This function enables you to the attenuate the RF signal at the antenna input. If the
receiver is used within approx. 65 feet (20 m) or less from the transmitter, we rec-
ommend activating the ATT function to make the system reliable and insensitive to
interference. With transmitter-to-receiver distances longer than approx. 65 feet (20
m), deactivate ATT in order to increase system range.
1. In SETUP mode, turn the jog switch CW or CCW a s many times as required to
display "ATT.OFF", and press the jog switch briefly.
2. Select "ATT.ON".
3. Press the jog switch to activate the RF Attenuation Pad.
1. In SETUP mode, turn the jog switch CW or CCW a s many times as required to

2. Select "ATT.OFF".
3. Press the jog switch to deactivate the RF Attenuation Pad.
• You can set the squelch threshold from -80 dB to -102 dB.
The hearing protection limiter places an absolute ceiling on the receiver output level.
Please note that the actual sound pressure at the ears will depend on the type of
earbuds used.
1. You can switch the limiter "ON" and "OFF".
2. To save your selection, press the Jog switch briefly.
• To avoid hearing damage, always leave the hearing protection limiter ON.
• The sensitivity of the human hearing system to aural stress differs from
person to person. Therefore, AKG will not assume any liability for any dam-
age to the user's hearing.
1. Set the receiver to STEREO or DUAL mode.
