Emergency Number
Public telephone networks in countries around the world have a single emergency telephone
number (emergency services number), that allows a caller to contact local emergency services
for assistance when necessary. The emergency telephone number may differ from country to
country. It is typically a three-digit number so that it can be easily remembered and dialed
quickly. Some countries have a different emergency number for each of the different emergency
services. The emergency number setting, if desired, must be made before lock activation. For
