Check that the telephone cord is undamaged and properly plugged in.

Disconnect any additional equipment, extension cords and other telephones. If

the problem is resolved, the fault is with the other equipment.

Test the equipment on a known working line. If the product works then the

fault is probably with the line. Please inform your local telephone company.

No Number Shown in Display When Ringing

In order for this feature to function, you must subscribe to the Caller

Identification service from your network provider.

- If a text message shows on the display, the call may be an international call

(no data received), or from a private or blocked number.

- If MOBILE is displayed, the network operator has generated this call

description as a name. The display will alternate between MOBILE and the

number transmitted. The mobile number will not display if barring is active

on the calling mobile.

- If PAYPHONE is displayed the network operator has generated this call

description as a name. It is unlikely to receive an associated number with

calls from a payphone.

It may not be possible to receive CID information if the phone operates in a

PBX system.

Warning Signal While Talking/Cannot Connect

The batteries may be running low (recharge the handset).

The handset may be (nearly) out of range. Move closer to the base unit.

Telephone does not work

Check that charge contacts in handset and base unit are clean.

Check the adapter, is it correctly connected to the base unit and to the mains

power?

Check that the telephone cord has been correctly connected to the base unit

and to the line socket.

Check the charge status of the handset batteries.

Try connecting another telephone, known to be in working order, to the line

socket. If that phone works, then it is likely that the equipment is faulty.

If the telephone still does not work, contact Doro support or the place of

purchase. Don't forget the receipt or copy of the invoice.
