SNIP

According to the following, it's similar to the previous TM-271A

And there is a 271A Yahoo users group covering the 281A.

Hi,
I forgot to say in my post that I downloaded the TM-271A SM.
Unfortunately. the circuit board is much different than the TM-281A.
In the TM-271A, there is a place on the PCB where you use a tweezers or other
to short to "points", then turn on the power to enter adjustment mode..

Thanks again for your replies, John N3AOF
