1. Please use the standard card access password to access the card.
Non-standard pickup pins may not match, so Cato cannot be removed. Please use a standard card-taking needle, insert it vertically into the top pinhole, and press it inward with a little force. When the card holder pops up, take it out. Please pay attention to distinguish between the top pinhole and the microphone hole.
* Note:
