eStudio 250 Fax Module Tx Attenuation Adjustment

[Clif]

Hello

How do I adjust Tx line attenuation on a eStudio 250 fax module. I assume service mode is 1 & 3 power on. Mr Spock would know this

Thanks

FUNC 4 Bits 7 to 4:
The bit settings allow the user to program the modem transmission attenuation level. The smaller the
set value, the higher the transmission level becomes. If errors occur frequently or training is not sent,
the transmission level should be changed, as a rule.
