Step Description
1. Start the web browser on your PC/CS field controller.

Ensure that your GS GNSS instrument is still running and the Blue-
tooth connection between PC /CS field controller and GS is estab-
lished.
2. Type in 192.168.253.2. The Web server is started. You will see the home
functions following:

Batteries

Operating Principles

• The battery must be charged prior to using it for the first time.
• The permissible temperature range for charging is between 0°C to +40°C/ +32°F to
+104°F. For optimal charging, we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers
recommended by Leica Geosystems, it is not possible to charge the battery if the
temperature is too high.
• For Li-Ion batteries, a single refreshing cycle is sufficient. We recommend carrying
out a refreshing cycle when the battery capacity indicated on the charger or on a
Leica Geosystems product deviates significantly from the actual battery capacity
available.
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating
temperatures reduce the service life of the battery.
When the GS25 GNSS instrument is connected to an external power while the internal
battery is inserted, the internal battery is automatically charged.

When the GS25 is turned on, the battery charging status is indicated in the
GS25 Web server application.
When the GS25 is powered down, battery charging is indicated via the LEDs.
Refer to "4.5 LED Indicators on GS25".
