Charging the Batteries
Before using the GR-3, fully charge the batteries for maximum
operating time (Figure 2-8 on page 2-10).
If the batteries are attached to the charging cradle or to the GR-3, an
approximately 6-hour charge cycle will fully charge the batteries; the
batteries charge simultaneously.
The batteries cannot be overcharged.
The batteries are shipped from the factory without
power. Fully charge the batteries before surveying.
