OPERATION MANUAL NAV-402AP-3 SAFETY FIRST: TO ALL OPERATIONS PERSO NNEL REFER ALL SERVICING OF UNIT TO QUALIFIED TECHNICAL PERSONNEL. this unit contains no operator serviceable parts. WARNING: USING THIS EQUIPMENT IN A MANNER NOT SPECIFIED BY THE ACCOMPANYING DOCUMENTATION MAY IMPAIR THE SAFETY PROTECTION PROVIDED BY THE EQUIPMENT. CASE, COVER OR PANEL REMOVAL Removing the Chassis Assembly from the Case Assembly exposes the operator to electrical hazards that can result in electrical shock or equipment damage. Do not operate this Test Set with the Chassis Assembly removed from the Case Assembly. SAFETY IDENTIFICATION IN TECHNICAL MANUAL This manual uses the following terms to draw attention to possible safety hazards, that may exist when operating this equipment. CAUTION: THIS TERM IDENTIFIES CONDITIONS OR ACTIVITIES THAT, IF IGNORED, CAN RESULT IN EQUIPMENT OR PROPERTY DAMAGE (E.G., FIRE). WARNING: THIS TERM IDENTIFIES CONDITIONS OR ACTIVITIES THAT, IF IGNORED, CAN RESULT IN PERSONAL INJURY OR DEATH. SAFETY SYMBOLS IN MANUALS AND ON UNITS CAUTION: THIS SYMBOL REFERS TO SPECIFIC CAUTIONS REPRESENTED ON THE UNIT AND CLARIFIED IN THE TEXT. AC OR DC TERMINAL: TERMINAL THAT MAY SUPPLY OR BE SUPPLIED WITH AC OR DC VOLTAGE. DC TERMINAL: TERMINAL THAT MAY SUPPLY OR BE SUPPLIED WITH DC VOLTAGE. AC TERMINAL: TERMINAL THAT MAY SUPPLY OR BE SUPPLIED WITH AC OR ALTERNATING VOLTAGE. SWITCH ON/OFF (PUSH-PUSH): POWER TO THE DEVICE IS CONNECTED ON OR DISCONNECTED OFF. EQUIPMENT GROUNDING PRECAUTION Improper grounding of equipment can result in electrical shock. USE OF PROBES Check specifications for the maximum voltage, current and power ratings of any connector on the Test Set before connecting it with a probe from a terminal device. Be sure the terminal device performs within these specifications before using it for measurement, to prevent electrical shock or damage to the equipment. POWER CORDS Power cords must not be frayed, broken nor expose bare wiring when operating this equipment. USE RECOMMENDED FUSES ONLY Use only fuses specifically recommended for the equipment at the specified current and voltage ratings. INTERNAL BATTERY This unit contains a Sealed-Lead Battery, serviceable only by a qualified technician. CAUTION: SIGNAL GENERATORS CAN BE A SOURCE OF ELECTROMAGNETIC INTERFERENCE (EMI) TO COMMUNICATION RECEIVERS. SOME TRANSMITTED SIGNALS CAN CAUSE DISRUPTION AND INTERFERENCE TO COMMUNICATION SERVICES OUT TO A DISTANCE OF SEVERAL MILES. USERS OF THIS EQUIPMENT SHOULD SCRUTINIZE ANY OPERATION THAT RESULTS IN RADIATION OF A SIGNAL (DIRECTLY OR INDIRECTLY) AND SHOULD TAKE NECESSARY PRECAUTIONS TO AVOID POTENTIAL COMMUNICATION INTERFERENCE PROBLEMS.
