supplied by Comdial and which are not compatible with the Product or which are of inferior quality, design or performance, or the Product, or
any part(s) or component(s) thereof, have been improperly handled, misused, abused, altered, tampered with, accidentally damaged, or damaged
or malfunction or fail to function as a result of causes beyond Comdial’s reasonable control, including acts of God such as fire, flood, water, or
lightning or other incidence of excessive or insufficient voltage or failure to follow instructions. Repair, wiring, or alteration of the Product
other than as specifically authorized by Comdial or its authorized repair agent is prohibited and will void this warranty. This warranty does not

Limitation Of Liability
WITHOUT EXPANDING UPON THE FOREGOING WARRANTY, THE MAXIMUM LIABILITY OF COMDIAL UNDER ANY
WARRANTY, STATUTORY, EXPRESS OR IMPLIED, IS LIMITED TO THE PURCHASE PRICE OF THE PRODUCT. COMDIAL
SHALL HAVE NO RESPONSIBILITY FOR DAMAGE TO PROPERTY OR ANY OTHER LOSS OR INJURY, INCLUDING
CONSEQUENTIAL, INCIDENTAL, OR INDIRECT DAMAGES, SUCH AS LOSS OF PROFITS OR LOSS OF BUSINESS
INFORMATION, DAMAGES DUE TO BUSINESS INTERRUPTION OR ANY OTHER PECUNIARY LOSS, EVEN IF COMDIAL HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR PUNITIVE DAMAGES, RESULTING FROM THE PURCHASE,
POSSESSION, INSTALLATION, OPERATION, REPAIR, USE OF OF OR INABILITY TO USE, THE PRODUCT, OR THE
UNAUTHORIZED OR THE FRAUDULENT USE OF, OR UNACCOUNTED FOR ACCESS TO, THE PRODUCT, ALL SUCH CLAIMS
BEING HEREBY EXPRESSLY WAIVED. THE PURCHASER’S EXCLUSIVE WARRANTY AND REMEDY SHALL BE ONLY AS
STATED HEREIN.
This warranty gives you specific legal rights and you may also have other rights which may vary from state to state.  Some states do not allow
limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitations
may not apply to you.  If the Magnuson Moss Act should be held to apply to the sale of the Product by a court of competent jurisdiction, the
implied warranty of fitness for a particular purpose shall extend for one year from the date of manufacture. No Comdial dealer nor any other
person or entity other than Comdial may extend or modify this warranty, and no such modification or extension shall be effective unless it is in
writing.

							2.12.1 Making Modular Jack Data Connections
Modular jack connections are wiring connections from a station to a modular (wall) jack.
The system provides two serial data ports on the J0408:
·Connect a video display terminal (VDT), Tracker, or VoiceMail to COM 1.
·Connect a serial data printer or Caller ID to COM 2.
The system provides four serial data ports on the J0816 and J1632:
·Connect a video display terminal (VDT) to COM 1.
·Connect a serial data printer or Caller ID to COM 2.
·Connect VoiceMail to COM 3.
·Connect Tracker to COM4.
NOTE: The distance between a data device and the common equipment can be up to 500 feet
in a quiet electrical environment. Some sites may require shielded cable for long
runs. For longer distances, you must install limited distance modems to relay the data
communications between the common equipment and a data device.
When preparing a cable for connection to a data device, refer to the manufacturer’s manual for
the equipment being interfaced and make the following wiring connections:
·Wire the common equipment RD (data from device to common equipment) connection to
the device TD (transmit data) connection.
·Wire the common equipment TD (data to device from common equipment) connection to
the device RD (receive data) connection.
·Wire the common equipment SG (signal ground) connection to the device SG (signal
ground) connection.
·If required for proper operation, wire the common equipment CTS (clear-to-send status
from device to common equipment) connection to the device RTS (request-to-send)
connection.
NOTE: The common equipment requires a positive voltage, with respect to signal ground, in
order to send data.
