This battery-operated unit receives signals from any Silent Call Legacy Series transmitter which in turn causes a vibration and turns on an indicator light below the symbol to let you know which transmitter is sending the signal. Easy to wear on the waistband of slacks or skirts. Rechargeable 9-volt battery is included - requires Battery Charger to increase battery life. A fully charged battery provides around 35 hours of continual use.
