User Manual – EC II GSM SE 13
It is very important that the EC II GSM SE has the best possible GSM-signal to prevent com-
munication disturbances. Find the best possible position before mounting of the central unit.
Place a standard mobile phone in the imagined site of erection, make a speech connecting
call and run the lift slowly through the whole lift shaft. If there is a disturbance or interruption
of the call – choose another position and do the whole procedure again. Make sure that the
same operator is used which is intended to be used by the EC II GSM SE.
It is also possible to mount the central unit in the machinery room if no good GSM signal is
available on the lift car roof. Then the modular cable between the speech unit and the central
unit must be replaced by an 8 wire lift cable, preferable with twisted pairs. Cut the modular
cable in the middle and connect all wires using a screw connector to the lift cable to be used.
