Power ON/OFF:
ON：push once to turn on.
OFF：push and hold until ''Power OFF'' is shown on the LCD to turn o.
EXIT: Push exit to cancel a selection or exit from the current menu when RU-
901Du is in the ''setting menu.''
Rotary Switch: when in the ''function menu,'' turn the switch to select the
desired function; push the switch (or SETUP) to enter the selection and spin the
switch to select the setting. Push [SETUP] to save the setting.
SETUP: Push and hold for 2 seconds to enter the“setting menu.”Push SETUP to
save the setting once the selection and setting are made according to
''3. Rotary Switch.''
:this allows user to synchronize the transmitter after modifying a
parameter. Push “ ” to synchronize the settings to the transmitter.
Remoset indicator: this shows the current pairing status. It ashes rapidly
when data is being transmitted and the ashing stops when the synchronization
is completed. However, the ashing slows down if synchronization fails after a
period of time of pairing attempt.
Ultrasonic transmission unit: it transmits digital pairing data at ultrasonic fre-
quency. When setting, direct the ultrasonic receiving element of the microphone
to the ultrasonic transmitting unit of the receivers. The eective range is 30º on
both sides with the optimized distance at 30cm.
LCD display: See ''Receiver LCD display instructions.''
AF: indicates the current strength of audio frequency signals.
RF: indicates the current strength of radio frequency signals.
Key lock: push and hold for 2 seconds to lock all keys, and again to unlock.
Volume keys: push▲/▼keys to adjust the volume between 0 and -31dB.
Selection key: push this button
a. Push SETUP to enter the setting for the selected channel for parameter
settings.
b. Push REMOSET to transmit the setting data to the transmitter in this
