Using Cross Remote
The unit is equipped with a wireless remote control function that allows the unit’s settings (low-cut filter, attenuation controls, power controls, etc.) to be controlled from the receiver or other devices. This makes it easier to operate and manage the microphone system while in the field.
The IEEE802.15.4-compliant wireless remote control function uses the 2.4- GHz band and has no effect on the RF band of digital wireless audio.
The function is activated when the unit is paired with the receiver via the RF REMOTE function.
Pairing must be performed before the wireless remote control function can be used.
Notes
If “RESTRICTED BY GP/CH SETTING” appears on the RF REMOTE screen, the wireless remote control function cannot be used. To enable use of the wireless remote control function, select a different transmission channel.
For details on changing the transmission channel, see “Setting the Transmission Channel” (page 7).
Pairing
Pairing links the unit to the receiver that will control the unit via the wireless remote control function.
Pairing will start automatically if pairing mode is enabled on the receiver side and you turn on the unit by holding down the POWER button while pressing the – button on the unit.
To perform pairing manually via the settings menu, perform the following.
1 Enable paring mode on the receiver that will be controlling the unit.
For details, refer to the receiver’s operating instructions.
2 Use the + and – buttons to display the RF REMOTE screen.
3 Hold down the SET button until the setting value blinks.
4 Use the + and – buttons to select PAIRING.
5 Press the SET button to confirm.
The unit sends a pairing request to the receiver on which pairing mode is enabled.
If you press any button on the unit before pairing is complete, pairing mode will be canceled.
When communication with the receiver is established, the condition indicator (
) rises, indicating that the
RF REMOTE function is enabled and remote control is possible.
Using Cross Remote with a previous pairing setting
