Instructions to setup device

• Power on.

• Connect your phone/tablet/computer to Wifi device "ClockMessageBox".

• Connection password is "password".

• When successfull open browser and goto 192.168.4.1

• On some devices the auto-capture will work differently. For example, on my Android device it asks me if I want to sign in to this device, this then takes me to the config page.

• Select the Wifi device you want it connected to (probably your home router).

• Enter the password for that device.

• Read the instructions on the page to tell if it was successfull or not.

• If not repeat.

• When successfull the Clock Message Box will save the connection and (attempt to) automatically connect to this every time it powers on.

• On power-up the Clock Message Box should display the IP it has been assigned.

• Open browser and goto that IP to send the box messages.

• ( To display the IP again touch the front button. )

• ( To clear a message touch the front button. )

• ( Message will timeout and revert to clock (currently) after 1 hour. )

• ( Clock Message Box will attempt to update date and time everytime it powers on. )

• ( Clock Message Box automatically adjusts for UK daylight savings. )
