1.1 Feature
This document describes briefly the board level operations, key features and the
environment of the M4 Platform. The purpose of this platform is the verification of LG
LTE ASIC, namely ‘L1000’, and the evaluation of LG UE system performance. The
further details about the characteristics and functions of L1000 are available on other
documents.

3.4 External Power description
3.4 External Power description
To operate and charge the battery, plug the AC Adapter into a standard wall outlet
and connect it to the LTE trial device via the DC input jack Connector.
External power supply is DC input jack or TA. This power supply specification is
below.

3.5. Battery description
3.5 Battery description
Our LTE Trial device has a battery is used for operating LTE modem part.
Battery Capacity for used in LTE is 2400mAh.
If the battery’s charge is completely run down, it takes 6 to 7 hours to fully recharge.
But this battery capacity is not enough to operate LTE capability; you should external
power supply, which is TA (Travel Adaptor). The mandatory power supply of the LTE
UE is supplied by TA which is distributed by the LGE.
