Why Radio Shack Pro-60 Scanner does not blink nor make peep tone when battery voltage has gone down?
If your Radio Shack Scanner does not blink nor make a peep tone when the battery voltage is low, it could be due to a defective ICS and/or associated circuit. Replacing the defective components may resolve the issue.
What to do if my Radio Shack Scanner does not scan but squelch operates?
If your Radio Shack Scanner is not scanning, but the squelch function is operating, the issue may be a defective CPU (IC1). Replacing IC1 might resolve the problem.
What to do if my Radio Shack Pro-60 display lights up but there is no sound?
If the display of your Radio Shack Scanner lights up, but you're not getting any sound, the issue might stem from several components. It could be a defective speaker or headphone jack, which would need replacement. Alternatively, the problem could lie within the audio amplifier circuit (IC306), IF amplifier (IC301), squelch control (VR301), AF pre-amp circuit (0307), audio mute switching circuit (0308), or the switching circuit (IC303), along with their associated circuits. In such cases, replacing the defective components is recommended.
How to fix a Radio Shack Pro-60 when the display doesn't light up and there is no sound?
If your Radio Shack Scanner's display doesn't light up and no sound is coming out, the issue might be due to several reasons: * **Defective batteries:** Replace them. * **Incorrect battery polarity:** Correct the battery polarity. * **Defective power or charge jack:** Replace the defective jack. * **Defective ON/OFF switch:** Replace the defective switch.
Why sound does not come out in WFM mode but AM and NFM operate on Radio Shack Pro-60?
If the sound doesn't come out in WFM mode on your Radio Shack Scanner, but AM and NFM modes are working, it could be due to a defective IC1 or a defective control circuit (IC303, IC305) and/or its associated circuit. Try replacing the defective components.
What to do if my Radio Shack Pro-60 Scanner searches but does not halt on the correct frequency?
If your Radio Shack Scanner searches but doesn't halt on the correct frequency, it could be due to defective IC303, IC304, IC30S, 0309, 0310, which would need replacement. Alternatively, the discriminator coils T301, T302 might be out of adjustment, in which case, readjusting T301 and/or T302 may solve the problem.
What to do if my Radio Shack Scanner does not operate between 760 and 999.9875 MHz?
If your Radio Shack Scanner does not operate between 760 and 999.9875 MHz, it could be due to a defective 0113 and/or VC02 circuit. Replacing the detective components might resolve this.
Why all bands do not operate but display is OK on my Radio Shack Pro-60?
If all bands do not operate on your Radio Shack Scanner, but the display is OK, it could be due to a defective PLL (IC1 01, IC102, IC1) and/or associated circuit. Replacing the defective components may resolve the issue.
Why is there low sensitivity between 30.000 and 87.495 MHz on my Radio Shack Pro-60 Scanner?
If your Radio Shack Scanner exhibits low sensitivity between 30.000 and 87.495 MHz, the problem may be a defective decoder switching circuit (0101) or a defective bandpass filter (BPF). Replacing 0101 or the defective BPF components might resolve this issue.
What to do if the sound comes out but display does not light on my Radio Shack Pro-60?
If you're getting sound from your Radio Shack Scanner, but the display isn't lighting up, it could be due to a defective LCD or rubber connector, or a defective CPU (IC1). Replacing the defective components, such as the LCD, rubber connector, or IC1, may resolve the issue.
