I have 2 cordless Bell Studio 2008/167 phones (duo set) but the 2nd phone doesn't work. When plugged & with full battery, it dies when I take it out to make or answer a call. I noticed the batteries had "leaked" so I replaced them with brand new ones after cleaning the phone with a dry cloth. Now, the phone gives me a "battery warning" message & I can not do anything with the phone. The network & phone icons flash, but that's it. Pls help, thanks
