Warning melodies
Your alarm unit provides visual and acoustic warnings when the battery voltage is too low or you move out of range.
J Low battery warning during a call:
One acoustic signal per minute is issued when the battery charge
drops below half of the full capacity during a call.
K Low battery warning in Standby mode:
One acoustic signal per minute is issued when the battery charge
drops below half of the full capacity in Standby mode. In addition,
the red LED flashes.
If the battery charge drops below half of the full capacity, an alarm
is sent to the services exchange. A message is then sent from
there indicating that the batteries must be recharged.
L Range warning:
If the unit is moved out of range, an acoustic warning signal is
issued and the red LED flashes. Move closer to the base station
to retain the connection.
