2 - If maximum operating voltage is exceeded the power protection is activated. The device continues to work, but
is powered by the battery (if available).
- If GPRS operates in poor communications, peak consumption (10 ms), consumption of the device can accede 500
3
mA.
- Attention! Lithium polymer battery (Li-Po) is used in the device. The following rules must be observed during its
4
operation: not to heat, keep away from sources of heat, not to throw the battery into the fire, not to expose to direct
sunlight. The device, for power of which Li-Po battery is used, cannot be used in high humidity, high and low ambient
temperatures. Operation is permitted under the conditions specified by the manufacturer. Not to hit, not to deform,
not to disassemble, not to close contacts.
5 - Protection against battery charge while it is overcooled or overheated.
6 - Only when using the RS-232/RS-485 interface converter.
7 - To connect the SIGNAL devices to the ATOL Drive 5 tachographs, an UART / RS-232 converter is additionally
required.
8 - A mode in which information received via the RS-232 and RS-485 interfaces is not processed by the device, but
is buffered and transmitted to the server as is.
9 - When the device is stored and used outside the specified temperatures, it is recommended to turn it off and
remove the battery from the device to avoid damage to the battery and to the device.
- If the device is operating outside the specified temperatures, irreversible change in the properties of the Li-Po
10
battery, a decrease in capacity, current output can occur.
