Reactivating after T-Storm

I have a TRU9485 Approximately 2 years old. Have the base and 4 separate handsets. We had a thunder storm last night and none of them work now. I have 2 "plug in" phones and they work fine. I've unplugged the base and all 4 chargers plug them all back in but still doesn't work. I would appreciate some help with this problem.

    Thanks for replying to my request for help. I have a health monitor (I've fallen and can't get up). My base and answering machine have to "go through" it. When I called that company they had me turn that monitor off and then on again and everything works the way it is supposed to.

    Thanks again,

    Jo Murdock

What kind of problems do you help with? I have a couple of little things could use some help with. I am not a computer whiz but I consider myself to be moderately experienced. Since I'm not sure what kind of problems you help resolve I'll wait until I hear from you to post another problem. It just dawned on me, I have "met" you from a "phone" website and my problems have nothing to do with phones, it's all computer.

How do I turn the answering systyen on & off

You can do this from the base or the handset with the unit in standby mode (not being used for a call or access other menus).

From the base press the Answering Machine On button (at the bottom right of the keypad on the base).

From the handset, press the message softkey (this is the right softkey). Remote Answering Machine Operation will show up on the screen and the unit will announce the time and number of messages (new and old). Press 9 during the announcement. You will hear Answering System is On and the current greeting.

The owner's guide is available here: . See page 57.

I hope this helps.

Phone message reads

If you are not too far away-not "out of range" then try rehoming/pairing the handset with the base unit. You probably need the phones together to do this. Your manual will explain how-it will have been done in the original setup.

Reset base unit of Uniden TRU9485

Uniden TRU9485 (This didn’t work for me but this was the first instruction from Uniden Tech Support)

Unplug the base unit AC adapter.
Hold down for 15 seconds the DND, * and “menu” soft key (the middle silver soft key under the LCD) while plugging the base unit AC adapter back in.
All the settings should be reset.

Uniden TRU9485 (Worked for me)

Unplug the base unit AC adapter.
Hold down for 15 seconds the DELETE KEY (zero with a line through it) while plugging base unit AC adapter back in.
All the settings should be reset.

Problem Siemens Gigaset 4000 and 4200

If you had a storm, and the only handset that works shows line in use, then your base has gone bad and needs repair. The reason the phones are flashing base 1 or something to that effect is because they don't see the base anymore, which typically means no phones will see your base, so its odd that one phone is actually seeing the base. Either way, you can try re-registering the phones to the base, but if you get the line in use after they register (if they will register), then your base is bad. If they won't register, your base is bad. For additional assistance you can go to

1 handset "no link to base', picked up a new one but the de-re register procedure did not work, still have the same msg with the new handset

You may have a bad base. Do you have other handsets that are running okay on your base? Are you confident your going through the registration procedures correctly with the replacement handset? Did you have a storm come through preceeding your problems?

My siemens gigaset 4215 and 4000 don't work and need some kind of code whats the code?

Hello, Almost never is it the handset that is bad when those symptoms occur. It sounds as if your base has gotten hit by a power surge and won't boot (the handset now can't "talk to" the base and its always searching for it). Most people report this after a storm has passed through their area. You can try re-registering the handset to the base, but unfortunately it probably won't work, sorry. You can order the base only and register your handset to the replacement base when you get it. To order a replacement base using google, search for Siemens Cordless Repair and click the first non sponsored link. Good Luck

You can connect up to 4 cordless sets (Operating manuals, page 21, states 3 but they really mean 3 in addition to the one packed with the base, for a total of 4). I've head four connected for over 5 years now and they work fine. In your case, try disconnecting the battery of the cordless for at least 30 seconds, then reconnect. You may also want to disconnect the power cable from the base unit for a half minute or so. I found this method to be equivalent to a cold boot, and quite effective in getting all phones to work again after a storm or power outage.
