Write-protecting the memory card:

The memory card is provided with a writeprotect switch for preventing inadvertent writing. Turn on the write-protect switch

(to set the write-protect) except when

storing the data into the memory card.

To set the write-protect:

Move the write-protect switch to the right side (to align with the

mark-7’).

This

djzjables writing into the memory card.

To cancel the write-protect:

Move the write-protect switch to the left

side (away from the mark

“V”).

This

enables writing into the memory card.
