Setting Airplane mode requires a careful procedure, to be sure that it doesn’t happen by accident.
- Find a quiet place (so probably not just before the plane takes off!).
- Take the band off and hold it close to your ear, upside down (ie with the orange section upwards).
- Press and hold one button for about 7 to 8 seconds until you sense a very short, quiet buzz (the “blip”).
- Immediately release the button, press again and release immediately.
You should sense 3 more blips, but the first may be masked by the click of the button so if you hear 2 but not 3, don’t worry.
If you are doing this within sight of the base, don’t worry that the “Band connect” light doesn’t go out straight away: that won’t happen until the next routine transmission is due.
