2.
If maximum operating voltage is exceeded the power protection is activated. The device continues to work, but is
powered by the battery.
3.
If GPRS operates in poor communications, peak consumption (10 ms), consumption of the device can accede 500 mA.
4.
Attention!
Lithium polymer battery (Li-Po) is used in the device. The following rules must be observed during its
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.
The mode in which information received through RS-232 and RS-485 interfaces is not processed by the device, and is
buffered and transmitted to the server as it is.
7.
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.
