Firmware update via the update server
Push the reset button while in normal operation for 10 seconds.
The power LED starts flashing. Once you release the reset button the telephone
system will call the update server by using external line 1. The telephone number of
the server is pre-set but - if necessary - can be changed via the PC configuration
software's expert mode. LED L1 will go on and LED "Service" will indicate data
communication. The firmware update will take appr. 5 minutes. The firmware will be
transferred as modem signals and will be saved to a buffered RAM. Once the transfer
is completed all incoming data will be verified and in case of a positive result
transferred to the programme memory. All LEDs will go on and off again, one after
the other. As soon as the new firmware has been installed the telephone system will
re-start. After the re-start the Power LED will indicate readiness for operation.
Optional door module
The telephone system can be upgraded by the door module TSM1 that can be
installed within the system's cabinet. I can simply be plugged onto multi-pin
connector on the telephone system's printed circuit board. The door module provides
you with interfaces for a 4 wire door intercom system, a door bell, and a door opener.
The door intercom system as well as the door opener can be operated via internal
telephones connected to the telephone system. With the pharmacy function also an
external telephone (e.g. in another in another street or even another city/country) can
be called via the door bell.
