Try a different position for the base unit-perhaps higher, or further from other electrical

equipment.

The phone does not ring

Check that the base unit's mains power adapter is plugged in and power is switched on. The base

unit needs mains power for normal operation of the phone-not just charging the batteries.

Make sure you are using the telephone line cable that was supplied with your DDP-650. Other

telephone line cables might not work.

Check that you have set the ringer volume to off. See the user manual for more information..

Check that the total REN value of all equipment connected to your telephone line is no more than

4. Disconnect one or more telephones and see whether that helps.

When I press the CALL button, I hear a loud noise.

The strange noise is caused by interference. Disconnect the mains power lead from the back of the

base unit, and then wait for 30 seconds before reconnecting it.

There is 'beep' sound while I am on a call.

You may be going out of range of the base unit. Move closer, or your call may be cut off.

Check the Battery Level symbol on the display. If it is low, recharge the batteries.

The Caller Display feature isn't working.

You need to subscribe to the Caller Display feature from your service provider.

The caller may have withheld their number, or they may be calling from a network that does not

transmit the Caller ID (for example, it may be an international call).

The handset's battery is running low within an hour or two.

Before you used the handset for the first time, you should have left it on the base unit for up to 15

hours to charge the battery fully.

You may need to replace the battery.

I cannot transfer a call.

Make sure the other handset is within range of the base unit, and is not busy on a call.

Make sure you are keying in the correct number for the other handset.

I cannot register handset to base

Make sure the number of handset registered to base is not more than 4.

Check that the base unit is not near other electrical equipment, such as TV or computer
