1. Confirm the recorder and phone Bluetooth are on.
2. On Android 7–11, turn on the phone's system Location switch; Android requires it for BLE scanning.
3. Keep the phone close to the recorder and reopen the device list.
4. To change recorders, select the other recorder directly. You do not need to disconnect first.

Continuous mode records until stopped or a file segment ends. Voice-activated mode waits during silence and writes when speech is detected. A short detection delay after startup is normal. Two presses on the recorder switch the recording mode.

Open Recordings, choose the recorder source, and select the download control for a file. Keep the phone near the recorder for stable speed. Android shows a transfer notification while a user-started download is active; use its stop action to cancel safely.

Connect the recorder and start Live Audio from the Record screen. Accept the one-time system pairing request for that recorder. Keep the App in the foreground. Live Audio stops when the App goes to the background and is not saved or uploaded by the App.

Set the power-on time, power-off time, and repeat option first. Enable Timed recording and wait for confirmation, then move the recorder's power switch to OFF. Manually powering on the recorder cancels the pending schedule.

Power off before inserting or removing a card. Back up accessible files before formatting. Formatting permanently erases recorder storage. Do not disconnect power while formatting or updating firmware.

• Press PB1 once to show battery status.
• Press twice to switch continuous/voice-activated recording.
• Press three times to turn indicator lights on or off.
• Hold for about two seconds to turn BLE on or off.
• Hold for about eight seconds to reset device ownership and BLE bonds; recordings are kept.

Keep the recorder charged and the phone nearby. Do not power off the recorder during installation. The App accepts only signed firmware that matches the supported AOTAOREC product and hardware revision.
