Silent Call Signature Series Sidekick II Receiver with Backup Battery

When the Silent Call Sidekick II Signature Series Receiver detects an incoming signal from any of the Signature Series transmitters, it alerts you by flashing the strobe light and activating the bed vibrator (if used). The colored alarm indicator light for that signal will illuminate and a symbol for that specific transmitter will display on the screen. Ideal for the deaf and hard of hearing.
