Key Features:
- Magnesium Chassis: Lightweight and durable construction. Note that the chassis thickness may vary slightly, leading to minor weight variations (approximately ±2 grams).
- Ultem Base: The bottom of the mouse is made of Ultem to facilitate wireless signal transmission. This material is not as strong as magnesium and should not be subjected to excessive squeezing.
- Finalsensor: An industry-leading optical sensor with up to 20,000 CPI resolution and 450+ IPS, featuring integrated illumination.
- Godspeed Wireless Technology: Built on the Nordic RF platform (nrf52840) with proprietary firmware, offering reliable and high-performance wireless connectivity with a 1000Hz polling rate.
- Rechargeable Battery: High-end Jauch Lithium Ion battery providing extended usage times.

3. Operating Instructions
3.1 Button Functions
The Starlight-12 Phantom mouse features 6 programmable buttons. Default functions are as follows:
- Left Click
- Right Click

3.3 Power Management and Rest Modes
The Finalsensor is designed to enter various stages of rest mode after periods of inactivity to conserve battery. When the mouse is in a rest mode, there may be a slight delay before it responds to movement. This is normal behavior and does not indicate a performance issue. Moving the mouse will quickly reactivate it to full performance.

The Starlight-12 Phantom uses a rechargeable Jauch Lithium Ion battery. To maximize battery lifespan:
- Avoid fully discharging the battery frequently.
- Store the mouse at room temperature.
- Charge the mouse when the battery indicator suggests low power.
Expected battery life: Continuous use ~160 hours, average use ~3 weeks, below average use ~7 weeks, idle use ~16+ weeks.
