| 02 ENG   IMPORTANT SAFETY INSTRUCTIONS   N O TICES:   1. Fully charge the Ni-MH battery before using it for the first time or reusing it after   being stored for a long period. It would need 3 to 5 circles of charging and   discharging operations to get the optimum performance of the battery.   2. The surrounding temperature has much to do with the charging efficiency and   O O should be between 0 C and 40 C. The charging performance will be in the most   O O efficient state from 10 C to 30 C.   3. It is suggested to carry out the actions of charging and discharging the battery   at least every one or two months if the battery is stored for a long time. Fully   recharge it again to be stored. This action can avoid the leakage or the bad   performance of the battery for its self-discharging action.   MOBILE ENTERTAINMENT   CONTENTS   ENG 03   DTV MENU   IMPORTANT SAFETY   INSTRUCTIONS   GENERAL STEPS OF SETUP...............17   IMPORTANT SAFETY   INSTRUCTIONS.......................................1   DTV CHANNEL   TV CHANNELS   PACKAGE CONTENTS   AND RADIO CHANNELS ......................   FAVORITE..............................................   18   18   PACKAGE CONTENTS .........................   4 DTV CONFIGURATION   PARTS IDENTIFICATION   SYSTEM SETTING................................   20   AUTO SCAN...........................................   MAIN UNIT...............................................   MAIN UNIT CONTROL SECTION...........   MAIN UNIT LEFT SIDE............................   5 5 6 25   MANUAL SCAN.....................................   25   MAIN UNIT RIGHT PANEL.......................   7 MAIN UNIT REAR SIDE...........................   8 GAME   8 HOW TO STAND......................................   REMOTE CONTROL...............................   KEY DESCRIPTION   BOXMAN................................................   9 26   BURNING TETRIS.................................   HIT RAT..................................................   26   27   OF REMOTE CONTROL........................   10   NOTES ON USING THE   REMOTE CONTROL UNIT......................   11   REPLACING THE BATTERY...................   11   FM INSTRUCTIONS   FM...........................................................   28   DTV PARTS IDENTIFICATION   SPECIAL KEYS......................................   12   OTHERS   DIMENSION AND PARAMETER............   30   USB PLAYBACK   OPERATIONS   TECHNICAL INFORMATION   USING THE USB PORT.........................   15   TROUBLE SHOOTING..........................   31   MOBILE ENTERTAINMENT   04 ENG   PACKAGE CONTENTS   P A CKAG E C O N TEN TS   After unpacking, first check that all the accessories listed below are included:   Access ory bag   AC / DC adapter   Audio a nd vi deo ca bles   MTVOD8E5L0NO.   OPERATING INSTRUCTIONS   Di   g o i t al   V i d eo   B r a d c a s t i ng   Carryin g bag   Operating manual   Remot e control   Car power cable   Car b ag   Mini-magnetic Antenna   NOTES:Actual products' appearance might vary slightly from the pictures shown.   MOBILE ENTERTAINMENT   PARTS IDENTIFICATION   ENG 05   M AI N U N IT   1 2 My   FM   3 4 1.Liquid crystal display   2.Speakers   3.Control section   Control buttons.   4.Remote control sensor   The remote control signals are received from here.   M AI N U N IT CO N TRO L SEC TIO N   MyFM   1.ADJUST button   Press it to enter the adjustment menu.
