ADS-SR1 not recognizing all DTMF codes

#1
all that seems to be recognized by the unit is 0 for repeat, nothing else. Never get tone responses. I power cycle the unit in case there is a timeout specified, nothing seems to work. Unit repeats fine and audio is clear, but the DTMF functions do not respond. I am using an FT70D and have no issues with DTMF with other devices.

Try to adjust the volume level up and down to find the sweet spot. Then mark it for further reference.
