Label MakersEach NBX Telephone and NBX 1105 Attendant Console comes with a set 
of blank labels that you can write on to identify the buttons to which 
Speed Dials and other unique settings have been applied. When you are 
setting up many telephones with similar features, you can use the 
multiple-label files on the Downloads tab. 
To print labels from the LabelMaker files, you need Adobe Acrobat 
Reader. A free copy of Acrobat Reader is available at www.adobe.com
 
and on the NBX Resource Pack CD-ROM. The LabelMaker files are 
compatible with Acrobat version 4.0 and 5.0.
Adobe Acrobat Reader cannot save a file, so after you close a label 
maker, you cannot open it and print again. You must recreate your edits. 
To save your edits, you must purchase the complete Adobe Acrobat 
application. See www.adobe.com
.
To create sets of Label Makers, select Downloads > Label Makers.
See the Help for procedures on making multiple labels.
A file to create a single set of labels is on Personal Settings > Speed Dials. 
The file can create a set of labels for either the NBX Business or Basic 
Telephone.
Quick Reference 
SheetsQuick Reference Guides are shipped with each telephone, analog 
terminal adapter, and NBX 4-Port Analog Terminal Card. You can also 
download and print a copy of the Adobe Acrobat PDF version of each 
quick reference guide from the Reference Sheets tab. You can download 
Adobe Acrobat Reader from the NBX Resource Pack CD or from the 
Adobe web site at www.adobe.com.

Using H3PingIPYou can use the H3PingIP menu item to ping another device on the 
network to test the telephone’s connectivity and to check the packet 
delay. 
When using H3PingIP to test for connectivity, you must use the IP address 
of a device that is connected to the NBX system NCP. You should not use 
the NCP IP address. The NBX Business Telephone uses the IP Gateway and 
subnet mask information programmed into it using the AB16 and AB17 
buttons.
H3PingIP shows the following information: 
■Port — The UDP Destination Port. 
■Tx — The number of packets transmitted.
■Rx — The number of packets received.
■mS — The delay time, in milliseconds. 
If you ping a device on a subnetwork different than the one on which the 
telephone is located, the delay time is greater.
