Recording media
This system uses SD/SDHC cards for recording.
o In this manual, SD/SDHC cards are referred to as "SD cards".
o Prepare recording media that has been formatted by the
WP-120A (page 68).
o Do not use a computer to delete, move or otherwise alter
data recorded on an SD card. Doing so could cause the
WP-120A to become unable to properly record data.
We recommend the following SD cards.
o SanDisk Ultra PLUS 32 GB
o SanDisk Extreme 32 GB
Insertion and removal
Always insert and remove SD cards when they are not being
accessed.
Never remove an SD card when the unit is operating (includ-
ing when recording). Doing so could cause recording to fail
or recorded data to be lost, for example. Moreover, doing so
could also damage the unit.
Inserting SD cards
1
Open the recording media slot cover on the bot-
tom of the front of the unit.
2
Push the SD card all the way into the SD card slot
on the right side of the opening.
o The SD card has a front end that must be inserted
first. Insert the card with the correct orientation.
Forcing a card into the card slot could damage this
unit.
o A clicking sound can be heard when the card is
pushed all the way in.
3
Close the recording media slot cover.
Removing SD cards
1
Open the recording media slot cover.
2
Push the SD card in gently.
The SD card will come out part way.
3
Pull the SD card out by hand.
4
Close the recording media slot cover.
SD card write-protection switches
SD cards have write-protection switches.
Writing prohibited
Locked
Write-protection switch
Writing data can be prohibited by moving
the switch to the LOCK position.
o Slide the write-protection switch to
one direction completely.
o To use an SD card for recording or to erase recording data
on it or format it, unlock the write-protection.
ATTENTION
When using an SD card with a capacity of 2 GB, FAT file sys-
tem restrictions limit the number of files to 127. Even when
using a card with a larger capacity, we recommend keeping a
maximum of about 1000 data files because processing speed
becomes slower as the number of files increases.
