3.2 Compensation Adjustment Procedure
 Press the SEL button once to enter the adjustment-mode
(without first hitting SEL button the ▲/▼ buttons are
inactive).
 In adjustment-mode, all 3 LED’s on the unit will be turned
on.
 The ▲/▼ buttons can now be used to adjust the high
frequency (HF) compensation up or down until the video
no longer looks smeared (see figure below).
 Pressing both the ▲/▼ buttons together resets the
current adjustment back to zero, so that the user may
start over.
 To exit the adjustment mode at any time, press the SEL
button (the unit also has a built-in timeout to exit this
mode).
