Download data At the Data Download Tab select the file that you want to download. Both .DAT and Rinex files can be
directly downloaded. The raw data is transferred from the instrument to PC where it is processed using
the GeoMax Geo Office software.
Radio settings

To meet country radio licence requirements, the internal UHF radio must be set before use to
legally allowed local frequencies as defined by local or governmental authorities. Use of forbidden
frequencies may lead to prosecution and penalties.
At the Sensor Settings screen the internal radio can be configured with default channel, protocol type,
channel spacing, transmission power and unit ID. Various required frequencies can be entered into the
channel table and assigned to a specific channel number.
Sensor firmware The latest version of the instrument firmware is available from the GeoMax website.
License key Optional GNSS receiver licences are activated with a key file.
At the Licence Key file screen browse for the key file on your PC and click Upload. A confirmation
message is shown once the option has been activated.
4.3 Batteries
4.3.1 Operating Principles
Charging / first-time
use
• The battery must be charged prior to using it for the first time because it is delivered with an energy
content as low as possible.
• The permissible temperature range for charging is between -10°C to +55°C / +14°F to + 131°F. For
optimal charging we recommend charging the batteries at a low ambient temperature of +10°C to
+45°C/ +50°F to 113°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers recommended by
GeoMax, it is not possible to charge the battery if the temperature is too high.
• For new batteries or batteries that have been stored for a long time (> three months), it is effectual
to make only one charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We recommend carrying out
the process when the battery capacity indicated on the charger or on a GeoMax product deviates signif-
icantly form the actual battery capacity available.
Operation / Discharging • The batteries can be operated from -20°C to +60°C/-4°F to +140°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating temperatures
reduce the service life of the battery.
