BULLETIN # 58
MODEL: TR-2400
SUBJECT: TONE ENCODER RFI
In some cases, users may report RF interference, or motor-boating, when
using a tone encoder in their TR-2400. A secondary complaint of excessive
tone level may also be encountered.
1. For RFI, bypass the B+ terminal to ground with a 100 uf cap.
2. For excessive tone input to the TR-2400, install a 100 K ohm resistor
between the encoder and the TR-2400 Tone input terminal.
