Changing the dialling mode/
flash time
The telephone supports the follow-
ing dialling modes:
Depending on your PABX, you may
need to change your telephone’s
dialling mode or the flash time.
Temporary tone dialling switching
in "Pulse" position
To use functions that require tone
dialling (e. g. remote control of
answering machine), you can set the
telephone to tone dialling for the
duration of the call without adjust-
ing the switch.
After the connection is established:
Press the star key.
After the connection is broken, the
setting reverts to pulse dialling.
Operation on public
telephone systems
Public telephone systems - in some
cases by special order/request – offer
you a range of useful additional ser-
vices (e.g. call divert, call back on
busy, three-party conference etc.).
These services can be selected using
specified key combinations, which
your network provider will notify you
of.
You can save the entire key combina-
tion, including the number of a fixed
call divert destination, to your speed
dial keys just like a normal number.
Recall key
In public telephone systems, the
recall key is required to use certain
additional services; e. g. for "Call back
on busy".
You may need to adjust the flash
time of your telephone to the needs
of the public telephone system. Use
the sliding switch on the back of your
base station. (
Appendix
Care
Wipe the device with a
slightly mois-
tened
cloth or an antistatic cloth. Do
not use solvents or microfibre cloths.
Never
use a dry cloth; this can cause
static.
In rare cases, contact with chemical
substances can cause changes to the
device’s exterior. Due to the wide
variety of chemical products availa-
ble on the market, it was not possible
to test all substances.
Impairments in high-gloss finishes
can be carefully removed using dis-
play polishes for mobile phones.
Contact with liquid
If the device comes into contact with
liquid:
1
Unplug all cables from the de-
vice.
2
Allow the liquid to drain from the
device.
3
Pat all parts dry,
4
Place the device in a dry, warm
place
for at least 72 hours
(
not
in a microwave, oven etc.) with
the keypad facing down (if appli-
cable).
5
Do not switch on the device
again until it is completely dry.
When it has fully dried out, you will
normally be able to use it again.
