operate. Initialization must be carried out via the Pj20
Tracer Manager Mobile App (currently available for Android) by the staff in charge.
To initialize the devices, after installing the Pj20 Tracer Manager App, the user must log in with
the credentials communicated via e-mail by Vetrya (Figure 1 - Login), bring the tracker close to
the device with the App installed and click on the "Start scan" button to start scanning and track
nearby devices (Figure 2 - Start scan; Figure 3 - Device list).
