Here are few possible causes and solutions to try if your wireless remote controller (9101A or 9101B) is not working properly with F One (F1) or F Two (F2) subwoofers.
Battery is low. Change new battery.
The remote control battery can be changed by turning the battery cover on the back of the remote control anticlockwise. Use a small screwdriver under the right side of the battery (see figure 5) to wedge the bat- tery out. Replace the battery with a similar CR2032 type battery. Insert the battery with the left side first as shown on the picture and close the battery cover.
The remote controller was unmatched with subwoofer. Try re-matching controller.
F One/Two (B):
1. Press and hold down the “Power” and “Select “ buttons on the subwoofer until the LED starts blinking white.
2. While the LED is blinking, first press and hold down the volume “+“ button on the remote control and then the volume “-“ button. Keep both buttons pressed for a few seconds until the status indicator LED on the subwoofer stops blinking. This indicates that matching is completed and the matching operation ends automatically.
F One/Two (A):
1. Disconnect the power supply from the mains connector for a moment and reconnect it or use the power switch to temporarily switch off the subwoofer. The white power indicator LED will start blinking indicating the seven second delay.
2. During the delay, first press and hold down the volume “+“ button on the remote control and then the volume “-“ button. Keep both buttons pressed for a few seconds until the power indicator LED on the subwoofer stops blinking. This indicates that matching is completed.
Controller is not reacting to volume buttons. HT mode is on.
In this mode the volume control of the F One or F Two does not have effect on the analog signals. Volume can be adjusted only on signal source. Turn off HT mode to enable volume adjustment using wireless remote controller.
Other wireless devices or obstacles are blocking the signal of the remote controller.
As wireless remote controller uses radio frequencies to communicate with the subwoofer, its functioning can be interfered by other devices that emit radio frequencies. These can be for example wireless routers. Try to move such devices and subwoofer further away from each others.
Solid obstacles like walls and furniture can block radio signals of the controller. Make sure that subwoofer and wireless controller has no obstacles between them to ensure proper working and best range of the controller.
