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. (

 page 6). 

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 

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.
