CF-3600A/3800A Frequently Asked Questions

■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 main unit. It charges when the AC adapter is connected.
• Purpose and usage time of the battery pack
  The battery pack is for instant power outage measures. Therefore, the usage time of the battery pack alone is about 20 minutes. If the capacity of the battery pack is insufficient, the front panel of the CF-3600 and the low battery indicator (LOW BAT) will light up in red.
• Note about the battery pack
  If not used for a long time, please remove the battery pack from the main unit and store it. Internal discharge will progress, leading to a fully discharged state, which shortens the lifespan of the battery pack.
  
  The battery pack is a consumable item. If it deteriorates, it can be replaced by the customer. Please refer to the "Battery Pack Replacement Procedure" in the instruction manual for the replacement steps. To prevent malfunction, misoperation, and hazards, always use the battery pack specified by our company.
