Limiter
This feature can be used in order to provide audio lim-
iting at the receiver in order to prevent excessive levels 
at the headphones or earbuds. To set the amount of 
limiting, highlight “Limiter” in the menu list using the ar-
rowkeys.Press“MENU/SEL”tochoosethisfunction.
Use the arrow keys to select the limiter threshold in 
3dB increments. Test it with a known signal to deter-
mine the maximum sound level you are comfortable 
with. The pre-gain setting can then be used to boost 
the audio level before the limiter. Use this feature if you 
need to make up for a weaker signal at the transmitter. 
UsetheMENU/SELbuttontochoose“Pre-Gain”,then
use the arrow buttons to adjust in 3 dB increments.
Backlight
The backlight control page allows you to select the 
length of time before the backlight turns off on the re-
ceiver. The factory default setting is 5 minutes, but you 
can also select 30 seconds or “Always on.”
Treble Shelf
In this screen, you can choose a treble boost with a 
corner either at 5kHz or 7kHz, and a boost of up to 
9dB in 3dB increments. This feature can be used to 
overcome a stereo mix without enough high frequency 
information, or earbuds that “roll off” too early in the 
high frequency area.
This high-frequency boost should be used sparingly 
due to the fact that it can accelerate hearing loss with 
high volumes in the earphones or headphones. Note: 
the factory default setting is 5 kHz corner with 0dB 
boost.
Lock Setup
This feature is used to lock the control panel so that 
no further changes can be made. Once “Locked” is se-
lected, note that a small lock icon is at the upper right 
ofeachsetupmenuscreen.Withthereceiverlocked,
you can view each menu screen but you are unable to 
make changes and the power can not be turned off.
To return to the unlocked status, go back to the “Lock 
Setup” screen via the main menu, and select “Un-
locked”. Also, note that the “Locked” status is main-
tained even if the batteries are changed.
Factory Default
This is used if you intend to reset the receiver to all the 
factory default settings.
