- Short R500 (470R) SMD (increase TXD to heads).
- Change R545 (47K) to 10K SMD (increase RXD drive into radio).
NOTE: Max 50R wire resistance in TXD/RXD/Data lines).
- T2020/T2050: Short R644 (1M0) SMD out (increase Beep level).
T2040: Short R618 (1M0) SMD out.
- Change R658 (150K) to 82K SMD (2nd. mic. audio I/P).
