quencies in MHz as they are scanned.

and the message "READY" appears on the display. If no interference frequen-
cies were found, the display will change to "CLEAN".

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.
2. In STEREO mode, you can set the balance between the left and right audio
channels. The display will indicate the volume of the louder channel (L or R) in
12 increments.
"L R 00" means the volume of both channels is the same.
In DUAL mode, you can set the balance between channel 1 ("CH1") and chan-
nel 2 ("CH2"). The display will indicate the volume of the louder channel in 12
increments.
"CH- 00" means the volume of both channels is the same.
3. To save your selection, press the Jog switch briefly.
• You can call up the balance screen even in LOCK mode by pressing the Jog
switch briefly. You can set and save the balance between the left and right chan-
nels or channels 1 and 2. However, you cannot toggle between STEREO and
DUAL modes.
