Troubleshooting
Check that the telephone cord is undamaged and properly plugged in. Disconnect any
additional equipment that may be connected, eg. extension cords and other phones. If the
problem is resolved, the fault is with the other equipment.
Test the equipment on a known working line (eg. at a neighbours). If the product works then
the fault is with your telephone line. Please inform your local telephone company.
No number shown when ringing
- This function requires a subscription from your service provider.
- A switchboard cannot usually pass on incoming numbers.
Warning signal during call/Cannot connect
- The batteries may be running low (recharge the hand unit).
- The hand unit may be (nearly) out of range. Move closer to a base unit.
Telephone does not work
- Check that the adapter and telephone cord are connected to the base unit and to their
respective wall sockets.
- Check that you have selected Tone Dial, see System Settings/Dial.
- 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 this equipment is faulty.

- Check that the adapter and telephone cord are connected to the base unit and to their
respective wall sockets.

The answer machine does not respond to remote control
- Check that the telephone you are using to remotely control the answer machine is a tone
dialling telephone.

If the telephone still does not work, contact the place of purchase. Don’t forget the receipt or
a copy of the invoice.
