Battery Information
The Go Direct Light and Color contains a small lithium-ion battery in the case.
The system is designed to consume very little power and not put heavy
demands on the battery. Although the battery is warranted for one year, the
expected battery life should be several years. Replacement batteries are available
from Vernier (order code: GDX-BAT-300).
Storage and Maintenance
To store the Go Direct Light and Color for extended periods of time, put the
device in sleep mode by holding the button down for at least three seconds. The
red LED will stop flashing to show that the unit is in sleep mode. Over several
months, the battery will discharge but will not be damaged. After such storage,
charge the device for a few hours, and the unit will be ready to go.
Exposing the battery to temperatures over 35°C (95°F) will reduce its lifespan. If
possible, store the device in an area that is not exposed to temperature extremes.
