Introduction
Also refer to the following documents:
General DECT Handset Information Guide
G355, G955 and I755 Administrator Guide
Notice on the use of the handsets
Like all cordless telephones, the G355, I755 and I755 DECT
handsets use radio signals, which do not guarantee a connection
under all circumstances. Do not rely exclusively on the DECT
handsets when making indispensable calls (such as medical
emergencies).
Mandown feature
The mandown feature of the I755 does not replace companion
supervision by a colleague or other people. In case of critical,
emergency or life-threatening situations make sure that other
persons are present or that appropriate measures are taken.
The functionality of the mandown alarm is based on a horizontal
handset position. Situations can occur in which the end-user
requires help, but the mandown alarm is not activated, because
e.g. the set itself is not in the horizontal position, the wireless
connections are interrupted or radio coverage in the environment
where the mandown alarm is being used, is not sufficient.
SOS function
The SOS function of the G355, G955 and I755 does not replace
companion supervision by a colleague or other people. In case of
critical, emergency or life-threatening situations make sure that
other persons are present or that appropriate measures are taken.
