CHAPTER 4 MAINTENANCE AND TROUBLESHOOTING

Maintenance of the Unity 4600 is limited to keeping the chassis clean and ensuring

that all the cables remain firmly connected. Occasionally wipe the exterior with a soft,

damp cloth to remove any accumulated dust and dirt, and check that the cables are

securely attached.

The Unity 4600 incorporates security labels over some of the screws. There are no

user-serviceable components within the U4600. 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 Ser-

vice.

This section is not intended as an exhaustive list of all possible situations, but a list of

the most common installation problems. Please contact us (see Chapter 5, Customer

Service), with any problems you cannot resolve independently.

If you are experiencing any difficulties, first check the LED indicators on the U4600

front panel. See Table 3.2: Front-Panel LED Indicator Descriptions on page 29 for

details about the LED indicators. Note that during typical operation, the green CAR-

RIER, TRANSPORT, COMPEL, SERVICES, and AUTH LEDS should be on.

If the unit provides no output and neither the LCD nor any LEDs are lit, there is either

a loss of AC power or the internal power supply has failed. 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.

c. If both checks a. and b. are okay, contact Customer Service (see Chapter 5)

before returning the unit for service.

IRD at the selected RF port. To rule these out, verify that the LNB (and any
