ATTENTION!
• The internal lithium battery is rechargeable and should never be disconnected from the transmitter card
when it is powered by the mains voltage. If this operation should be carried out it could irreparably damage
the transmitter board.
• The internal lithium battery is recharged only when the transmitter is connected to the mains supply (LV, LLV,
HV), battery charging condition, and not with the USB connection.
• During charging, the battery symbol appears on the MCP display and flashes blue; see “MEANING OF
FLAGS” page 27 (the colors of the symbols can only be viewed in the virtual display of the MCP interface)
• When the battery charge falls below the minimum potential, battery low, the fixed red battery symbol
appears; see “MEANING OF FLAGS” page 27 (the symbol colors can only be displayed in the virtual
display of the MCP interface). Furthermore, in this charging condition below the minimum potential, the
measurement does not start when the USB cable is connected.
• The thresholds that identify the condition of low battery and battery charging are established by the system
according to the use and settings assigned and therefore there is no fixed values..
• The two battery low and battery charging icons can both be present as each one indicates a different
condition.
GENERAL OPERATING NOTES
• If the mains voltage is disconnected from the transmitter with HV power supply, the flashing blue icon
indicating the charging status can remain active for tens of seconds. This is due to the energy stored in the
HV power supply and in the capacities of the circuit that discharge slowly.
• The battery voltage during charging does not rise immediately but gradually. This is related to the
parameters set in the transmitter and detected by the controller chip.
• When the battery is physically disconnected the potential measured by the system is not true because the
charging circuit checks the battery status by emitting impulses. These load the capacities in the circuit and
the average value detected is not to be considered a reliable real value.
• The MCP command [SBCHS] indicates the percentage of charge and is not linear with respect to the
battery voltage, however approximately it reads 0% with a voltage equal to about 3.2 V, while 100% occurs
with about 4.1 V. These values are influenced by the temperature and the total operating time that worked
the battery.
