10. A control device for controlling an electrical load, the control device comprising:
a base portion;
a control unit configured to be mounted over the base portion, the control unit comprising one or more light sources configured to be illuminated to indicate an amount of power delivered to the electrical load, and a control circuit configured to generate control data for controlling the amount of power delivered to the electrical load, the control circuit further configured to operate in a normal mode and a low battery mode;
a battery compartment configured to store a battery for powering the control device; and
a control unit removal device operable to release the control unit from the base portion to provide access to the battery compartment;
wherein, during the normal mode, the control circuit is configured to illuminate the one or more light sources to indicate the amount of power delivered to the electrical load; and
wherein, during the low battery mode, the control circuit is configured to stop indicating the amount of power delivered to the electrical load via the one or more light sources, and illuminate the one or more light sources to illuminate the control unit removal device to indicate the low battery condition.
11. The control device of claim 10 , wherein, during the low battery mode, the control circuit is configured to illuminate the control unit removal device in response to determining that the control device has been actuated.
12. The control device of claim 10 , wherein the control device further comprises a rotation portion for adjusting the amount of power delivered to the electrical load, wherein, during the low battery mode, the control circuit is configured to illuminate the control unit removal device in response to a rotational movement of the rotation portion.
13. The control device of claim 10 , wherein the control unit is configured to illuminate the control unit removal device to indicate a location of the control unit removal device.
14. The control device of claim 10 , wherein the control unit further comprises a light bar, and the control unit is configured to:
illuminate the one or more light sources to illuminate the light bar to indicate the amount of power delivered to the electrical load when the low battery condition is not detected; and
illuminate the one or more light sources to illuminate the light bar to indicate the low battery condition on the light bar.
15. The control device of claim 10 , wherein the control circuit further comprises a wireless communication circuit, and wherein, during the low battery mode, the control circuit is configured to cause the wireless communication circuit to transmit the control data to the electrical load when remaining power of the battery is above a threshold level, and stop causing the wireless communication circuit to transmit the control data to the electrical load when remaining power of the battery is below the threshold level.
16. A control device for controlling an electrical load, the control device comprising:
a base portion; and
