■Battery pack for CF-3600

• About the battery pack
  The battery (lithium-ion rechargeable battery) is included as standard. The charger is built into the unit. Charging begins when the AC adapter is connected.
• Battery pack: intended use and usage time
  The battery pack is for protection against momentary power outages. Therefore, the battery pack alone can only be used for approximately 20 minutes. When the battery pack's capacity is low, the low battery indicator (LOW BAT) on the front panel of the CF-3600 will light up red.
• Notes regarding the battery pack
  If you will not be using the device for an extended period, remove the battery pack from the main unit and store it separately. Internal discharge will progress, leading to a complete discharge and shortening the battery pack's lifespan.
  
  The battery pack is a consumable item. If it deteriorates, you can replace it yourself. Please refer to the "Battery Pack Replacement Procedure" in the instruction manual for replacement instructions.
