Motorola Solutions Inc. 99FT4100 Manual De Usuario

Periodic visual inspection and cleaning is recommended.

Check that the external surfaces of the SLR 1000 Series Repeater are clean, and that all external
controls and connections are in order. It is not recommended to inspect the interior electronic circuitry.

The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the SLR 1000 Repeater. External surfaces include
the top cover and repeater enclosure.

Periodically clean smudges and grime from exterior enclosure. Use a soft, non-abrasive cloth
moistened in a 0.5% solution of mild dishwashing detergent and water solution. Rinse the surface
using a second cloth moistened in clean water, and clean any dirt or debris from the heatsink fins.

The only factory recommended liquid for cleaning the printed circuit boards and their components is
isopropyl alcohol (100% by volume).

Complementary metal-oxide semiconductor (CMOS) and laterally diffused metal-oxide semiconductor
(LDMOS) devices are used in this family of stations, and are susceptible to damage by electrostatic or
high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later.
Therefore, special precautions must be taken to prevent device damage during disassembly,
troubleshooting, and repair.

Handling precautions are mandatory for CMOS/LDMOS circuits and are especially important in low
humidity conditions.

DO NOT attempt to disassemble the repeater without first referring to the following CAUTION
statement.
