MTR4bV2 4-Band Mountain Topper (NEW – Updated 1/12/21)
  • MTR4bV2 Supplement – Side Tone Adjustment – To adjust the side tone, use a NON-CONDUCTIVE or plastic screwdriver and adjust via the small access hole on the bottom of the enclosure. Adjust clockwise or counter clockwise to your personal preference. It is important to not use a metal or conductive screwdriver because you could miss the tuning adjustment and short out the PCB.
