    - Batteries for remote control (R6, “AA”, UM-3))........2 pcs. Note: These are available on sales route. 2. Handling Precautions for Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
