In areas with unstable power grids (mains) all repeaters must be installed with a voltage regulator ensuring a constant voltage level at the repeater power input. A maxi mum voltage d eviation should remain within the input ran ge to the repeaters for warranty purposes.

All antennas must be installed with lightening protection. Damage to inter nal modules, as a result of lightening is not covered by the warranty.

All specifications are subject to change without prior notice.

3. Safety Inst r uctions and Warnings

3.1. Personnel Safety

Before installing or replacing any equipment, the entire manual should be read and understood. The user ne eds to supply the appropriate AC power to the Repeater. Inc orrect AC p ower settings can damage the re pea ter and may cause injury to the user.

Throughout this manual, there are "Caution" warnings, "Caution" calls attention to a procedure or prac tice, which, if ignored, may result in injury or damage to the system or system component or even the user. Do not perform any procedure preceded by a "Caution" until the described conditions are fully understood and met.

3.2. Equipment Safety

When installing, replacing or using this product, observe all safety precautions during handling and operation. Failure to comply with the following general s afety precautions and with spec ific precautions described elsewhere in this manual violates the safety standards of the design, manufacture, and intended use of this product. Shyam Telecom Limited assumes no liability for the customer's failure to comply with these precautions. This entire manual should be read and understood before operating or maintaining the repeater system.

It calls attent ion to a procedure or practice whi ch, if not followed, may res ult in personal injury, damage to the system or damage to individual components. Do not perform any procedure preceded by a

CAUTION until described conditions are fully understood and met.
