SERVICE DEFAULT MODE (SDM)
1. The Service Default Mode is a technical aid for the service technician. It establishes a fixed, repeatable
setting of controls to allow measurements to be made. On screen display is kept at a minimum to reduce
the cluttering of waveforms with unwanted information. The Service Default Mode (SDM) is used when
taking voltages and waveforms, and displays error codes.
2. To enter the Service Default Mode, press the following key sequence on the remote control transmitter:
0-6-2-5-9-6-Menu
Do not allow the display to time out between entries while keying the sequence.
When Service Default Mode is entered, the text "SDM" will be displayed in the upper right corner of the
screen.
3. When the unit is operating in Service Default Mode, all normal on-screen displays are suppressed and
replaced by a special service display. A sample SDM display is shown below.
ERR 14 0 0
4. Press the Status button to display the error buffer. Pressing Status again will hide the error buffer.
5. When the Menu button is pressed on the remote control while in SDM, the software will switch to a Virtual
Customer Mode, with the text "SDM" still displayed in the top-right corner of the screen. In this mode, all
customer menu adjustments to the set can be made. From the Virtual Customer Mode, press the Menu
button to return to the SDM Menu.
6. To exit the Service Default Mode and erase the error codes, turn the unit off with the Power button on the
remote control or the local keyboard, then unplug the ac cord.
7. To exit the Service Default Mode and save the error codes, unplug the ac cord to turn off the set. When the
set is turned on again, the Service Default Mode will still be active.
