Refer to the instructions that came with charger. If you threw them away you have a problem You can go on line and download instructions.
Low Charge Alert (LCA)
On the front of the unit there is a Low Charge Alert port. There is a red plug in this port. With the plug
removed, when the battery level drops to LO, an alarm will sound to remind the user to recharge the
Jump-Starter.
The alarm can be turned off one of three ways:
•
Placing the pin back into the Low Charge Alert port
•
Recharging the battery immediately to bring it to the capacity of 10% or more
•
Pressing the battery indicator display button. If the alarm is turned off by pressing the battery
display button, the alarm will sound automatically again in approximately 1 hour.
The alarm will only be turned off permanently if the battery is in a fully charged state, or the pin is
inserted in the Low Charge Alert port. There is a storage port on the back of the Jump-Starter for the
LCA plug. When the plug is removed from the LCA port, it should be installed in the storage port on the
back of the Jump-Starter.
Charging Jump-Starter Battery
All rechargeable batteries gradually discharge when left idle, and you need to recharge them
periodically to maintain maximum battery capacity. The AC charger plug within the Jump-Starter is
designed to charge using a 110/120-volt outlet.
•
Fully charge unit to the recommended maximum and initial charge time of 24 hours. Thereafter, an
AC typical charge time is 8 to 12 hours.
•
Recharge the unit fully after each use. This will prolong the life of the battery because frequent
discharges between recharges will reduce battery life.
•
Make sure all functions of the Jump-Starter are turned off during recharging

It means you need to recharge the battery of the camera.

You can't recharge the camera's battery the same way you recharge a smartphone or a tablet, it probably won't recharge if you plug it to an USB port/recharger.

Take a look at the camera's manual, probably your camera came with a battery charger, and you need to open the camera, extract the battery and use the charger.

Take a look at the camera's manual.

recharging what --if you have the manual read it about charging

This is not a Camera

Just to be clear: you can either buy the rechargeable battery or regular batteries of the same type. I'd rather get the rechargeable battery, saves a TON of money.
To recharge a battery, you need a charger for the battery - they come in plugs for the wall or for the car. Just place the battery in the charger, plug it in. It depends on the brand, but usually there is a little button that will glow red but when it is fully charged it will change to green.
I'll put a picture on here for you. The battery itself is "KLIC-8000".

to recharge your rechargeable batterie you plug the holder that hold the batteries into the wall, then a green light should turn on. That should help you out! :)

It takes bout in hour.


But thats how mine work

Make sure the hold/lock is not engaged- it will prevent the player from charging.

The blinking went away as I had charged it for a very long time. However, it was noted that it would not work on the DVD. The battery needs to be replaced. That solved my problem. I still have to look for a new battery for this device: US Logic 680p DVD player with recharging capabilities due to the portability option. It works fine if plugged in, but the battery just needs to be replaced if I want to use it independent of the plug. Thanks for asking how I resolved the issue.

All batteries die sooner or later. I believe you have a dead cell.

1) Find another machine that uses the same battery and try it or
2) try another battery or
3) Give up and buy a new battery.

Good luck.

When you purchased the camera, there should have been a charge in the box (you got a lithium-ion rechargable battery with the camera, no?). You put the battery in the charger and plug the charger in the wall.
