1. Press the Volume button once to check the volume
  2. Press the Volume button again within 2 seconds to increase the volume--A special tone is played at max volume and a step past max volume returns the volume to the minimum level

Additional Notes

  • When checking the volume, the number of the lit LED segments shows the volume level and a tone will play at the present level
  • The volume adjustment works in a cycle as opposed to being able to go up and down independently
