Troubleshooting
Check that the telephone cord is undamaged and properly plugged in.
Disconnect any additional equipment that may be connected. 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
with the line. Please inform your local telephone company. Check that charge contacts
in handset and base unit are clean
No number shown in display when ringing
- In order for this feature to function, you must subscribe to the Caller ID service
provided by your network operator.
- If a text message is shown on the display, the call may be an international call (no
data received), or from a private or withheld number.
- It may not be possible to receive Caller ID information if the phone is connected to
a PBX system.
SMS does not work
- In order for this feature to function, you must subscribe to the service provided by
your network operator.
- Check that the right number is stored for the service.
Warning tone during call/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 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 the place of purchase. Don’t forget the
receipt or a copy of the invoice.
