Calling Black Box; Shipping And Packaging - Black Box TE120A User Manual

4- AND 8-LINE CALLER ID
Caller ID data for some or all lines is garbled.
• Make sure that the data rate and data format settings of your Caller ID units
match those of the DTE and each other (see Section 3.2).
• If only one of the four or eight lines of a Caller ID unit is malfunctioning,
check the unit's DATA LED to see if it flashes when data is sent. If it isn't,
there might might be a problem with the RTS signal, or there might be a
hardware fault somewhere.
• If you're daisychaining, make sure that the unit numbers of all of the Caller ID
units are set correctly (see Section 3.2).

6.3 Calling Black Box

If you determine that your Caller ID unit is malfunctioning, do not attempt to alter or
repair it. It is not user-serviceable. Contact Black Box Technical Support at 724-746-
5500.
Before you do, make a record of the history of the problem. We will be able to
provide more efficient and accurate assistance if you have a complete description,
including:
• the nature and duration of the problem;
• when the problem occurs;
• the components involved in the problem;
• any particular application that, when used, appears to create the problem or
make it worse; and
• the results of any testing you've already done.

6.4 Shipping and Packaging

If you need to transport or ship your Caller ID unit:
• Package it carefully. We recommend that you use the original container.
• If you are returning the unit, include everything you received with it. Before
you ship the unit back to Black Box for repair or return, contact us to get a
Return Authorization (RA) number.
