4.SPECIAL PRECAUTIONS

Warnings, cautions, and notes in this manual give the data that follows:

A WARNING is an operation or maintenance procedure or condition, which, if not obeyed, can cause injury or death.

A CAUTION is an operation or maintenance procedure or condition, which, if not obeyed, can cause damage to the equipment.

A NOTE gives data to make the work easier or gives directions to go to a procedure.

All personnel who operate and do maintenance on the WLU and applicable test equipment must know and obey the safety precautions. The warnings and cautions that follow apply to all parts of this manual:

WARNING: HIGH VOLTAGES MAY BE PRESENT ON SYSTEM INTERCONNECT CABLES. MAKE SURE THAT SYSTEM POWER IS OFF BEFORE YOU DISCONNECT LRU MATING CONNECTORS.

CAUTION: THE SYSTEM CONTAINS ITEMS THAT ARE ELECTROSTATIC DISCHARGE SENSITIVE (ESDS). IF YOU DO NOT OBEY THE NECESSARY CONTROLS, A FAILURE OR UNSATISFACTORY OPERATION OF THE UNIT CAN OCCUR FROM ELECTROSTATIC DISCHARGE. USE APPROVED INDUSTRY PRECAUTIONS TO KEEP THE RISK OF DAMAGE TO A MINIMUM WHEN YOU TOUCH, REMOVE, OR INSERT PARTS OR ASSEMBLIES.

WARNING: THIS EQUIPMENT HAS BEEN TESTED AND FOUND TO COMPLY WITH THE LIMITS FOR A CLASS A DIGITAL DEVICE, PURSUANT TO PART 15 OF THE FCC RULES. THESE LIMITS ARE DESIGNED TO PROVIDE REASONABLE PROTECTION AGAINST HARMFUL INTERFERENCE WHEN THE EQUIPMENT IS OPERATED IN A COMMERCIAL ENVIRONMENT. THIS EQUIPMENT GENERATES, USES, AND CAN RADIATE RADIO FREQUENCY ENERGY AND, IF NOT INSTALLED AND USED IN ACCORDANCE WITH THE INSTRUCTION MANUAL, MAY CAUSE HARMFUL INTERFERENCE TO RADIO COMMUNICATIONS. OPERATION OF THIS EQUIPMENT IN A RESIDENTIAL AREA IS LIKELY TO CAUSE HARMFUL INTERFERENCE IN WHICH CASE THE USER WILL BE REQUIRED TO CORRECT THE INTERFERENCE AT HIS OWN EXPENSE.

WARNING: THIS EQUIPMENT HAS BEEN TESTED AND FOUND TO COMPLY WITH THE LIMITS FOR A CLASS A DIGITAL DEVICE, PURSUANT TO PART 15 OF THE FCC RULES. ACCORDING TO FCC PART 15.203, THE DEVICE AND ANTENNAS MUST BE PROFESSIONALLY INSTALLED ACCORDING TO THESE INSTRUCTIONS OUTLINED IN THIS DOCUMENT. THE ANTENNAS OUTLINED IN THIS DOCUMENT MUST BE USED WHEN INSTALLING THE EQUIPMENT. OTHERWISE, THIS DEVICE MAY CAUSE HARMFUL INTERFERENCE TO RADIO COMMUNICATIONS.

NOTE: THE TESTS IN THE FAULT ISOLATION SECTION SHOULD BE DONE BEFORE THE UNIT IS DISASSEMBLED. THESE TESTS CAN TELL THE CONDITION OF THE WLU OR MOST PROBABLE CAUSE OF ANY MALFUNCTION. SHOULD ANY MALFUNCTION OCCUR, REPAIR AS NECESSARY.
