FAQ

1/ I have no dialling tone after having installed my phone. How do I solve this problem?

Check that you have connected your phone using the supplied line cable and not the one from any previous phone (they are often wired differently).

Check that you have fully charged the handset according to the instructions given for the phone.

Check that the aerial icon (radio link with the base station) is displayed. If the handset is not registered you may need to register it (see p.28).

2/ Can the handset be left on the base all the time?

Yes there is no“memory effect”.The handset can be left on the base station for all current models using NiMh batteries.

3/ Will my phone lose all recorded data (phonebooks entries, recorded messages) in the case of a general power cut?

No it will not.The data recorded in your phone is not deleted in the case of a general power failure or when you unplug your base station or when you replace the batteries.

4/ I have set up the date & time on my phone and the information given after a call is not correct. Why?

If you have a ISDN phone installation, these parameters (date & time) may be transferred directly through the ISDN to the phone. If you did not set-up the ISDN correctly this can explain why the information transmitted is not correct. Set-up the date & time directly on the ISDN phone installation or, if this is not possible, call the Operator/dealer who provided and installed the ISDN.

5/ I cannot use the answering machine of my Philips phone together with my Fax plugged into the same line, why is this?

To avoid this, it is recommended to set up the number of rings before the answering machine switches on. Example: if the network mail box or a fax is set to answer the calls after 4 rings, please set up your answering machine on 3 rings.To set up the number of rings, please see p 34.

6/ What is CLI and how do I make it work?

CLI stands for Caller Line Identification and it is a special service that you may subscribe to from your network operator. Once you have subscribed to the service, a CLI enabled phone will display the callers number (unless withheld) as the phone rings so that you may decide whether or not to take the call.

7/ The CLI service does not work on my Philips phone, on my digital phone installation (ISDN, ADSL). How do I solve this problem?

Our products are designed to work on an analogue network. If you plugged your PHILIPS phone into a digital installation, the CLI may not be displayed upon incoming calls. Digital phone installations (ISDN) are not always compatible with analogue phones as far as operator services are concerned.

You may find the information regarding compatibility in the user guide of your ISDN. If not, please contact the ISDN manufacturer to check if the device is designed to display CLI on analogue phones. ISDN over 2 or 3 years old are generally not compatible with analogue phones for the CLI Service.

Note that the filters used with some ADSL lines can filter out part of the CLI signal and prevent the phone from displaying CLI correctly. It is possible to purchase better ADSL filters that do not cause this problem.
