4.1 Maintenance
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

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

before returning the unit for service.
