 Setting up Parameters

Switching Modes: DTV is in the operation mode when the power is switched on, displaying PV and SV. Press

for more than 3 seconds to enter the

initial setting mode. Press

for less than 3 seconds in the operation mode to enter the regulation mode. Press once in the regulation or initial setting

mode to return to the operation mode.

Selecting parameters: In the operation, regulation or initial setting mode, press

to select parameters for setup.

Setting up number parameters: Find the parameters to be set up or modified. Use

to modify the settings. Press to move to the desired digit to

be modified and the digit will flash. Press

to complete and save the setting.

Setting up non-number parameters: Find the parameter to be set up or modified and use

to modify the setting. The parameter will flash at this time.

Press

to complete and save the setting.
