CAUTION : When executing Test mode No. 2 RAM CLEAR, be sure to write down the preset memory contents of the
tuner, using a table like the one shown below. Execution of RAM CLEAR will set the memory contents of the
tuner back to the factory preset state which means that all the memories preset by the user will be erased.

Confirmation of Idling Current
1) No signal applied.
2) Non-loaded condition.
3) Aging is not neccessary.
Note
If the measured voltage exceeds 2.5mV, cut the lead wire of R308(L ch)
or R309(R ch) and then check again if each measured value satisfies the
rating.

If R308(L ch) or R309(R ch) have already been cut off and
idling current does not flow, reconnect R308(1k
