Safety Notes
- Do not connect or disconnect the subscriber´s line of ST 40 during a storm.

- Take care that no liquids spill inside the digital system telephone.This can cause short-circuits.
Regarding this User Guide.
This user manual is valid for the at the time installed system firmware. As the ST 40 is controlled
via the telephone system it may be that after a firmware change some parts of this manual will no
longer be appropriate. This manual will give a brief explanation to the operation of the ST 40 and the
features of your AGFEO Telephone System. For detailed information regarding features, please refer
to user manual of your Telephone System.
The digital System Phone ST 40 S0 is for the connection to an internal S0-Bus of an AGFEO ISDN
Telephone System. The ST 40 may be connected to the following AGFEO ISDN Telephone Systems:
- AS281 All-In-One, AS 35, AS 35 All-In-One from Software 7.0
- AS 40 P (P400-1), AS 4000 (P400-1), AS 100 IT (P400 IT), AS 43, AS 45, AS 200 IT from Software 7.0
The digital System Phone ST 40 UP0 is for the connection to an UP0-Bus of an AGFEO ISDN
Telephone System. The ST 40 UP0 may be connected to the following AGFEO ISDN Telephone
Systems:
- AS 43, AS 45, AS 200 IT from Software 7.5
Please note due to the higher power consumption of the AGFEO ST 40 when connected to the
internal S0-Bus and the limited system capacity for systems already on the market like the AS 40P
(P400-1), AS 4000 (P400-1) and AS 100 IT (P400 IT), it may become necessary to use additional power
supply units. A ST 40 has a maximum power consumption of 1,7 Watt (all LEDS are lit, A Module 40
inserted, with ringer active, volume to maximum) the S0 Bus of an S0 440 module is based on a
double port (4,5 Watt), therefore the max. load is already over the permitted limit with the
connection of 2 x ST 40 and 1 x ST 30 (P max. 1,3 Watt)in the worst case scenario. In such cases the
system may activate the safety protection circuit for the relevant double port. (System Phones /
ISDN Bus without any function. After reset of the system the ports will be reinstated)! In such
eventualities an additional power supply should be connected in order to avoid such failure to occur.
The power supplies are available from your distributor, AGFEO Ref. No. 1542431. (Identical to Power
Supply Unit STE 30 / DECT S0 Base)!
Information regarding software upgrades are available via your dealer.
AGFEO will not accept any liability for damages which may result from improper use of the digital
System Phone ST 40.
