find menu on your phone and search for phone setup then look for rings

go to phillips website and search for your phone

it means you have had a call that's to let you know, go to your handset pick up phone push the middle button with the arrows on it. press up to "call list" then select the - button to the left , that should tell you whos called then scroll throw the list until the light stops, that's who rang you.

Looks like that phone just uses 2 standard NiMH AAA batteries in each handset, which should be available at any retail store.

I have the same problem. New fully charged batteries in philips cd445 run empty without charging. could the be a problem with the contact to the charger? anyone with a solution??? Thanks!

You might have what is called "memory'. If you continue to replace the phone on it's charger after each call the battery will "think" it's empty, giving you s short charge time. Next time you replace the batteries (rechargeable) FULLY charge them then leave the phone off the charger until you go to bed at night.

change the speaker
