First, turn on the Answering system, either with the base Answer On/Off button or the handset (Ans. Setup, Ans. On/Off). Next make sure that the memory isn't full. If the message LED reads FL, delete old messages with the handset. You'll need to press the button with the envelope/Mute on it to access the message.

Now, press Menu/Select, scroll through the menu to Ans. Setup. Select this and search for Record Time. Select this and choose the recording time of 1 or 4 minutes. Press Menu/Select again to save the setting.

This is in the manual on page 45. You can get the manual from Uniden at https://www.uniden.com/product-information/owners-manuals . Search for the DECT1580 (the last 5 indicates the number of handsets). The direct link to the manual is https://www.uniden.com/File%20Library/FooterNav/Product%20Information/Owners%20Manuals/DECT1580om.pdf .

I hope this helps.

You have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

In standby mode use up-arrow and down-arrow on the handset or the volume+ and volume- on the base to change the ringer volume.

While on the phone, use the same buttons to change the volume.

If you need a manual, you can download one from the manufacturer's web site at

When you get new batteries for a cordless phone you need to let them charge over night. If you don't the battery will lose its charge much quicker. Now start by charging the batteries followed my plugging the base unit into the phone jack and the electrical outlet. The base unit is what sends out the signals to all the phones and is where your answering machine is located. Once the base is plugged in to the electrical socket and phone jack your phones should start receiving signal again. Make sure the batteries in the phones themselves are plugged in firmly and properly.

If you're talking about the answering machine greeting in the base unit, detailed instructions are here: http://www.uniden.com/pdf/DECT1580om.pdf

If you're talking about the voicemail system provided by your local telephone company, each will be different, but my ATT UVerse voicemail is controlled at http://www.att.com/uversecentral and then click My Account, My Services, U-verse Voice Home Page. Hopefully ATT doesn't shuffle around the menus by the time you read this. This is correct as of Dec 2010.

You can downlaod the manual from uniden in pdf form.

the -4 or -5 refers to how many handsets you set. The 1580 is the actual model number.

To register I think all you do is place them on the master pad once then on their own charger stations. On some models they come all done so you just plug them in charge them up and use them.
