To use Touch Siren, you must activate the NFC feature of your smartphone to the default mode.

From the home screen, scroll down twice from the top to open the 'Quick Settings' panel.

Check if the 'NFC' icon is activated in 'Default Mode'.

After unlocking your smartphone,touch the central part of the back, marked in blue, to the safe bell touch area.

If your smartphone has accessories like grip talks, finger rings, thick cases, or metal cases attached, it is recommended to remove them as they may reduce recognition rate.
