No. 1 Item No Power even the Possibility Main Battery low power exhausted. reflected on the panel and in a dim location, it looks like the unit is turned OFF. According to the Power Management settings, the units will be switched OFF automatically. 2 Battery discharges quickly The battery life depends on the devices being used in SD Card Slot, and frequency of use of the Back light. These functions consume a lot of energy. Operating with front light ON, or using high energy consumption devices such as SD Memory Card will drain out the battery pack faster. 3 Battery cannot be charged Using AC adapter that is NOT supplied with the unit. Charging the battery while operating the unit with heavy loadings could cause the temperature inside the unit to build up which could cause the unit stop charging. At this moment, the LED indicator will flash Yellow to notify user that the charging has been stopped. Or the temperature is extremely low will also stop charging. Since the extreme high or low temperature will cause the battery to discharge quickly, it has been designed to cut battery charge below 0 and above 35~40 to protect the battery pack. 4 Cannot make communications via mobile phones through exclusive cable. If the unit could pass the test with Loop back Interface card, the possibility of unit malfunction becomes low. Then the following items could be the reason of problem such as location, timing, signal strength, service provider's mixed up, or problem with the mobile itself. Or could be incompatibility issue.
