Other Troubleshooting For Uniden BC75xLT All Lockout

Sometimes, even after programming the scanner, you still can face this problem. Like troubleshooting the Delphi radio, all the radios and scanner problems can somehow be fixed by troubleshooting. 

Here is a troubleshooting guide that you have to perform step by step. 

Replace the Batteries:

If the battery is drained or has a low charge, it can cause this all-lockout problem. So replace the batteries and try again. This scanner runs on two AA batteries. You can use either rechargeable AA batteries or AA alkaline batteries whatever you prefer. 

You also have to set the battery setting to the battery type you are using. For example, if you are using rechargeable batteries, set the battery settings to rechargeable. While using alkaline batteries, set it to alkaline.

Recharge the Batteries:

If you are using rechargeable batteries make sure to charge them properly. And try to charge them with a different USB to make sure the current USB isn’t faulty. Also, while charging the battery, the scanner must be turned Off. 

Using pre-charged batteries is the best idea as charging through the device requires a long time. 

Faulty Device:

If nothing of the above works, there must be a fault in the device. Especially if you have purchased a refurbished product. For example, faulty wiring, a faulty switch, or faulty units. 

The wiring of these scanners easily gets ruined and replacing them is complicated as all the wiring of Uniden scanners is not the same as pioneer wiring. Pioneer uses the same wiring harness in all models for fewer complications. 

In this case, the repair cost is almost half the price of a new scanner, and repairing is not worth it. So, better if you can send back the product and buy another from a trusted dealer.
