How to fix Carmanah GPS light unresponsive to both pushbutton and radio commands?

  Cassandra BryantAug 16, 2025
  If your Carmanah GPS light isn't responding to either the push button or radio commands, it could be due to a few reasons: * The light may be in Infrared Mode. If so, toggle Infrared Mode off. * The light's battery might be low. Try charging the light. * The battery might have discharged beyond a critical low level. If the cells are lower than this, a Critical Low Battery Recovery may be attempted or alternately change the battery.
