Safety Precautions
•
Clean the device with a soft,
slightly damp or anti-static

•
When cleaning do not use
cleaning agents or chemical
substances.
•
Only operate the device within
the temperature range of + 5°C

Your telephone is intended for ordi-
nary use. Today's furniture is coated
with a countless variety of varnishes
and synthetics and is treated with a
whole range of preservative agents.
It may be the case, therefore, that
some of these substances contain
elements which attack and soften
the synthetic feet of the telephone.
Terminal feet which have been
modified by foreign substances may
leave unwanted marks on the sur-
face of furniture. Understandably,
the manufacturer cannot be held
liable for this kind of damage. For
this reason please place your tele-
phone (especially on new or re-
treated furniture) on a non-slip pad.
Internal Clock
Your OpenPhone 52 has an internal
clock. This is necessary to display
the date and time in the idle state
and to assign the calls entered into
the call list with the date and time
of their entry.
Immediately after commissioning,
the clock is still inactive and the dis-
play shows neither the date nor the
time in the idle state.
The clock is activated automatically
with the first successful call you
make.
