EPO or CPE Expired Error on a Garmin Dog Tracking Handheld
Extended Prediction Orbit (EPO) or Connected Predictive Ephemeris (CPE) files allow Alpha® dog tracking handhelds to predict where satellites will be in the sky, which reduces GPS acquisition time. With updated EPO or CPE files, instead of taking 2-3 minutes to find GPS signals, it will usually take less than 30 seconds.
If the handheld has not been used in over 30 days or has traveled more than 200 miles since its last satellite connection, the EPO or CPE data can expire.
Updating the EPO or CPE Data
Satellite location information is refreshed periodically when your Garmin product syncs data with an Garmin Explore™ or Alpha® app account. Garmin products can be synced with the Garmin Express™ program, the Garmin Explore app, or the Alpha app to update their EPO or CPE data. To determine which applications will work with your device and how to sync, refer to the sections below:

How Do I Check EPO or CPE Status?
EPO or CPE status can be checked under About in the System or Setup menu of your Garmin product. EPO and CPE files expire, and are usually only good for a range of 3-14 days. Sync the dog tracking handheld regularly to download new EPO or CPE data. Refer to your owner's manual for help finding the About menu of your device.
