· micro SDHC card (& SD card adapter) preparation and current firmware version confirmation
1. Prepare a micro SDHC card (Capacity: 2GB ~ 32GB, preformatted
with FAT32/exFAT).
* CAUTION
Since the HP-A4BL does not recognize a micro SDXC card (larger
than 64GB), use a micro SDHC card (capacity: 2GB ~ 32GB).
2. Insert the micro SDHC card into the micro SD card slot on the HP-
A4BL rear panel.
* CAUTION
Do not power on the HP-A4BL before inserting the SDHC card
into the slot.
3. After connecting the AC adapter bundled in the HP-A4BL
package to the [DC IN] port on the HP-A4BL rear panel,
power on the HP-A4BL by turning the [POWER] switch
/ Volume knob to the right. The HP-A4BL power LED
turns on in green and the Fs: 44.1kHz LED flashes in red.
The HP-A4BL recognizes the micro SDHC card inserted
into the micro SD card slot on the rear panel and creates
the "HPA4BL_VER.txt" file in which the firmware ver-
sion number is written in the micro SDHC card root di-
rectory.
4. After powering off the HP-A4BL by turning the [POWER]
switch / Volume knob to the left, remove the micro SDHC
card from the HP-A4BL. After fitting it into the SD card
adapter, insert it into the Windows PC/Macintosh SD card
slot. Next, open up the "HPA4BL_VER.txt" file in the
micro SDHC card root directory and check the HP-A4BL current firmware version "VX.XX" (V1.01 in the lower
right example).
