Developing good work habits

The following work habits make 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.

Warning

Permanent hearing loss may occur if earphones or

headphones are used at high volume for prolonged periods of

time.

To protect your hearing, follow these instructions.

• Increase the volume gradually until you can hear clearly and

comfortably.

• Do not increase the volume level after your ears have adjusted.

• Do not listen to music at high volumes for extended periods.

• Do not increase the volume to block out noisy surroundings.

• Decrease the volume if you can't hear people speaking near you.
