REMOTE: ANSWERING A SERVICE CALL COMING FROM THE EA946 :
Always make sure the persons who could expect a service call from the
EA946
know
of this possibility, can recognise such a service call and know how to answer or
operate in this case !
Answering a service call and remote control of the unit is only possible with a telephone
which can give tone-dialling (
DTMF
tone supported).
After a fault has been detected for a period of time longer then the "ActionTime", the
EA946
starts dialling the first of the (max.) 5 preprogrammed service telephone
numbers. If there is no answer within the set ‘Dial interval time’, it tries the second
number in the list. The
EA946
keeps dialling the numbers in the list until any of the calls
is being answered. A service call coming from the
EA946
can be recognised by an
intermitting tone (DTMF "1") seperated by a approx. 1 sec. break. The amount of
sequential DTMF tones is equal to the identification number set. This should be
answered by pressing any key on the telephone dial pad. If the
EA946
has accepted
the tone-command, the intermitting tone which could be heard stops and now the
service call is answered. You should try to send the command tone in the off-time of
the receiving intermitting tone coming from the
EA946
. If the intermitting tone doesn't
stop, then try to press a key again. After the call has been answered in the correct way,
the
EA946
can then be controlled remotely in listening to the connected audio sources,
rerouting any of these signals to the transmitter, controlling the AUX-source machine
and even force a reset.
