are available and pass the information on to the

Warning!
If the indicator lamp in the "SOS" button is
illuminated continuously and there was no voice
connection to the Response Center established,
then the Tele Aid system could not initiate an
emergency call (e.g. the relevant cellular phone
network is not available). The message
"EMERGENCY CALL – CALL FAILED" appears in
the MCS display for approx. 10 seconds.
Should this occur, assistance must be summoned
by other means.
