call number. You can enter the emer-
gency call number in the “Phone set-
tings: Telephone Option: Emergency

An emergency call will be signalled
for two minutes at the remote end.
The emergency call is made in
hands-free mode; hands-free mode
remains switched on even once the
remote end accepts. If the remote
end is busy then another emergency
call is made once the device (after
approximately two minutes) returns
to the idle state.
