Figure 33: Mute Adjust Menu.
The default Mute Adjustment range is from 0 – 15. The mute adjustment setting will
be applied to all the radio’s analogue channels.
The SDP600 series radios have a carrier noise mute and it is recommended that a
default mute setting of 4 is used. This means that, with a setting of 4, the mute will
open at the point where an analogue signal is sufficiently noise free to be intelligible.
Other settings are as follows:
• 0 No muting. Allows all decodable signals to the radio user’s audio output device
(loudspeaker, headset etc.).
• 4 Normal default setting.
• 8 Only reasonably strong signals will be heard.
• 15 Only very strong or near perfect signals will be heard.
Use the

selected mute setting and return to the previous menu level.
Direct access to the ‘Mute Adjust’ screen from other screens can also be programmed
to one of the function buttons with the FPP.
