Important Safeguards
For your protection, please read all these instructions regarding your Cobalt Qube 2 and retain for
future reference.
1. Read Instructions
Read and understand all the safety and operating instructions before operating the appliance.
2. Ventilation
The Cobalt Qube 2’s bottom vents and fan opening are provided for ventilation and reliable operation
of the product, and to protect it from overheating. These openings must not be blocked or covered.
This product should not be placed in a built-in installation unless proper ventilation is provided.
3. Lithium Battery
The lithium battery on the system board provides power for the real-time clock and CMOS RAM.
The battery has an estimated useful life expectancy of 5 to 10 years. If your system no longer keeps
accurate time and date settings, it may be time to change the battery. Contact Cobalt for service
information. There are no operator-serviceable parts inside.
Warning:
There is a danger of explosion if the battery is incorrectly
replaced or replaced with the wrong type of battery. Replace only with
the same or equivalent type recommended by the equipment
manufacturer. Dispose of used batteries according to manufacturer’s
instructions.
Avertissement :

Caution:
The power-supply cord is used as the main disconnect
device. Ensure that the socket outlet is located or installed near the
equipment and is easily accessible.
!
Attention :
Le cordon d’alimentation sert d’interrupteur général. La
prise de courant doit être située ou installée à proximité du matériel et
offrir un accès facile.
!
Achtung:

5. Electrical Shock
To reduce the risk of electrical shock, do not disassemble this product. Take it to a qualified service
person when service or repair work is required. Opening or removing covers may expose you to
dangerous voltage or other risks. Incorrect reassembly can cause electric shock when this product is
subsequently used.
6. Browsers
Both Netscape Navigator® and Microsoft® Internet Explorer have bugs that can cause intermittent,
unexplained failures. When using a Web browser to interact with your Cobalt Qube 2, you may
occasionally experience a browser failure. Released product versions of the browsers are usually
more reliable than beta versions and later versions typically work the most reliably. A browser
program failure, although annoying, does not adversely affect your Cobalt Qube 2’s data.
