How do I replace the clock backup battery?

1. Please make sure the AC adaptor is connected, otherwise all settings may be lost during battery replacement.
2. Use a Phillips screwdriver to remove the battery compartment cover located on the bottom of the unit.
3. Remove the depleted battery. Insert 1 CR2450 battery checking that the + side is facing you. Replace the compartment door. Do not over tighten.
