Scale-Factor LED Replacement
VOLTS/DIV scale-factor LED's (light-emitting diodes) are
pressed into plastic retainer sleeves in front subpanel. LED's
can be removed by pressing them out with a small diameter
blunt instrument.
Refer to Fig. 5-6 when replacing the LED's. Use a low-
wattage soldering iron and apply only enough heat to solder
the LED leads to the etched circuit cable.
