Is there on-line manuals I can download for the Bell South CI-36 caller ID unit?

You need to have caller id activated on your phone line and it is a subscribed to feature and is not free. Contact your service provider for more information.

It may be enabled, but normally you have to pay for it.

Page 54 of the manual. It is automatic.

Using Caller ID service
Important: This unit is Caller ID compatible. To use Caller ID features, you must subscribe to a Caller ID service. Contact your service provider/telephone company for details.

Hi. Sorry to hear about the issue you are facing.

Let me try and help you. I think the solution lies in customizing the settings at the - miscellaneous regional settings. Here you can customize various features like time zones, daylight savings rules, etc.
You could find more on this here...

On the other hand, it could be that you might need a firmware and software update. There could be an Answer Anywhere feature that you need to add to your settings. This might fix it. You could get more on this here...

You need a CI trunk card not a LS/DS trunk card for caller id.

You can download the owners manual in PDF format from this link.

412CID 4 Line Telephone

To answer you question - From the owners manual:
Erasing Caller ID Records
In order to delete a specific Caller ID record in the log:
1. Using the [<] or [>] key, find the particular record you would like to delete..
2. Press the [ERASE] key. The LCD display will indicate that the record has been deleted.
3. You may erase all caller information records simultaneously by pressing [ERASE] from the summary
Call ID display.

Hope this Helps.

You dont activate caller id,when you get a call it shows the caller info,if it doesnt,check with your phone company to make sure you have caller id service.
I have the manual you need.

It sounds like your alarm is picking up the phone. How many rings before it picks up?

First off seven to nine you do not use an external cid unit for norstar systems. Make sure you have a caller id card in the main ksu or key service unit( the phone cabinet) It should say CI on it. If the card says DS then you do not have a caller id card on the system and will need to exchange it for one. Then the system phones will have to be programmed for cid.
