4.11 Memory
The Commander has a 2 GB internal memory. This is sufficient to manage the data of
up to 1,000 logger groups, each with 1,000 loggers.
You can query the available memory space at any time in the system settings (see page
25).
4.12 Power supply
The Commander is fitted with an internal Li-ion rechargeable battery. This can power
the device for approximately 20 hours. The battery’s present charge level is shown
continuously by the battery symbol in the infobar on the screen.
If the battery is low, a warning on a coloured background appears on the screen:
• Yellow background … device can still operate for a few hours
• Red background + warning sound ... device will shortly switch off
The Commander can be operated using an external electricity source. Connect it to the
mains voltage or to your vehicle’s 12 volt socket. A guide on the round plug of the
charging cable and a groove on the charging socket of the Commander specify the
correct alignment of the plug.
As soon as the Commander is connected to the external power supply, its battery is
charged up automatically. This is shown by the red charging indicator light and by the
arrow in the battery symbol at the bottom right of the screen. Charging takes
approximately 12 hours. The battery is fully charged once four bars are shown in the
battery symbol. After the battery is fully charged, the Commander switches to trickle
charging.
CAUTION
During charging, the ambient temperature should be between
10°C and 40°C (50°F and 104°F). Otherwise the device could be damaged!
Only use the supplied charging cable to connect the Commander to
external power sources.
If you experience problems with the battery, please contact your SebaKMT
sales partner. Do not open the device yourself. The stated water- and dirt-
resistance can only be guaranteed if any work on the device is performed
solely by service departments authorised to do so.
The Commander automatically switches off if no input is made within a specified time
period. This timespan can be configured in the system settings (see page 26).
