kxt-7453 and 7456, can you turn the back light off or will it stay on even when phone is on hook?
Thank you!
I think it depends on what you have it connected to. In the TDA you have a few settings regarding backlighting. I'm not sure if they apply to the 7400 series phones.
On the TD's the backlight stays on even when idle.
I Haven't seen one but looking it up it said there is a 3 position switch for off-low-high
look at the back of phone, should be a small switch to control the back light.
Yes, on the 7400 series there is a small switch behind the display that can be turned off.

As an aside, I had an issue with a 7730 that was in a bedroom. At night the backlight on the display was like a spotlight. It lit the entire room! I opened up the set and played around with various values of serries reistors in the lead to the backlight. I was able to get the display to a very low brightness that didn't light the room, but still plenty bright to see the display in the dark.
Board level alterations may be a bit more in depth then a lot of us feel comfortable with

7400 series will not work with a tda. Just the 7600's.
Wow, don't tell that to my TDA-200 on a customer site. They might quit working :-)

Reataylor,
I have 7400's working on TDA 50's and 100's. They do draw more power, so it's important to use the correct power supply.

thats funny did you read that in the install manual?
ReaTaylor, I don't know who told you that but
for the record
All of the TDA series support
the 7000, 7200, 7300,7400 and 7600 series of phone sets or PITS.
You do need the proper cards and power supplies.

hey G have you tried a kx-t 123230 to see if it
would come up on a hybrid port?
No, I haven't and can't forsee me trying that in the future as if the system is that old they can upgrade the phones as well. :toothy:
MrG
Believe it or not I used that model for all
kx-t and td quick setups.
