You may select the locking schemes via the menu item
"Lock Mode".
You may reduce the receiving signal strength to 20 dB when extremely strong local signals or high noise
degrade reception. You may optimize the characteristics of the receiver front-end, for best reception,
depending on the noise levels and the signal strengths.
Press the [ ATT] button several times to set the desired
selection.

ignition systems.
