Security Cover (Tp-1); Lockable Security Cover (Ts-1); Special Operations - Altair FA-524 Owner's Manual

SECURITY COVER (TP-1)

In some installations it is necessary avoid unwanted manipulations of the crossovers
controls, for which it is available a security cover that avoids the access to the crossovers
controls.
The installation is very easy, by means of two screws provided with the security cover
binds at the front panel, the which has been two threaded holes for this purpose.

LOCKABLE SECURITY COVER (TS-1)

In some installations it is necessary isolate the crossovers controls with high safety that
the which offers the security cover, for the one which it is available a lockable security cover
of easy installation. The lockable security cover is provided with two keys.

6. SPECIAL OPERATIONS

In order to setup some of the crossover possibilities it must be open, removing the eight
screws of their top cover.
NOTE: This type of operations, takes place with the unit open, because of what should be
carried out by qualified technical personal.
WARNING: Before opening the unit, disconnect it of the mains. It is important mark that al-
though the unit is turned off (with the power switch at position 0), if it continues connected to the
mains there is different parts of the unit that are subjected to high tension.
CAUTION: Don't subject the crossover unit to rain or humidity, above all if it is open. If it comes
to produce, disconnect it of the mains and warns a qualified technical service.
How you could note, the different ways are equal, for the one which the localization of a
certain component is easy, since although we locate the another way one, will give us a
comparative position of the component in order to find it in the way that we are interested in.
In each box we will be provided of a main board components amplification that corre-
sponds to the operation that we are explaining, but sometimes for the general localization in
the unit is important to provide the complete main board components picture.
The component are identified by a word and a number. The word indicates the kind of
component to the that we referred (Ejm: R23 is a resistance), and the number their comparative
position in the circuit, beginning for the upper left corner and toward down.
