The Battery
The phone comes with a rechargeable battery. Keep the battery
charged while not in use in order to maximize talk and standby
time. The battery charge level is shown at the top of the LCD
screen.
Installing the Battery
To install the battery, insert the bottom of the battery into the
opening on the back of the phone. Push the battery down until
the latch clicks.
Removing the Battery
Turn the power off. Lift the release latch to detach the battery.
Charging the Battery
To use the charger provided with your phone:
Warning! Use only the charger provided with the phone. Using
any charger other than the one included with the LG5400 may
damage your phone or battery.
1. Plug the round end of the adapter into the phone’s charger
jack and the other end into an electrical outlet.
2. The charge time varies depending upon the battery level.
The maximum charge time for a fully discharged battery is
3.5 hours.
NOTE: It is important to fully charge the battery before
initial use of the phone.
Battery Charge Level
The battery charge level is shown at the top right of the LCD screen.
When the battery charge level becomes low, the low battery sensor
alerts you in three ways: sounding an audible tone, blinking the
battery icon, and displaying LOW BATTERY WARNING! If the battery
charge level becomes exceedingly low, the phone automatically
switches off and any function in progress is not saved.
Turning the Phone On and Off
Turning the Phone On
1. Install a charged battery or connect the phone to an external
power source such as a cigarette lighter charger or hands-
free car kit.
2. Press for a few seconds until the LCD screen lights up.
Turning the Phone Off
1. Press and hold until the display turns off.
Signal Strength
Call quality depends on the signal strength in your area. The signal
strength is indicated on the screen as the number of bars next to the
signal strength icon: The more bars, the better the signal strength. If
the signal quality is poor, move to an open area. If you are in a
building, the reception may be better near a window.
NOTE: Like any other radio device, avoid any unnecessary
contact with the antenna while your phone is on.
