SERVICING AND MAITENANCE FOR THE STAL1000 TRANMITTER
Doc.: STAL1000TX-MAN-ENG
Rev.: 1.20
This equipment has been designed and built to operate in a continuous cycle without degradation of its
parameters, however it may require maintenance and / or repair in certain occasions, or in case of failures caused
by abnormal situations in the electrical network, electric discharges on the power lines , signal, data, control and
antenna.
If it is necessary to replace the power fuse (s), always do so for others of the same current.
The only recommended maintenance is the periodic cleaning of the ventilation inlets to allow the passage of clean
air and in the volume necessary to ensure the correct cooling of the equipment.
The printed circuit modules can also be cleaned by blowing clean, dry pressure air over them. Never use solvents
for this operation as this can cause severe damage to the components or permanently disable the plate.
The above cleaning operations are recommended when the equipment operates in environments with a high dust
content in the air.
To carry out any type of maintenance and / or repair operation, the power supply must be disconnected from the
power supply before proceeding to remove the coverings and shields.
HANDLING OF THE MODULES
The modules in this equipment are mostly provided with connectors, so to remove them it is only necessary to
disconnect these connectors and remove the set screw / fixing washer.
Special care must be taken when reinstalling a module, to verify that the connectors are connected in the same
place and position in which they were originally, otherwise damage may occur to them and / or to other parts of
the equipment.
HANDLING OF COMPONENTS
This equipment uses SMD surface mount technology for smaller components such as resistors, capacitors, diodes,
low and medium power transistors and integrated circuits. To remove them always use adequate desoldering tools.
Special care should be taken not to damage the printed circuit board or the metallic holes when removing a
component, since there is a risk that the module will be permanently disabled.
REPLACEMENT OF MODULES
In certain circumstances and in the event of damage caused by non-specified power conditions, adverse
environmental conditions and / or extreme, unpredictable, electric discharges on the power supply, signal, data,
control or antenna, it will be necessary to completely replace the / Damaged modules, pej, power supplies, RF
input stages, CPU board, etc.
