How the R-505 SOS BELLS button works
The R-505 SOS button is super easy to use. A person, slightly squeezing the body of the device with his hand, presses one or both buttons. The buttons start to glow blue. It does not matter how many buttons are pressed – one or two.
The radio signal from the button goes to the call receiver and / or to the pager watch of medical personnel or a caregiver.
The range of the button signal is not less than 200 m in open space and not less than 100 m in a closed room.
The call button is powered by three LR44 batteries installed inside the case. The operating time of the device from one set of batteries is 1 year. When the battery level is low, the LED blinks every 10 seconds.
You will need a thin Phillips screwdriver to replace the batteries. Using a screwdriver, unscrew the hidden self-tapping screw inside the button, open the case and replace the batteries.
