Dark: The transmitter is in SILENT mode.
2 Display: The transmitter provides a five-line display:
Alphanumeric display of

or battery capacity in hours
Battery capacity
or audio level bar graph
The display indicates all transmitter parameters:
- Carrier frequency in MHz or as a Channel of a Frequency Group
- Audio input level
- Battery status and remaining operating time
- Error messages
- Setup menus: Frequency, Preset, Gain
The backlighting of the display comes on every time you actuate the setup switch and
will switch off after approximately 10 seconds.
3 ON/OFF button: A short push (approx. 0.6 seconds) will switch power to the transmit-
ter ON and activate the display (2) and status LED (1). The transmitter will be ready to
operate after approx. 7 seconds.
A long push (approx. 2 seconds) will switch power to the transmitter OFF.
The ON/OFF button is recessed for protection from unintentional actuation.
4 MUTE switch: Sliding the MUTE switch toward the outside of the transmitter (arrow)
will mute the audio signal. The status LED (1) will change to red. Since power and the
RF section remain ON, no unwanted noise will become audible from the sound system
when you mute the audio signal.
To switch the audio signal back on, slide the MUTE switch toward the inside of the trans-
mitter (toward the ON/OFF switch). The status LED (1) will change to green.
The MUTE switch is active in all modes.
5 Charging contacts: The recessed charging contacts allow you to recharge the optional
AKG BP 4000 battery pack on the optional CU 4000 charger without having to remove
the battery pack from the transmitter.
6 Setup switch: Sets the various parameters of the transmitter. The setup switch has the
following functions:
• LOCK mode:
Turn left or right briefly to scroll between Frequency, Preset (only if a Preset has been
loaded), Gain, and Battery Capacity (shown in hours) screens.
Long push: toggles between LOCK and ACTIVE modes when the transmitter is ON.
When power to the transmitter is OFF, a long push switches the transmitter ON and
places it in SILENT mode.
• ACTIVE and SILENT modes only:
Short push: calls up a parameter for adjustment or confirms a selected value.
