because it is not plugged
Hold down the 1 and 2 buttons at the same time. If you don't get flashing lights at the bottom, your remotes are broken or out of batteries. If you do get flashing lights, good. That means your remote is in discovery mode. If that works, try syncing with the console via the red sync button under the wii remote (in the battery area) and the red sync button on the console.
it should work fine unless you have it unplugged for too long. i have replaced batteries in these cars before and did not have to reset the radio
It could be that the batteries are getting old and need to be replaced.
because they run out of energy
I had the same thing happen. I replaced the batteries in the outdoor sensor, but just got the two dashes on the clock that should display the outside temperature. After I replaced the batteries in the clock itself, the outside temperature then showed up properly on the clock. I also took all batteries out of both devices and replaced them in the order recommended in the directions on the back of the clock. I hope that helps.
odds are the sensor needs to be replaced
batteries need to be replaced
The batteries may not be in correctly.
Most of the material is recycled.
Correct new and used batteries should not be mixed together due to reduced life span and other potential hazards from mixing. Batteries when being replaced should always be replaced with new batteries of the same size and brand if possible.
Sump pump batteries typically last around 3-5 years before needing to be replaced.
Canon batteries typically last for about 2-3 years before needing to be replaced, depending on usage and charging habits.
