The answering machine/wireless landline phone began to make loud crackling noises both in the handset and the answering machine. It has worked well for a year or two and nothing happened to make it start the noise. I just hate to throw it in the landfill if it can be fixed.

I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck

hello there, when you say warm how warm do you mean? secondly is the phone located near a window or a place where the room temperature could cause the handset to be warm? finally how long have you been using the phone? these are in relation to the temperature.
What kind of noise do you hear in the background? Can you please give a simulation of what the sound is like?
Hoping to hear from you.
