Need to test a bizfon system prior to purchasing


I hope you might be able to help me figure out how to test a used bizfon 680 system before I buy it. I notice in the control unit has an empty dimm slot that accepts standard Dimm 100 memory chips. The unit does nothing when hooked up to a phone line with dial tone. The extension phones are also hooked up and their power supplies connected to power.

There is no dial tone to any phone and the unit does not answer a call when dialed from an outside line.

Is the missing DIMM to blame or is it an add on for upgrade purposes?

Any help will be appreciated. Thanks,

Used Dell M1330 sold to me as a new computor

Hi there!
Check first if the computer is under your name or under best buy, if it is under your name and you have a warranty the definitely DELL should help you,
But if it is under best buy, then best buy should be able to help you with your problem, as long as you have the warranty with the computer.

Hope this helps!

Do you know what type of cable is used as the network cable and the expansion cables on a bizfon 680?I would like to make these cables myself or if they are just ethernet or crossover cables? If so which...

The in/out uses a standard network cable, and the network port uses a crossover cable (unless you want to use a network switch then standard network cables are used)

Remote control for Z-680

I have 2 sets of speakers systems for the Logitech Z-680
Both sets included Subwoofer and 5 speakers.

Note: there is no controller on both just the speakers

I bought one set and the Controller went out.
Logitch sent me a new Z-680 system then the second controller went out but speakers work great.
1 system speakers were never used
2 system speakers used for about 4 yrs (speakers work great)

Also have 2 remotes (never used)

Both speaker systems are for sale
Remotes will sell seperatly or with systems

If in need of the subwoofer speakers must go along

Email me if interested
