I just got my new 106 got it home ready to program and when I plug it in nothing. It work with the half dead rechargable batteries but nothing while plugged in? Any info please
If the radio works on batteries then chances are very good, as mentioned above, that the issue lies with the wall wart and/or adapter plug you got with the wall wart. First, insure that the adapta plug is Type "C". The wrong size plug will fit in the radio but not make contact with the power jack properly. I know because I tried it with 4 different plugs that fit OK and did disconnect the batteries but didn't power up the radio. Second, as was mentioned above, insure that the jack is plugged in to the adapter cord to make sure the tip (center connector) is +. Last, make sure you have the proper adapter that provides 9 volts @ 600 ma (or more ma).
Whatever battery carrier, black or yellow, is in or not in the radio has absolutely no bearing on powering up the radio from the AC adapter. The battery power is totally disconnected when plugged into an AC adapter. There is an additional contact on the yellow rechargeable holder that also allows power from the adapter to provide a charge voltage to the rechargeable batteries but that's all.
One final warning when you do sort out the adapter issue, don't recharge batteries in the scanner. Can damage the batteries as well as the scanner as there is absolutely no battery charge smarts in the 106. Plenty in the forums about this topic and some users have had that damage.
