Increasing the Battery Life of a Dog Collar Using an Astro 220

Garmin dog collars broadcast their position to the Astro® 220 dog tracking handheld at certain time intervals. The battery life of the collar can be lengthened by decreasing how often the collar position is updated with the handheld. In order to adjust the update rate, the handheld and dog collar will need to be paired and within close proximity of each other.

To adjust the update rate on the Astro 220 handheld:

  1. Power On the device and collar
  2. Press Dog button
  3. Press Menu
  4. Select Dog List
  5. Select your dog collar
  6. Select Show Info
  7. Press Menu
  8. Select Change Comm. Settings
  9. Select OK to confirm ID channel
  10. Highlight the position update rate
  11. Press Enter
  12. Select a slower update rate
  13. Select OK to confirm update rate
  14. Select OK to confirm changes

Your dog tracking collar will now update its position less frequently, increasing the battery life.
