Connection and conditions for use
You can connect your DDP-650 to a direct exchange line (DEL), a line connected to a local
exchange, with its own phone number; to an extension socket connected to a DEL; or to an
extension on an approved compatible PBX. Do not connect the DDP-650 as an extension to a
payphone.
How many phones can you connect?
The ringer equivalence numbers (RENs) of all instruments (phones, fax machines, etc.) connected
to an exchange line must not add up to more than 4, otherwise, one or more of them may not ring
and/or answer calls correctly. The DDP-650 has a REN of 1, and most other telephones have a REN
of 1unless marked otherwise.
Radio signals between handset and base unit
To use your handset and base unit together, you must be able to establish a radio link between
them. Be aware that:
•Sitting the base unit as high as possible will give better results, in a two-storey house, the
best position may be on the first-floor landing.
•Any large metal object, like a fridge, a mirror or a filing cabinet, between the handset and
base unit may block the radio signal.
•Other solid structures, like walls, may reduce the signal strength.
Choosing a site for the base unit
The base unit should be placed on a level surface, in a position where:
•The mains adapter plug will reach a 230-V AC switched mains supply socket; never try to
lengthen the mains power cable.
•The telephone cable will reach your telephone line socket or extension socket.
•It is not close to another telephone, this can cause radio interference.
•It is not close to other electrical equipment, fridges, washing machines, microwave ovens,

your line so that you can make calls during a power failure)
People with a heart pacemaker should consult their doctor before using the telephone.
If you wear a hearing aid, you should note DDP-650 works by transmitting radio waves between
base and handset that may cause a humming noise.

TROUBLESHOOTING
Always check first that:
•You have followed the steps listed on pages to install and set up your DDP-650.
•All connects are firmly inserted in their sockets.
•Mains power is switched on at the socket.
•The handset’s batteries are correctly and securely installed, and are not run down.
If you experience difficulties with the working of your DDP-650, refer to the advice given below.
I cannot make or answer calls.
Check that the handset unit’s mains power adapter is plugged in and power is switched on. The
handset 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 the battery level symbol on the display. If it is low, replace the handset on the base unit or
charger pod to recharge the batteries.
Switch off power at the mains socket, wait for a few seconds and then switch back on. This may
solve the problem.
If you still can’t make calls, try re-registering the handset.
When I press keys on the handset, nothing happens.
Make sure the batteries are fitted in your handset. If the battery level symbol on the display shows
“low”, recharge the batteries.
Check whether there’s a key symbol on the display. If so, the keypad is locked. Turn to the user
manual to find out how to unlock it.
When I press keys on the handset, digits appear on the display, but I can’t
make an outside call.
Call barring may have been set, see the user manual for more information.
Try moving the handset closer to the base unit.

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
