20 Most Recent AT&T Merlin BIS 10 Phone Questions & Answers

It should have a slider on one of the sides. Set it to "low" or "off"

The display will blink if power is cut either by unplugging or if the control system is power-cycled. The cause of the power glitches needs to be located & corrected. Changing the ring tone/cadence depends on which control unit is being used.

You would need to subscribe to your local service provider's call forwarding service....or....if the controller that the phone is connected to has that feature, refer to the system documentation for the procedure to activate/deactivate it.

No.

The BIS 10 and related telephone units need to be connected to one of the following AT&T Merlin telephone systems:

AT&T Merlin 206
AT&T Merlin 410
AT&T Merlin 820
AT&T Merlin 820D2
AT&T Merlin 1030
AT&T Merlin 3070
AT&T Merlin II (With the proper modules installed)
AT&T Merlin Legend (With the proper modules installed)

There should be a slider lever on either the left or right side edge (I don't remember off the top which one it is) that adjusts the volume of the ringer. The cadence is changed in the programming of the control unit that the phone is connected to. The programming is different for different systems so the best solution is consult the phone system's documentation.

That depends on the system that the telephone is connected to. You would need to determine which system you have and then consult the owner's manual/programming guide. If your system is being maintained by a vendor, they should be able to make the programming changes for you.

There should be a slider lever on either the left or right side edge (I can't remember which one it is) of the unit that will adjust the volume.

It depends on how the control unit is programmed. The BIS 10 can't be used as a stand-alone phone (as in....you can't connect it directly to a telephone line).

The BIS 10 will work with the following systems:

AT&T Merlin 206
AT&T Merlin 410
AT&T Merlin 820
AT&T Merlin 820D2
AT&T Merlin 1030
AT&T Merlin 3070
AT&T Merlin II (with the proper modules installed)
AT&T Merlin Legend (with the proper modules installed)

Assuming that the problem is isolated to 1 particular extension, if you have a known working set, try switching that one for the new one and see what happens. If the problem follows the phone, try switching the handsets. If that doesn't work, replace the phone.

If he problem stays with the port on the telephone system, check the wiring and/or plug the telephone directly into the port on the system. If the problem remains, then the extension/port on the system is bad.

Western Electric produced 2 different stands for "Classic Merlin" telephone sets. You will need to locate the stand designed for wall mounting. Such stands appear on eBay from time to time. Keep in mind that Classic Merlin telephone sets were discontinued many years ago so locating the correct base might be a bit of a challange.

By the part number. BIS means Built-In-Speakerphone. So a BIS has a mic. Try the right side front.

You might take an electronic device and plug it into the outlet where the Merlin was plugged in. I doubt it , but it could be a power outlet failure. other then that Merlin 410's can still be purchaced on the refurbished market.

If you are getting busy signal, something is shorted out.

Disconnect the wiring from the phone systems page port, and try to page. did the busy go away?

if not the port is bad in the phone system. If it did, the page pac is bad...

Depends on what system you have that phone installed o.

If Merlin Legend, on the left side of the phone there is a 3 position switch. Its in the middle position now.

Slide that down
press on of your lines
Press *347

Slide the switch to the middle position.

If that doesnt work, we need to know the system you have these phones on.

Al the programming for the phone and voice mail are held within thier respective systems. Changing one BIS 10 for another will not delete any programming.

If you have a "squared" system (each line assigned to a different button), just press a different line button. To change the order of the lines, slide the "T/P" switch to "P" and press the line buttons in the order you want to use them (ie: Line 4, Line 3, Line 2, Line 1).

If your lines are "pooled" you just get the next available line from the pool - no choosing which line you get.

Hope this helps.
