• DC 3 V in DC IN jack (J402)

Procedure :
1. Connect a digital voltmeter to the test points TP (VCPU) and

TP402 (GND).

2. Supply DC 3 V in DC IN jack (J402).
3. Adjust the RV401 so that the reading of the digital voltmeter

becomes 1.9V+0.05/-0.0V.

• Adjustment value : VCPU = 1.9V V (1.90V to 1.95V)
