Memory Channel 7 Indicator Erratic
When Memory Channel 7 is selected, the LED may fail to indicate the number 7, although frequency is correctly
recalled and all other operations are normal. Cause is incorrect voltage level at Q16 & Q17, and is related to individual
differences between these IC's. Correction is by changing one resistor value on the control unit.
On the control unit X53-1130-xx, replace R38 from 3.9 Kohm to a 1.8 Kohm resistor (RD14CB2E182J). No adjustments
are required.
This change should be perform only as necessary, and applies to units before serial number 205xxxx.
Installation time for this procedure is ½ hour or less.
