Reset base My base seems to work fine until someone calls in and when the ring happens it flashes all the buttons and it powers off and reboots. I was told its in a "protected mode" and might go back to normal if I reset it. I do not know how to try this. sorry I dont have a manual and I could not find a pinhole like routers have and it does nothing to unplug it for a while.

Hi,

Please use gloves on your car infotainment system in order to test the responsiveness of the buttons. If this fails, please check whether the temperature affects the responsiveness of the screen.

If all else fails, you can attempt a factory reset.

Thank you.

Samsung Galaxy S4: Rings but caller/receiver can't hear:

Question: Was this phone paired with a Bluetooth device like a headset or to a car? It may be stuck to that..

In any case, try holding down the power button, select reset or power off, let the phone reboot. Then try calling someone or have someone call you to test. It should work..

If not, by default Google's "OK Google" voice search maybe the culprit. Try turning it off and see if that works..

"From the home screen, hold down the menu button which should go into Google Now. Click on menu button again and select settings. Select "VOICE." Then select "Ok Google" detection. Once there, switch off the option "From any Screen." Once that is turned off. Restart phone"

If this does not work for you, try calling your Cellular Service Provider and ask them to reset the connection on their side to your phone.,. While they do that, they may ask you to power off your phone, take out the battery, take out the SIM card, wait for at least 30 seconds before re-inserting your SIM card and battery, and then powering the phone back on

I had this happen on my Lumia 920 a lot. I pressed and held the power button till it finally rebooted. I seemed like it took a minute before it finally rebooted, so don't give up after 10-30 seconds. If that doesn't work try the power button and volume down button till it reboots. Some sites say this is a hard reset that wipes the phone, but as a last resort, I tried it when the power button alone wouldn't "wake it up". When it rebooted everything was normal, so either it isn't a "hard reset" or it doesn't do the "hard reset" when the phone is locked up and the screen is black. I never tried the power and volume down reset when the phone was operational, so I don't know.

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

This seemed to work for me;
1.) Reset the phones network settings
2.) Reboot the phone
3.) Put the phone in airplane mode
4.) Reboot the phone
5.) Take the phone out of airplane mode
6.) reboot the phone.
I read this on another website, and it seemed to work for me.
To reboot the iphone hold down the sleep/wake button, and the home button at the same time for 6 seconds (until the apple logo appears).
Good Luck!!

if not solved then go to www.htc.com for latest Rom update download and update backup ur data first


pls rate me fixya if i solved ur problem

I had the exact same problem and tried everything. It wasn't until I unplugged and main base from the electrical outlet for a few minutes and plugged it back in -- for some reason that made everything work. It is worth a try. We had some minor electrical outages in the last week due to weather so I assume that screwed something up.

i followed the advice posted & it worked fine after that. thanks.

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.

Your ringer has been switched off..to solve this press the menu button(mute in most of the sets)and press it until you see the option ringer press + to change it to off and then press menu again until you see the main screen...Thats all..
Let me know if it worked..
