Practical setup

Concrete steps to set up a phone, contacts and reminders before you actually need them.

Set up the phone, notifications and actions so they are understandable, then practise the route with its user.

Decide whether the need is retrieving instructions or starting a defined action. Context and individual ability may change the choice.

What remains without internet: shared dependencies, calls and SMS when available, a paper contact card, agreed checks and limits.

Delivered, read, understood and acknowledged are four different states. Ask for explicit ownership and prepare a backup channel.

Speed, confirmation and error prevention: when a direct action helps and when SOS needs confirmation and a countdown.

A readable flow separates choice, recipients, review, and sending without hiding costs, consequences, or alternatives.

Contrast, scalable text, labelled icons, non-colour cues, screen reader, and focus need practical testing.

Hit areas, spacing, cancellation, and practical testing help without diagnosis or a guarantee of accessibility.

Concrete labels distinguish SOS, emergency, ask for help, and “I’m OK” without promising automatic calls or intervention.
