My base doesn't light up the power display and sound display at the bottom. The power button works; however, the volume buttons do not. I also have hooked the dock up to a 2 port USB KVM switch and it does not work while plugged into the dock. However, it does work when the USB is plugged directly into the laptop. I have a Presario V6000 and The dock is plugged into the side with the blue light illuminated. It just appears that anything on the dock doesn't actually work except the power button.

Uniden has the manual for the EXAI2980 here: https://www.uniden.com/File%20Library/FooterNav/Product%20Information/Owners%20Manuals/exai2980om.pdf .

Do you need to adjust the ringer volume of the base, the handsets or both? To set the ringer volume of the base, start with the phone in standby mode (no calls being made or received) then press Menu 4 times (the right-hand button in the row above the volume up/down buttons). You should hear the current ring volume and see it displayed on the LCD screen. Press Set (the left-hand button in the row above the volume buttons). Press Skip/FF or Repeat/RR (the buttons on either side of the Play button below the LCD screen) until the desired ring volume level is displayed. Press Set to save the setting. Press Play/Stop to exit the menu system. See page 38 of the manual (page 40 of the PDF above) for the directions.

To adjust the handset ringer volume, press the handset volume up or down buttons with the phone in standby. The last chosen ringer tone and volume will be saved. See page 16 (page 18 of the PDF). Sometimes, the handset will not ring after losing the security code that pairs it to the base. Remove the handset from the base. Press and hold Page on the base (between Set and Menu). While the handset is sounding the paging tone, replace the handset in the base. Leave the handset in the base until the flashing stops (more than 5 seconds). See page 47 of the manual.

I hope this helps.

If you can get at the controls again----undo or unsolder the micro switch for volume down! Remove it and see if set works.

A no brainer in that if that switch is bad and vol down still displays nothing else would work

NO OS STATED BY YOU
and why you think your PC runs on this X


the last post at HP said
HP 15-r264dx does not have docking port, you have to use USB "dock" such as HP USB 2.0 or USB 3.0 docking stations.

and last here is your correct docking station (you never asked first)

http://h10032.www1.hp.com/ctg/Manual/c01103327.pdf




page 6 shows it dont work on your PC.
so that 2 books that said that.
if does not mention OS, but 2006 we know is XP , never run XP ever.
there are rumors of hacks that can make it work but only no details.
for sure it must be a hardware match.
then you need drivers to run it, but if your OS is not XP
finding them now is very very hard.
only google can find them and I see ZERO

why not ask at HP. the real makers forum.

what did you end up doing? i have the same problem.

Check for buttons on the side of the phone. There should be an up and down button to change the volume either way. If that doesn't work look for setting and then sounds. From there, it should be possible to find a way to change the volume of the ringtone.

This page is for ACER products. Select the DISPLAY, the choose the correct model for your monitor. There select Guides and Manuals. When you get the PDF file open, look for ADJUSTING DISPLAY SETTINGS. (page 6)

This is what was one one product's manual. This is similar to what my HP monitor uses. Hope this helps.

Good luck

If you have a Windows-based computer,
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

Also, check the RCA website for firmware upgrades.

only 1 reason for that faults :

there is a flat connects the top panel which has all the controls with the other circutes in the stereo...
so you have to open it and care for the cd unit it damage easily then check the flat for loseness or cuts
it happened to me also and that works perfectly
good luck

I would assume this could have been a product that was returned to the company that you purchased it from. Follow these instructions. 1. 1. Disconnect power from the base by pulling the plug out of the back of the unit. 2. Press and hold the Page button and while holding the Page button reconnect the power. 3. Continue to hold the Page button until the charge/in use light flashes rapidly. 4. Release the Page button. 5. Press and release the page button on the base once. All handsets are de-registered and HANDSET NEEDS REGISTRATION shows in the display. Then From the Handset Setup Menu: 1. Press the caller ID-volume ( 6 or 5) button to scroll to the REGISTRATION sub-menu. 2. Press the mute/program button to enter the menu. REGISTRATION 1YES 42NO - - -shows in the display. The default setting is 2NO. 3. Use the touch-tone pad to select 1 for YES or 2 for NO. Or use the caller ID-volume ( 6 or 5) button to scroll to 1YES or 2NO. 4. If you select YES, press the mute/program button. HOLD BASE PAGE FOR 5 SECONDS, THEN PRESS HANDSET PROGRAM shows in the display. (Your handset should be held near the base during registration process.) 5. Press and hold the page button on the base unit until the charge/in use indicator flashes. Press the handset mute/program button. REGISTERING shows in the display. HANDSET X REGISTERED shows in the handset display, where X is the handset number. You may now rename your handset. (Refer to Step 3 & 4 of Handset Name Section) NOTE: IF you are re-registering the handset through the handset menu; to rename your handset you must go to the Handset Name Section and start from the beginning step. I understand that you have tried the registation process. Sometimes with electronics, you have to start from ground 0, before it will work correct again. If there are further questions or comments, please post here. Please rate this solutn through fix-it. Thank you
