Operating Precautions
Attaching the Strap
CAUTION
Attach the strap securely at 2 locations of the instrument. If insecurely attached, the
instrument may fall and be damaged when carrying.
Using SD Memory Cards
CAUTION
• Do not remove a card while data is being written to it. Doing so may damage the card.
See “10.10 Removing SD Memory Card during Recording” (p. 127).
• Exercise care when using such products because static electricity could damage the SD
card or cause malfunction of the instrument.
IMPORTANT
•
Format the card with the instrument. Using a computer to format the card may reduce the
card’s performance.
See “10.9 Formatting SD Memory Card (Deleting All Files)” (p. 126).
• No compensation is available for loss of data stored on the SD memory card, regardless of the
content or cause of damage or loss. Be sure to back up any important data stored on an SD
memory card.
• Observe the following to avoid corruption or loss of stored data:
• Do not touch the electrical contacts on the card or inside the insertion slot with your skin or
metallic objects.
• While writing or reading data, avoid vibration or shock, and do not turn the power off or
remove the card from the instrument.
• Before formatting (initializing) a card, conrm that it contains no important information (les).
• Do not bend or drop the card, or otherwise subject it to intense shock.
• The operating lifetime of the SD memory card is limited by its ash memory. After long-term or frequent
usage, data reading and writing capabilities will be degraded. In that case, replace the card with a new one.
• If you are unable to write data to an SD memory card, manipulate folders and les, or format the card, check
the position of the write-protect lock and disengage it if necessary.
The connector of the SD memory card is used to judge whether the card is write-protected.
If the write-protected lock is in an intermediate position, the determination of whether the card is write-
protected will depend on the connector. For example, even if the instrument determines that the card is
not write-protected and allows data to be written to it, a computer may determine that it is write-protected,
preventing data from being written to it.
