battery power by using the backlight timeout feature. Backlight timeout is a low-power state that will
cause the device’s touch screen to dim slightly. You can program your device to automatically go into this
low-power mode if it has been inactive for a specific amount of time.
Note:
Step-by-step instructions for adjusting screen brightness and using backlight timeout are
available in the
Basic Step-by-Steps
section of this manual.
Another way to conserve battery power is to use the DC adapter/charger that was shipped with your
device. If you are near an electrical outlet, you can use your DV4/MT4 while it is plugged in. To use the
charger while you are programming your device or using it to communicate:
1. Connect the two pieces of the DC adapter/charger.
2. Plug the adapter into an electrical outlet.
3. Shut down your device.
4. Plug the charger jack into the charger port on the right side of your device.
5. Turn the device back on.
Charging the Battery
When the DV4/MT4 battery begins to run out of power, a small, red battery icon will appear in
the title bar at the top of the touch screen. This icon indicates that you should plug in your
device to conserve the remaining power. You should recharge the battery as soon as possible.
The icon will remain until the battery is recharged.
When the battery runs out of power, the device will power down completely. Any unsaved programming
will be automatically saved before the device shuts down. You will need to plug in the charger before you
can turn the device on again.
Whenever the DC power adapter/charger is plugged in and connected to the device, the battery is being
charged. The amber LED on your device’s case will light up to indicate that the battery is being charged.
It will take approximately 9 hours for the DV4 battery to fully charge. The MT4 battery can be fully
charged in about 6 hours. When the battery is completely charged, the LED will go out. You cannot
overcharge the battery, so do not be concerned about leaving the unit plugged in overnight.
You can charge the device’s battery by following these steps:
1. Connect the two pieces of the DC adapter/charger.
2. Plug the adapter into an electrical outlet.
3. Shut down your device.
