Make sure that you have fully extended the FM antenna wire.
Make sure that you have installed batteries in the remote control handset.
Make sure that the system is connected to an AC outlet that is always "live".
Do not connect the system to an AC outlet controlled by a wall switch.
Most of the main functions of this system can be operated by the controls on the front
panel of the main unit, or by the buttons on the remote control.
If a specific function can only be operated by the remote control, or by the front panel
controls, this will be indicated in the instructions.
When operating this system with the remote control make sure that the IR (Infrared)
transmitter on the front of the remote control is pointed at the remote sensor on the front
panel of the main unit.
The effective operating range of the remote control is approximately 15 feet. Please
note that bright sunlight or room lighting may interfere with the remote control operation.
If the remote is not operating properly try reducing the brightness of the room or moving
closer to the main unit. If this does not solve the problem, it may be time to change
the remote control battery.
