Mute Button The mute button must be reset each time we turn on the computer. Is there a work around? thanks

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.
Highway/City Mode 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.
Highway Mode City 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.

Check two things: first does the set have sound with just a DVD etc connected to one of the rear audio/video inputs? Second is check in menu that speakers are not turned OFF.

Reset the SMC


When the above 5 steps didn't prove to of much help you can try resetting the SMC.
Close the Mac.
Detach any peripherals, cables, power wires, battery etc.
Be patient for several minutes.
Re-attach all the cables, peripherals like before.
Now turn ON the OS X

Try disconnecting the power (completely) for a few minutes. Maybe that will cause a reset of the faulty function.

try repair before you coz more damage

Where is the mute button on an RFX9500?

the only mute function is to mute/unmute a call during the active call.
It is the - key (center button at the top of the keypad)
Have you turned the volume too low?
If you turn the volume to low, it will stay low all the time until you reset it to a higher level.
You just press the volume keys on the side of the flip lid or set in the setup menu.

HERE is your manual in PDF format.

This unit doesnt have a volume mute function.

What are the problems you are experiencing.

If it says Mute or ATT on the display - it is the cellular mute function turning off the volume for an incoming call.

Page 34 details turning on and off the cellular mute function.

You also may try a hard reset by removing the face, and pressing the reset button.
