IMPORTANT
Batteries are required to maintain time and date
in the event of a power loss.
Use two AA alkaline batteries; nonalkaline batteries do not
last as long. We recommend Energizer® batteries.
1. Use a coin to remove the battery door (see Fig. 5).
2. Install the fresh batteries, as shown, making sure the
positive and negative terminals are oriented
correctly (see Fig. 6).
3. Replace the battery door.
