Clean your battery contacts on the battery and charger with a pencil eraser to assure good contact. Flashing red or flashing in general usually is the sign of a too low to charge battery, a shorted battery or a bad connection. In some instances, a battery will begin to charge once left on the flashing charger for an hour or so. Try this and see if the light becomes constant. If so, it is charging. If it still flashes, replace the battery.

Best regards.

The battery is charged but the lights just flash and chair doesn't move


Make sure the charger is unplugged from the chair and that the chair is in gear. There's two levers that place the chair in freewheel, or neutral so you can roll it around. Place these in neutral, then back in gear firmly. If still flashing, turn chair off, wait three seconds and turn back on, then push on the horn button three times. This will take it out of sleep mode. Still not going, you will need to check all clip-on connections to make sure they are tight.

I am assuming that all of the lights are flashing constantly. If it flashes a "fault code", you will get a series of flashes from 1 to 10, then a pause, then a set of flashes. Count the number of flashes and it will tell you what the fault is for that number of flashes in the owners manual. If it is just two red lights flashing constantly, you have a set of dead batteries.

Good luck.

Whenever your dsl light on the 2wire modem turns red,it only means that there is a problem with the dsl connection to the modem. Here are some ways on how you can isolate the problem

My intercom button flashed red to green. When I push a line button, I get a two-tone beep but no dial tone. I changed the internal 9 v battery. I unplugged the phone and waited, then plugged it back in....


Each telephone must be connected to line 1 and line 2 for
proper operation. The remaining lines 3 and 4 may — or may not —
be connected to each station as you desire. First plug in the battery, then the phone lines (1 & 2 are mandatory), and third the power cord. If your intercome LED is blinking red and green, then press: STORE IN, followed by "INTERCOM" followed by a free intercom# (i.e., any of the memory buttons 1 through 16 not already assigned to another telephone set). Then wait for the phone to go through its initiation sequence during which it searches each of the four possible lines. After that concludes, you should get dial tone on your active lines. :-) Marco
