Power Saver
As part of the ENERGY STAR program, this product is designed with an energy-saving mode called Power Saver. The Power Saver
Mode is equivalent to the EPA Sleep Mode. The Power Saver Mode saves energy by lowering power consumption during extended
periods of inactivity. The Power Saver Mode is automatically engaged after this product is not used for a specified period of time, called
the Power Saver Timeout. The factory default Power Saver Timeout for this product is 30 minutes.
By using the configuration menus, the Power Saver Timeout can be modified between 1 minute and 240 minutes. Setting the Power
Saver Timeout to a low value reduces energy consumption, but may increase the response time of the product. Setting the Power Saver
Timeout to a high value maintains a fast response, but uses more energy.

Total energy usage

It is sometimes helpful to calculate the total product energy usage. Since power consumption claims are provided in power units of
Watts, the power consumption should be multiplied by the time the product spends in each mode in order to calculate energy usage.
The total product energy usage is the sum of each mode's energy usage.
