Sleep Mode
This product is designed with an energy-saving mode called Sleep Mode. The Sleep Mode saves energy by lowering
power consumption during extended periods of inactivity. The Sleep Mode is automatically engaged after this product
is not used for a specified period of time, called the Sleep Mode Timeout.
Factory default Sleep Mode Timeout for this product (in minutes): 20
By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and 240 minutes. Setting
the Sleep Mode Timeout to a low value reduces energy consumption, but may increase the response time of the product.
Setting the Sleep Mode Timeout to a high value maintains a fast response, but uses more energy.

Off mode
If this product has an off mode which still consumes a small amount of power, then to completely stop product power
consumption, disconnect the power supply cord from the electrical outlet.
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.
