I have the ET-732 that is probably 5 years old or so. Went to use it today and batteries were dead so I replaced them. Unit powered up but non of the front buttons work any more. I can't set temps, turn on/off, etc. Are there transceivers available or do I need to buy an entire new unit? IF I need to purchase a new unit, what is the new popular model now?
