15.3 Replacing the Built-in Battery Pack
■ Replacing procedure of the built-in battery pack
IMPORTANT
• Follow the directions given below and exercise care when replacing the built-in battery
pack not to break or damage the PCB or cable.
NOTE
• The built-in battery pack replacement should be done where there is as little dust and
other shop contamination as possible. In addition, exercise care so that dust or oil mist
does not penetrate the display unit. During the built-in battery pack replacement, the
circuit board in the SJ-210 is temporarily exposed. A malfunction may result if dust or
shop contamination soils the circuit board.
1 Separate the drive/detector unit from the display unit.
2 Remove the two tapping screws at the bottom of the display unit using a Phillips
screwdriver.
Do not lose the tapping screws and drive/detector unit retaining plate during this
operation.
