Important Notes

• For other SD memory cards, we recommend using an SDXC card whose capacity is 64 GB or larger.
  Before actual use, carry out a speed test on the P-20HD, and use a card whose speed is 15 MB/s or higher.
• Operation using a microSD card is not supported.
• When using an SD memory card, be sure to format it on the P-20HD.
  SD memory cards formatted on devices other than the P-20HD might fail to function correctly.
• Never insert or eject an SD memory card while the unit's power is on. Doing so risks loss of data on the SD memory card.
• We recommend backing up SD memory cards to a computer to safeguard against accidents.
