Setup
Charging the Mirror
Your mirror is equipped with a rechargeable battery. Locate the charging port at the base of the mirror. Connect the provided charging cable. The indicator light at the base will blink red when charging and turn green when fully charged. A full charge can last up to 5 weeks.
Optional Battery Installation
For cordless operation without recharging, the mirror can also be powered by 4 AA batteries (not included). Open the battery compartment on the underside of the base and insert the batteries according to the polarity markings.
Operating Instructions
Power On/Off and Sensor Activation
The mirror features a motion sensor that automatically illuminates the Tru-lux light system as your face approaches. The light will dim and turn off when you move away to conserve power. To manually turn the mirror on or off, press the button located on the base.
Magnification Settings
The Sensor Mirror Trio provides three magnification options:
- 5x Magnification: View your entire face in exceptional detail.
- 1x True View: For a natural, unmagnified reflection.
- 10x Detail Window: Integrated within the 1x side for precise tasks like applying eyeliner.
To switch between the 5x magnification side and the 1x/10x side, simply flip the mirror head.

Adjusting Brightness and Light Settings
The Tru-lux light system simulates natural sunlight (800 lux, CRI 95) for accurate color rendering. It also includes a candlelight setting for checking your look in low-light environments. To adjust the brightness, use the touch-control feature on the mirror's surface or the back of the mirror. Slide your finger along the designated area to increase or decrease the light intensity. To switch between natural sunlight and candlelight settings, press the button on the base or the back of the mirror (if applicable).
Mirror Adjustment
The mirror head can be swiveled and tilted to achieve your desired viewing angle, whether you are seated or standing.

Maintenance
Cleaning
To clean the mirror, use a soft, lint-free cloth. Do not use abrasive cleaners or solvents, as these may damage the mirror's finish or optical coating.
Battery Indicator
The LED indicator light at the base of the mirror will signal battery status:
- Blinking Red: Battery is low and requires charging.
- Solid Green: Battery is fully charged.
Troubleshooting
Light Not Activating
- Ensure the mirror is charged or has fresh batteries installed.
- Verify that the motion sensor is not obstructed.
- If the light is manually turned off, press the power button on the base to reactivate the sensor.
Inconsistent Light Brightness
- Check the touch-control area for any obstructions or residue.
- Ensure the mirror is fully charged, as low battery can affect light performance.
Mirror Not Holding a Charge
- Confirm the charging cable is securely connected to both the mirror and a power source.
- Allow sufficient time for a full charge (one charge lasts up to 5 weeks).
- If issues persist, contact simplehuman customer support.
