Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The Model Number of the phone system you are working with? That model should be printed on a sticker on the bottom or back of the main base unit and START with KX-TG, followed by a 4-digit number. (the number you sent (KX-TGA470) is for one of the cordless handsets.
2) How many TOTAL cordless handsets do you have with this system?
3) What phone service provider (phone company) you have for this phone line?
4) When you say "intermittent flasher on the telephone's remote control", what exactly are you referring to?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
