Why does the line 'Base n' flash on my Siemens Handsets?

  samuelparkerAug 19, 2025
  If the Siemens handset displays 'Base n' flashing, it could be due to several reasons: the handset is out of the base radio range, the radio signals are too weak, the handset isn't registered, or the intervals between synchronization attempts are too long. To resolve this, try moving closer to the base radio range or changing your position. You might also need to register the handset or try switching it off and then back on.
