Question about Remington MicroScreen Intercept M-8221 Electric Shaver
How do I change the battery on my Remington M8221 shaver?
• Thoroughly clean the razor cutter area
• Pull off (straight out) cutters and lay aside
• Release spring clips and remove
• Gently pry up and remove rubber boot
• Pry case open starting at cutter end and bending up toward connector end
• Thoroughly clean razor interior area (blow out)
• Pull up motor and remove black oscillator bars
• Pry up the circuit board by releasing the cutter-end catch using a small tool to push it in while prying gently up on the cutter-end of the board and bending up
• Clean the board and turn it over
• Note battery polarity and mark on board if not present already
• Unsolder the battery tabs using unsolder braid. Be careful not to short the electrical circuitry as the batteries are electrically LIVE at this point.
• Remove the old batteries and fully clean off the circuit board solder-pads using unsolder braid.
• Mark the installation date on the new batteries in a place where it will be visible
• Install new batteries, making sure the polarity is correct (cut the tabs to a correct length if they extend too far through the circuit board)
• Solder the battery tabs being careful not to short the electrical circuitry as the batteries are electrically LIVE at this point
• Re-install the circuit board and other parts following the procedure in the reverse order (be sure to put a soft rubber pad over the motor to hold it firmly in place when the upper case half is snapped in place)
• Before installing the metal retaining clips be sure that the rubber boot is fully free and not pinched between the case halves
• Finalize the assembly by reinstalling the cutters and screen
