Helping You Get the Most From Your Hunting Dogs
How to Charge the SportDOG SD-1825 Collar Receiver
1. Obtain the Charging Cradle and put the Collar Receiver on it.
2. Behind the Charging Cradle, attach the charger connector.
3. Look for a 120-volt AC power source and plug the charger into it.
4. Charging time is two hours. This is applicable for the initial and the succeeding charges after that. The Collar Receiver utilizes a Li-Ion battery which needs to be charged for only two hours. Do not worry though if you charge it for more than two hours. This will not harm the unit.
Charge Cradle Indicator Lights:
When there is no collar receiver being charged but the charger is connected, you will see a solid GREEN light.
When the unit is charging, you will see a solid RED light.
When the unit is fully charged and the collar receiver is on the charging cradle, the GREEN light will flash one time per second once the battery is charged to its fullest.
