DVICE
:
If you are using the speaker for monitoring, instead of headphones, excessive advancement of the [AF
GAIN] knob can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up
in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at
all possible, or the minimum usable setting of the [AF GAIN] knob, if the speaker must be used.

Because the Monitor feature utilizes a sampling of the transmitter’s DSP signal, it can be very useful for
checking the adjustment of the Speech Processor or Microphone Equalizer on SSB, and for checking the
general signal quality on AM and FM.
