Power Saver
This product is designed with an energy‑saving mode called Power Saver. 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.
Factory default Sleep Mode Timeout for this product—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.
O mode
If this product has an o mode which still consumes a small amount of power, then to completely stop product
power consumption, disconnect the power supply cord from the wall outlet.
