Tips and information for comfortable use

Computer users may complain of eyestrain and headaches after prolonged use.
Users are also at risk of physical injury after long hours of working in front of a
computer. Long work periods, bad posture, poor work habits, stress, inadequate
working conditions, personal health and other factors greatly increase the risk
of physical injury.

Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis,
tenosynovitis or other musculoskeletal disorders. The following symptoms may
appear in the hands, wrists, arms, shoulders, neck or back:

• numbness, or a burning or tingling sensation

• aching, soreness or tenderness

• pain, swelling or throbbing

• stiffness or tightness

• coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort
and/or pain related to computer use, consult a physician immediately and
inform your company's health and safety department.

The following section provides tips for more comfortable computer use.

Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a
footrest, or raising your sitting height to achieve maximum comfort. Observe
the following tips:

• refrain from staying too long in one fixed posture

• avoid slouching forward and/or leaning backward

• stand up and walk around regularly to remove the strain on your leg
muscles

• take short rests to relax your neck and shoulders

• avoid tensing your muscles or shrugging your shoulders

• install the external display, keyboard and mouse properly and within
comfortable reach

• if you view your monitor more than your documents, place the display at
the center of your desk to minimize neck strain

viii

Taking care of your vision

Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on
how to reduce eyestrain.

Eyes

• Rest your eyes frequently.

• Give your eyes regular breaks by looking away from the monitor and
focusing on a distant point.

• Blink frequently to keep your eyes from drying out.

Display

• Keep your display clean.

• Keep your head at a higher level than the top edge of the display so your
eyes point downward when looking at the middle of the display.

• Adjust the display brightness and/or contrast to a comfortable level for
enhanced text readability and graphics clarity.

• Eliminate glare and reflections by:

• placing your display in such a way that the side faces the window or

any light source

• minimizing room light by using drapes, shades or blinds

• using a task light

• changing the display's viewing angle

• using a glare-reduction filter

• using a display visor, such as a piece of cardboard extended from the

display's top front edge

• Avoid adjusting your display to an awkward viewing angle.

• Avoid looking at bright light sources, such as open windows, for extended
periods of time.

Developing good work habits

Develop the following work habits to make your computer use more relaxing
and productive:

• Take short breaks regularly and often.

• Perform some stretching exercises.

• Breathe fresh air as often as possible.

• Exercise regularly and maintain a healthy body.

Warning! We do not recommend using the computer on a couch or
bed. If this is unavoidable, work for only short periods, take breaks
regularly, and do some stretching exercises.

• Handle the processor and the heat sink carefully. Damage to either
may prevent the system from functioning properly.

To upgrade the default processor:

1 Perform the pre-installation instructions described on page 39.

Warning! The heat sink becomes very hot when the system
is on. NEVER touch the assembly with any metal or with
your hands.

2 Remove the air duct. Perform the instructions described in “To

remove the air duct” section on page 47.

3 Remove the heat sink.

(1) Loosen the four captive screws on the heat sink.
(2) Pull the heat sink away from the processor.

(3) Lay down the heat sink in an upright position — with the

thermal patch facing upward. Do not let the thermal patch
touch the work surface.

(4) Use an alcohol prep pad to wipe off the thermal grease from

both the heat sink and the processor socket retention plate.

4 Remove the default processor.

Warning! The processor becomes very hot when the system
is on. Allow it to cool off first before handling.

(1) Release then lift the load lever.
(2) Open the retention plate to expose the socket body.

(3) Grasp the processor by its edges and lift it out of its socket.

(4) Store the old processor inside an anti-static bag.

5 Remove the new processor from its protective packaging.
6 Install the new processor.

(1) Hold the processor by its edges. Make sure the alignment tabs

on the socket fit the two notch located on the edge of the
processor. The pins are keyed in such a way that you cannot
install the processor in the wrong orientation without

bending the pins.
(2) Insert the new processor in the socket.
(3) Close the retention plate.

(4) Engage the load lever back into place.

7 Apply the thermal interface material.

(1) Use an alcohol pad to wipe off the old thermal grease from

both the heat sink and the processor socket retention plate.

(2) Apply a thin layer of an Acer-approved thermal interface

material before installing the heat sink.

Make sure that only a very thin layer is applied so that both
contact surfaces are still visible.

8 Install the heatsink.

Caution! The heat sink has a thermal interface material (TIM) on
the underside. Use caution so that you do not damage the TIM. If
a protective film is installed on the TIM, remove it.

(1) Set the heat sink over the processor, aligning the four captive

screws with the four screw posts surrounding the processor.

(2) Loosely screw in the captive screws on the heat sink corners in

a diagonal manner.

Note: Do not fully tighten one screw before tightening another.

(3) Gradually and equally tighten each captive screw until each is

firmly tightened.

Upgrading the system memory

System memory interface

Acer Altos R720 M2 has twelve DIMM slots. The DIMM slots are color­coded and are labeled DIMM A1, DIMM A2, DIMM B1, DIMM B2, DIMM
C1, DIMM C2, DIMM D1, DIMM D2, DIMM E1, DIMM E2, DIMM F1, and
DIMM F2.

All twelve DIMM slots are shared by two processors. Each processor
controls six DIMM slots. The DIMM slots support three channel DDR3­1333 registered/unbuffered ECC memory modules. For processor 1, it
will be channels A, B, and C and for processor 2, it will be channels D, E,
and F. Each channel is divided into two sockets: Socket 1 and Socket 2.
Socket 1 slots are colored blue and comprised of DIMM slots A1, B1, C1,
D1, E1, and F1 and Socket 2 slots are colored black and comprised of
DIMM slots A2, B2, C2, D2, E2, and F2.

For all memory channel modes, populate the blue slots first, before
populating the black slots. If DIMM slots in Socket 1 are empty, the
DIMM slots in Socket 2 can not be used.

System memory configuration guidelines

• To ensure data integrity, use only Acer-approved 240-pin, DDR3
1333 MHz ECC unbuffered DIMM (UDIMM) or registered DIMM
(RDIMM) modules.

• If you are using a single-processor configuration, you should install
the memory module into DIMM A1 to C2 slots.
The DIMM D1 to DIMM F2 slots are enabled when a second
processor is installed on the mainboard.

• DIMM modules of the same type, size, and manufacturer must be
installed in the same colored DIMM slots.

• Follow the population sequence illustrated in the next section
when installing memory modules.
