Power save setting OFF 1 to 29 Indicates “SLP” after the set time has elapsed. Indicates “---” after 30 minutes. NOTE Check the power-save operation according to the procedure in Section 2-5: "Iron Holder Check “ 2-4 Voltage Application Check (FX-951/FH-200)
Page 11
If a faulty portion is found: Correct soldering. If a pattern coming off is found: Replace the whole P.W.B. CAUTION If a fault is not found visually, replace the whole P.W.B. (for control/connector). 2-4 Voltage Application Check (FX-951/FH-200)
If the resistance value is ∞: The connecting cable is broken. Replace the connecting cable with a new one. Check the resistance values in the 2 sections A and B. 2-5 Iron holder check (FX-951/FH-200)
