Battery backup function:
1. When power to the unit is interrupted, the internal power supply will be switched to battery backup mode
immediately. The LED backlight is also disabled.
2. The battery backup feature also allows the user to program the unit without having it plugged into an outlet. You
can change the settings while holding the unit in your hands which is more convenient than crouching down to
reach a wall outlet.
3. Do not leave the unit unplugged with batteries installed for an extended period. Otherwise the batteries will be
exhausted prematurely. When the unit is plugged back in or AC power is restored, the internal power supply will
be switched back to AC line power.
4. To replace the battery: Using the small Philips style screwdriver open the battery holder, and position the 3 (AAA)
batteries, ensuring polarity is correct. When the batteries are in place, press the battery holder back into its
original position and use the screwdriver to secure.
