At the Sensor Settings screen the internal radio can be configured with default channel, proto-
col 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.
The latest version of the instrument firmware is available from the GeoMax website.
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 confirma-
tion message is shown once the option has been activated.
4.3 Batteries
4.3.1 Operating Principles
•
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 tem-
perature 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 recom-
mended 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 Geo-
Max product deviates significantly form the actual battery capacity available.
•
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 temper-
atures reduce the service life of the battery.
