SAFETY FIRST - TO ALL OPERATIONS PERSONNEL (cont)
Equipment Grounding Protection
Improper grounding of equipment can result in electrical shock. Refer to Chapter 2, Installation for
information on properly grounding the Test Set.
Use of Probes
Check the 3900 Platform 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 be in good working condition. Power cords must not be frayed or 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. Refer to Chapter 2, Installation
and the 3900 Platform Specifications for information on
fuse requirements and specifications.
Internal Battery
This unit contains a Lithium Ion Battery, serviceable only by a qualified technician.
Signal Generators can be a source of Electromagnetic Interference (EMI) to communication
receivers. Some transmitted signals can cause disruption and interference to communication
service out to a distance of several miles. User 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.
Electrical Hazards (AC supply voltage)
This equipment is provided with a protective grounding lead that conforms with IEC Safety Class I.
To maintain this protection the supply lead must always be connected to the source of supply via a
socket with a grounded contact.
Be aware that the supply filter contains capacitors that may remain charged after the equipment is
disconnected from the supply. Although the stored energy is within the approved safety
requirements, a slight shock may be felt if the plug pins are touched immediately after removal.
Do not remove instrument covers as this may result in personal injury. There are no user-
serviceable parts inside.
Refer all servicing to qualified personnel. See the list of Aeroflex offices on the back of the manual.
Fuses
Note that the internal supply fuse is in series with the live conductor of the supply lead. If
connection is made to a 2-pin unpolarized supply socket, it is possible for the fuse to become
transposed to the neutral conductor, in which case, parts of the equipment could remain at
supply potential even after the fuse has ruptured.
