Charging the Accent 700
Check your battery status in the Status Display Area
The Battery Status bar graph in the Status Display Area on your screen gives you the following information:
Full Battery: mostly green lines, a few yellow, and a few red
Plug in Charger: when you see only yellow and red lines it is time to charge.
Nearly Dead: red lines only (plug in charger now) to prevent losing new programming.
Charger Plugged in: you will have blue lines on the bar graph.
The Battery Menu
Go to the Toolbox and select the MAINTENANCE MENU 
Select the Battery Menu option. 
You can activate the Next Battery or Previous Battery option to make sure you are seeing the latest battery information.
Low Battery Warning
When the batteries in your device get low, you will hear a Low Battery Warning. This is a two-toned running beep. When the Low Battery warning sounds, you can no longer do any storing. The warning will continue to sound at intervals until the batteries are dead. When the batteries are dead, the device powers down completely and you cannot use it.
Battery LED
There is one LED on the top right / front of the screen.
The LED will blink a red battery icon when the device has a VERY LOW battery charge and battery charger is plugged in.
Once there is some charge in the battery pack, the LED will have a solid red battery icon when the batteries are charging.
IMPORTANT! Forcing the charger tip in too far will damage your device!
A complete charge, from dead battery to fully-charged battery, will take 3 - 4 hours. Your charging LED will turn solid blue when the battery is full.
