Installation
Dialog 4187 Plus 96
Charging procedure before use
At installation or if the telephone has been disconnected, it requires
a charging time of approx. 30 seconds before fully operational.
During charging the display is empty. When the telephone is ready
to use, the display is turned on.
Note: Charging should take place with the handset on
hook.
CallerId Detection
During installation of the telephone, the CallerID detectors for both
DTMF (Dual-tone multifrequency) and FSK (Frequency-shift keying)
are activated until the first CallerID is received. If Message Waiting
signals are received by the telephone during this time, this will
cause the display to dim. This effect will stop after the first call has
been received.
Placing the telephone
• Do not place your telephone on sensitive surfaces. Use a
non-slippery pad to protect your furniture from possible
damage.
• Do not place your telephone near sources of extreme heat,
e.g. near the radiator.
• Make sure that the line cable isn´t creased.
Cleaning the telephone
Use a slightly moistened (not wet) soft cloth or an anti-static cloth
and wipe off the telephone carefully. Do not use rough cloth,
solvents or aggressive cleaning fluids. Any damages of the
telephone, that are caused by non-observance of these
instructions, are not part of the liability given by the manufacturer.
