[faq] Q: How do I turn on the 70Mai 1S? A: Press the Power button. When the dash cam is connected to a cigarette-lighter socket that becomes powered with the vehicle, it can also turn on automatically when the vehicle starts. Q: How do I turn off the 70Mai 1S? A: Press and hold the Power button for normal shutdown. If the dash cam becomes unresponsive, holding the Power button for about 15 seconds can force it to shut down. When connected to a vehicle socket that switches off with the vehicle, the dash cam can also power off automatically after the vehicle is stopped. Q: Why can the dash cam shut down automatically? A: Automatic shutdown can occur when external power is unavailable and the internal battery is low, when battery discharge is limited by ambient temperature, or when the dash cam is operating outside its supported temperature range. Q: Do I need to turn the dash cam on and off manually every trip? A: Usually not when the cigarette-lighter socket switches on and off with the vehicle. The dash cam can start and stop with that power source. Some vehicles keep the socket powered after the vehicle is stopped; in that case, manual shutdown or disconnecting the charger may be appropriate. Q: Can the 70Mai 1S be used without external power? A: Continuous use without external power is not recommended. The built-in battery is mainly intended to support final video storage when external power is removed. If a low-battery message appears, reconnect the charging cable. [/faq] [note] Vehicle power sockets behave differently. Some remain powered even after the vehicle is turned off, so automatic dash cam shutdown may not occur in every car. [/note]Recording
[faq] Q: Do I need to start recording manually? A: No. When the dash cam powers on with a usable microSD card installed, recording starts automatically. On first use or after factory settings are restored, the dash cam may need to be activated through the 70mai app before normal use. Q: Can recording be paused manually? A: No. The dash cam is designed to keep recording driving video and does not provide a normal manual pause function. Q: When can recording stop temporarily? A: Recording can stop while viewing the album in the 70mai app, changing recording-related settings such as system time, formatting the microSD card, restoring factory settings, transferring an update package through the app, or while the dash cam is updating. Recording may also pause if the microSD card cannot maintain sufficient writing speed. Q: How do I know recording is active? A: Check the dash cam indicator. A solid green indicator means normal recording is in progress. [/faq]microSD Card Conditions
- A card below Class 10 may become too slow for reliable recording.
- A card that has accumulated file-system fragmentation after extended use may also show reduced writing performance.
- If recording pauses because of card performance, use a suitable higher-speed card or format the existing card in the dash cam when appropriate.
Video Types and Storage
[compare] Normal video | Default 1-minute clips stored in the Normal video folder using loop recording Emergency video | The current normal recording plus approximately another 30 seconds, stored in the Emergency video folder using loop recording [/compare] [faq] Q: Can the dash cam record sound? A: Yes. Audio recording is disabled by default in the existing 70Mai 1S setup described here. To enable it, open the dash cam page in the 70mai app, enter Device settings, and enable audio recording. Q: Can I change the normal video length? A: Yes. Open the dash cam page in the 70mai app, enter Device settings, select the video-length option, and choose an available length. Emergency-video and parking-surveillance recording lengths are not manually adjustable through this setting. [/faq]Photos and Voice Control
[reference] Title: Take picture Text: Captures a photo. Title: Record video Text: Starts an approximately 30-second emergency recording. Title: Photo Storage Text: Photos are stored in the Photo folder on the microSD card, with space managed using a fixed 300-photo loop mechanism. [/reference] [faq] Q: How can I take a photo? A: Say “Take picture” to the dash cam when voice control is available. After connecting through the 70mai app, you can also use the Take picture control from the preview screen. Q: Which voice commands are listed for the 70Mai 1S? A: “Take picture” captures a photo, while “Record video” starts an approximately 30-second emergency recording. Q: When is voice control unavailable? A: Voice control is unavailable while the dash cam is connected to a phone, during the setup wizard, while formatting the microSD card, while restoring factory settings, during an update, or while album operations are being performed on the dash cam or through the app. [/faq]Battery and Power Care
The 70Mai 1S is intended to operate from vehicle power. Stable external power also reduces unnecessary use of the small internal battery.
[dosdonts] Do: Use the supplied vehicle charger and power cable when available Do: Disconnect the charger or turn off the dash cam if the vehicle keeps the power socket active after parking Do: Disconnect external power when leaving the vehicle parked for a long period if the socket remains powered Do: Keep the dash cam away from extreme heat where practical Dont: Rely on the built-in battery for normal continuous recording Dont: Leave the dash cam powered for long periods in a parked vehicle when the power socket stays active unnecessarily Dont: Disassemble the built-in battery [/dosdonts] [warning] If the battery or dash cam shows unusual heat, deformation, swelling, or liquid leakage, stop using the device and have it checked by qualified service personnel. [/warning] [faq] Q: Why should I disconnect the dash cam in some parked vehicles? A: Some vehicles continue supplying power to the cigarette-lighter socket after the vehicle is stopped. Leaving the dash cam running for a long period can continue drawing power from the vehicle battery. Q: What should I do in very hot parked conditions? A: Avoid leaving the dash cam powered in extreme heat. If the vehicle socket remains powered while the car is parked in direct summer sun, disconnecting the dash cam power cable can prevent it from continuing to operate in those conditions. Q: What happens if I manually turn off the dash cam while the vehicle socket remains powered? A: The dash cam may need to be turned on manually the next time the vehicle is started because the socket itself never cycled from off to on. [/faq]
