This signal indicates that keyboard initialization has failed. Check the keyboard
connection to the terminal back panel.
It is possible for the keyboard to function correctly, despite this double-beep
signal. As a quick test of keyboard operation, enter set-up mode by pressing the
<Ctrl><Alt><Esc> keys simultaneously. If set-up mode is working, you can
ignore the double beep signal and use the terminal normally.
 - ETHERNET CONNECTION GREEN INDICATOR DOES NOT LIGHT
This indicator is the green LED located on the left side of the network connector
on the terminal back panel.
Failure to light when the terminal is switched on may be due to any of the
following:
- The Ethernet cable is disconnected at the far end,
- The device (host or hub), to which the network cable is connected, is not
switched on,
- There is a fault on the Ethernet cable or the cable is wired with incorrect
pin assignments.
 - THE CONNECTED PRINTER DOES NOT WORK
First check that the cable pin assignment is correct.
Test the printer in local mode by selecting the [ASCII TEST] button within the
auxiliary port dialog box. (If ASCII format is not supported by the printer, the
banner won't be displayed.)
