the same three wire grounded connection. It is important that the

blades of the equipment’s plug be able to fully insert into the mating

receptacle. 

Never remove the round grounding pin on the plug in

an attempt to mate to a two wire ungrounded receptacle:

 use a

grounding adaptor with the grounding tab or wire suitably connected

to earth ground.

11. NON-USE PERIODS

During periods of extended non-use, the power cord should be

unplugged from the power source.

12. CLEANING

The equipment should be cleaned only as detailed in the operating

instructions.

13. OBJECT AND LIQUID ENTRY

Care should be taken so that objects and/or liquids, such as

cleaning fluids or beverages, are not spilled into the enclosure of

the equipment.

14. DAMAGE REQUIRING SERVICE

Hafler equipment should be serviced by qualified service personnel

when:

a. 

The power supply cord or plug has been damaged, or

b.

 Objects have fallen, or liquid has been spilled into the

equipment, or

c.

 The equipment has been exposed to rain, or

d.

 The equipment does not appear to operate normally or

exhibits a marked change in performance, or

e.

 The equipment has been dropped, or the enclosure has

been damaged.

15. SERVICING

The user should not attempt to service the equipment beyond that

which is described in the operating instructions. All other service

should be referred to qualified service personnel.

16. CARTS AND STANDS

The equipment should be used with carts or stands only of sufficient

strength and stability for the use intended.

An equipment and cart combination should be moved with care.

Quick stops and starts, excessive force, and uneven surfaces may

cause the equipment and cart combination to topple.

17. NO USER ACCESSIBLE PARTS

The P3100 has no user accessible parts inside the device and should 

only be serviced by a qualified technician.

1. READ INSTRUCTIONS

All the safety and operating instructions of your Hafler equipment

should be read before power is applied to the equipment.

2. RETAIN OWNER’S MANUAL

These safety and operating instructions should be retained for

future reference.

3. HEED WARNINGS

All warnings on the equipment and in the operating instructions

are important and should be followed.

4. FOLLOW INSTRUCTIONS

All operating and use instructions are important and should be

followed.

5. HEAT

The equipment should be kept away from areas of high temperature,

i.e., heater vents, radiators, stoves/ovens, fireplaces, etc.

6. VENTILATION

The equipment should be used in an area suitable for proper

ventilation. Care should be taken not to impede airflow in and

around the cabinet. Do not mount on a carpeted shelf or in a

sealed enclosure. Allow for proper clearance above the equipment.

7. WATER AND MOISTURE

The equipment should not be used in or around water, such as a

bathtub, sink, or swimming area. Also, the equipment should not

be used in areas prone to flooding, such as a basement.

8. POWER SOURCES

The equipment should be connected only to a power source of

the same voltage and frequency as that listed on the rear panel

above the power cord entry point.

9. POWER CORD PROTECTION

Power cords should be arranged so they do not interfere with the

movement of objects in the room: people, fan blades, utility carts,

etc. Also, care should be taken that the cord is not pinched or cut,

and placed so it is not in danger of being pinched or cut, as in

under a rug, around a tight corner, etc.

10. POWER CORD GROUNDING

The power supply cord is of a three wire grounded type, designed

to reduce the risk of electric shock sustained from a live cabinet.

It is assumed to be of suitable length for most uses of the

equipment. The use of extension cords and power strips is

discouraged unless they are of suitable rating to deliver the

required total current for safe operation of all connected equipment.

Furthermore, extension cords or power strips must provide
