To Next PageTo Next PageWhy is my Radio Shack 20-135 on but not scanning?
If your Radio Shack Scanner is on but not scanning, it might be due to the squelch not being adjusted correctly. Try adjusting the squelch. Alternatively, only one or no channels may be stored; store frequencies into more than one channel to resolve this.
Why won’t my Radio Shack 20-135 work at all?
If your Radio Shack Scanner is not working at all, ensure it's receiving power by either recharging the rechargeable batteries or replacing the non-rechargeable batteries. Also, verify that the AC adapter or DC adapter is properly connected to the DC 9V 300 mA jack.
What to do if the keypad doesn’t work on my Radio Shack 20-135?
If the keypad on your Radio Shack Scanner isn’t working, it's possible that the keylock function is activated. To deactivate it, press and hold /KEYLOCK until the keylock indicator disappears.
What to do if the signal is flashing on my Radio Shack 20-135 Scanner?
If your Radio Shack Scanner displays a flashing signal, it likely indicates that the batteries are low. To resolve this, recharge the rechargeable batteries or replace the alkaline batteries.
How to fix poor reception on Radio Shack Scanner?
If you're experiencing poor or no reception on your Radio Shack Scanner, first check the batteries. Weak or completely discharged batteries can cause this issue, so ensure they are checked or that the AC adapter or DC adapter is connected properly. Also, make sure an antenna is connected to the scanner, as a loose antenna can also lead to poor reception.
What to do if 'Error' appears on Radio Shack Scanner?
If an error appears on your Radio Shack Scanner, it indicates a programming error. Re-enter the frequency correctly, making sure to include the decimal point.
