Chapter 4 Maintenance and Troubleshooting
4.1 Maintenance
Maintenance of the DTV 720 is limited to keeping the chassis clean and ensuring that
cables remain firmly connected. Occasionally wipe the exterior with a soft, damp cloth to
remove any accumulated dust and dirt and check that cables are securely attached.
The DTV 720 incorporates security labels over some of the screws. There are no user-ser-
viceable components within the DTV 720. Tampering with the security labels or opening
the unit will void your warranty. If you have any questions, contact Wegener’s Customer
Service Department at the address or numbers listed under Customer Service.
4.2 General Troubleshooting
This section is not an intended as an exhaustive list of all possible situations. Please con-
tact us as directed in Chapter 5 Customer Service on page47, with any problems you
cannot resolve independently.
If you are experiencing any difficulties, first check the LCD and LED indicators on the DTV
720 to determine if any warnings or alarms are active. See Table 6: LED Indicator
Descriptions on page 27 for descriptions of LED states. If operating over the Ethernet
interface, check the Control and Status tab on your browser for Warning messages.
In the following sections, LEDs are illustrated as black (off) or white (on) to represent
actual LED appearance.
No Functions
at All
If the unit is not functioning at all and neither the LCD nor any LEDs are active, there may
be a loss of ac power. Do the following:
a. Check that ac power cord is firmly connected at both ends.
b. Check that your ac power source is supplying ac power.
