3. Pressing the adjacent soft function buttons to the displayed ISVPL values selects or deselects the param-
eters from the rotary encoder.
Selected ISVPL value is highlighted (inverse video)
De-selected ISVPL value is not highlighted (standard video)
4. Select which PLM channels are to be assigned to the rotary encoder, then turn the rotary encoder to
adjust the parameter values as required.
It is also possible to use the multi-select function to alter multiple channel parameters even if the values
differ between each channel. Turning the rotary encoder simply adjusts each parameter (by +/- 0.1 V in the
case of the ISVPL screen). When in Meter mode, the rotary encoder allows the user to change between the
four different meter views.
5. The rotary encoder also scrolls thru the different meter views while at HOME.

9.9 Exit Button

The EXIT key is used while navigating the menu system in MENU mode, and takes the display
back to a previous screen ("up one level" in the menu tree).
In METER mode, pressing the EXIT key will always return the display to the HOME view.

9.10 Soft-function buttons

Eight silicon rubber buttons are set adjacent to the display in two groups of four. These buttons
are unlabelled because their functions change according to the on-screen page currently displayed.
