 Care, Use, and Safety Information

 

Connectors and Ports

Never force a connector into a port. If the connector and port don’t join with 
reasonable ease, they probably don’t match. Make sure that the connector matches the 
port and that you have positioned the connector correctly in relation to the port.

Avoid Hearing Damage

Ergonomics

An adjustable chair that provides firm, comfortable support is best. Adjust the height of 
the chair so your thighs are horizontal and your feet flat on the floor. The back of the 
chair should support your lower back (lumbar region). Follow the manufacturer’s 
instructions for adjusting the backrest to fit your body properly.

Permanent hearing loss may occur if earbuds or headphones are used at 

high volume. You can adapt over time to a higher volume of sound, which may sound 
normal but can be damaging to your hearing. Set your iMac G5 volume to a safe level 
before that happens. If you experience ringing in your ears, reduce the volume or 
discontinue use of earbuds or headphones with your iMac G5.
