cluded into a new edition of Operation Manual.
1 Function
1.1 The bracelet is asmall-sized radio transmitter provided with
an independent battery, and designed to generate and transmit
encoded signals upon pressing a button.
1.2 Encoded signals shall be transmitted after the button is
pressed. The LED indicator illuminating within 2-3 s. denotes sig-
nal transfer.
1.3 The indicator will flash on each 2s within 0,2s for a period of
5 min. confirming to the police that the button
was pressed, and that the activation of the but-
ton wasn’t false.
1.4 The bracelet will stop transmitting signals
in 20 seconds after pressing the button, regard-
less of how long you press the button, even if it
is still pressed.
1.5 The bracelet is powered from a 3V battery,
type СR2430.
1.6 If light intensity is inferior and the LCD in-
dicator blinks when the button is pressed, it in-
dicates that the battery in the bracelet is low.
1.7 The manufacturer guarantees a minimum
communication range 50m between Astra-RVC
receiver (hereinafter referred to as receiver) and
the bracelet in line of sight in the area with dry
ground in the absence of strong radio interference, and objects in-
terfering with and reflecting radio waves. The communication
range between the receiver and the bracelet can be cut down to
30m inside concrete buildings and in presence of radio interfe-
rence.

5 Registration of the Bracelet in Receiver
Memory
5.1 After transportation in conditions differing from those of
operation keep bracelet unpacked under supposed operation
conditions for at least 2 hours.
5.2 Bracelets shall be registered in turns in any order. In case
of successful registration, receiver will “save” in its nonvolatile
memory a unique factory number of the bracelet, and will
attribute a serial number in the order of registered bracelets.
An illustrated manual describing registration of bracelets is
provided in Appendix A.
5.3 Clear the receiver memory before registration of the first
bracelet.
1) Remove the front cover from the receiver by pushing a base
clip from the cover slot.
2) Install jumpers on F1 and F2 plugs.
3) Power the receiver up.
4) A green receiver indicator will blink once per 4 seconds.
5) Press and hold the button on the receiver until the green indi-
cator is off. The receiver memory is clear.
6) Power the receiver off.
5.4 Registration of First Two Bracelets
1) Remove the front cover from the receiver by pushing a base
clip from the cover slot.
2) Install jumpers on F1 and F2 plugs of the receiver.
3) Power the receiver up.
