If the keypad on your Radio Shack Scanner isn't working, it might be locked. Try pressing the FUNC KEY/ LIGHT key to unlock it. If that doesn't work, the scanner may need to be initialized. Follow the steps in 'Initializing the Scanner to Factory Defaults'.
Why does my Radio Shack 20-106 have poor reception?
If your Radio Shack Scanner has poor or no reception, several factors could be responsible. Weak or completely discharged batteries can cause this, so check the batteries or ensure the AC or DC adapter is properly connected. Weak signals might be the issue, so try repositioning the radio. The attenuator might be affecting reception; test performance with and without it activated to find the best setting. Strong signal overload could also be the problem; again, test the attenuator settings. Inspect the antenna and connectors for any issues. Finally, ensure the correct modulation mode is selected for the system you're monitoring.
What to do if my Radio Shack 20-106 won’t turn on?
If your Radio Shack Scanner won’t power on, it might not be receiving power. Try recharging the rechargeable batteries or replacing the non-rechargeable batteries. Also, ensure that the adapter’s barrel plug is fully plugged into the DC 9V jack.
Why is my Radio Shack 20-106 Scanner flashing?
If your Radio Shack Scanner is flashing, it typically indicates that the batteries are low. Recharge the rechargeable batteries or replace the alkaline batteries to resolve this issue.
Why does my Radio Shack Scanner scan slowly?
If your Radio Shack Scanner scans slowly or stops on noise or silence, the SQUELCH control may not be set properly. Set SQUELCH per 'Turning on the Scanner and Setting Squelch' on page 23. Also, the subaudible squelch mode might not be set correctly for conventional objects. Set the correct subaudible squelch mode, refer to 'Appendix B: Detailed Menu Reference: Conv Menu' on page 108.
Why won't my Radio Shack 20-106 Scanner receive digital transmissions?
If your Radio Shack Scanner doesn't receive digital transmissions, the digital channel or talkgroup may not be using APCO-25 digital modulation; the scanner can only receive APCO-25 C4FM/CQPSK IMBE digital signals. Also, the digital channel or talkgroup might be encrypted, and the scanner will not receive encrypted traffic. Finally, the transmission could be from a distant location, so reposition the scanner or use an outdoor antenna to improve reception.
What to do if Radio Shack 20-106 Scanner shows error when uploading from computer?
If you see an error message when trying to upload or download from a computer to your Radio Shack Scanner, and your computer uses Windows XP, it may be missing the necessary USB cable driver. Download and install the file: 'Windows XP Driver to resolve PC connection error' from your scanner’s Product Support page or the Software Download page on www.RadioShack.com. Then make your connection and try again. Be sure the correct COM port is selected in device manager.
