4. Setup
4.1. Initial Charging
Before first use, fully charge the pen. Unscrew the pen to reveal the USB port. Connect the pen to a computer's USB port or a USB wall adapter using the provided USB cable. The LED indicator will show charging status (refer to specific LED behavior in Section 5.4). A full charge typically takes approximately 2 hours and provides up to 2 hours of continuous recording.
4.2. Inserting the MicroSD Card
The zPen-HD requires a MicroSD card for storing recordings. Gently insert a MicroSD card (up to 8GB for this model) into the designated slot until it clicks into place. Ensure the card is inserted correctly to avoid damage. If the card is new or causing issues, it is recommended to format it via a computer before use.
4.3. Setting Date and Time Stamp
To enable or disable the date and time stamp on your recordings, connect the pen to a computer. A removable drive will appear. Create a text file (e.g., time.txt) in the root directory of the pen's storage. Edit this file with the current date and time in the specified format (e.g., YYYY-MM-DD HH:MM:SS). Save the file and safely eject the pen. Refer to the specific instructions provided with your device for the exact file name and format, as this can vary.
5. Operating Instructions
5.1. Power On/Off
- Power On: Press and hold the operation button for approximately 2-3 seconds. The LED indicator will illuminate, indicating the device is powered on and in standby mode.
- Power Off: Press and hold the operation button for approximately 5 seconds. The LED indicator will turn off, signifying the device is powered down. The device will also power off automatically after a period of inactivity to conserve battery.
5.2. Video Recording
From standby mode:
- Press the operation button once briefly. The LED indicator will flash discreetly a few times and then turn off, indicating that video recording has started.

The LED indicator will flash differently (refer to your specific model's LED pattern) to indicate audio recording. Repeat the action to stop. The zPen-HD captures synchronized audio with video recordings.
