1.1 BEFORE ASSEMBLY AND DISASSEMBLY
1.1.1 Precautions
1. Be sure to remove the power supply unit prior to mount-
ing and soldering of parts.
2. When connecting and disconnecting the connectors, be
careful not to damage the wire.
3. When replacing chip parts (especially IC parts), desolder
completely first (to prevent peeling of the pattern).
4. Tighten screws properly during the procedures.
Unless specified otherwise, tighten screws at a torque
of 0.1N•m (1.0 kgf•cm).
CAUTION!!
RISK OF ELECTRIC SHOCK
When disassembling the unit, electric hazards may
occur in some cases if the capacitor for strobe
emission (STROBE board C6512) has been charged.
Therefore be also very careful when performing repairs
and inspections.
It is recommended that operations be carried out after
waiting for more than ten minutes with the power
supply removed or after discharging the capacitor
forcibly.
Discharge the capacitor according to <NOTE 2> on
Page 1-3.
C6512 is located behind the STROBE board.
