Trying to source a replacement Audio/Mute switch for an old Uniden RD9XL around a 1989 vintage. I don't believe there is any direct support for the model any longer, but the rubber/vinyl coated 2 position switch itself may be able to be tracked down from old service diagrams w/parts listing callouts. Reply to email@example.com Thanks in advance!

When changing the Settings on your detector, please keep in mind: Each time the unit is turned On the factory settings of Highway and Auto Mute-On will be set. They can be changed while the unit is in use as described in the following sections.
Assistance Muting An Alert
Your detector allows you to quickly turn Off an audio Alert by momentarily pressing the Mute button. If you press the Mute button a second time during the Alert, the audio Alert will be turned back On.
Auto Mute Mode
Auto Mute will automatically reduce the audio volume of all alerts after four (4) seconds for as long as the signal is detected. The factory setting for Auto Mute is On.
Setting your detector to City mode delays all X band audio alerts at lower signal strength levels. (A single beep will sound when the signal is first Notice detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers. To change settings, follow the procedure listed below, which indicates what you will see and hear as you complete each step. The factory setting is Highway mode.
Mute Button Press and release
To Turn Auto Mute Off
X Ka L S
City Button Press and release
Press and release the Mute button while no alert is occurring.
This model has been out of production for quite some time. You could try contacting Uniden to see if, by chance, they still have some replacement speakers for this older RD model. In any event, you would be well served to purchase a modern radar detector which provides far better performance. Personally, I recommend products produced by the following manufacturers:
Bel Escort Whistler (their higher end products -- XTR-690 model or higher. Their Pro78 or newer Pro78SE is one of my favorites.) Valentine
The instruction manual is not available anywhere online that I can find. Have you tried contacting Uniden for a replacement manual? Your one other source for the manual would be to create an eBay saved search with the following search terms:
LED Display gives you your display visual alerts, signal strength, and operation mode. Here is an attached link for the manual.....http://www.uniden.com/pdf/LRD6399SWSom.pdf But to answer your question here is what the difference between the green light and the red light are: 1. X-Band Signal Indicator—A green LED lights and blinks to indicate the presence of an X-band radar signal. The blink rate increases as the radar source gets closer. A distinct audio alert is also heard. 2. K-Band Indicator— An amber (orange) LED lights and blinks to indicate the presence of a K-band radar. The blink rate increases as the radar source gets closer. A distinct audio alert is also heard. 3. Ka-SuperWideband Signal Indicator— A yellow LED lights and blinks to indicate the presence of a Ka-SuperWideband radar signal. The blink rate increases as the radar source gets closer. A distinct audio alert is also heard. 4. Laser Signal Indicator— A red LED under L lights and blinks to indicate the presence of a laser signal. A distinct audio alert is also heard. 5. SWS Signal Indicator— When an early warning hazard or informational signal is detected, the yellow SWS LED begins to blink and the amber K-band LED lights. A distinct audio alert is also heard. 6. Power-On Indicator— A green LED under P lights to indicate power is being supplied to the unit and the unit is turned on. 7. LED Signal Strength Meter—Four LEDs give an accurate visual indication of the strength of radar or laser signals. 8. City Mode Indicator—A green LED under C lights to indicate that you selected City Mode. 9. Auto Mute Indicator— A red LED under M lights to indicate that you selected the Auto Mute feature. Please make sure you give me a rating and I hope this helps, cbinny1
