2 Description
Refer to fig. 1.
- approximately 60 minutes before the batteries or BP 4000 battery pack wil be dead;
and
- while the transmitter recalls the carrier frequency from memory after you turned
power to the transmitter on. Unless you muted the audio signal, the status LED will
change to green as soon as the frequency has been recalled.
- while the display shows an error message.
Dark: The transmitter is in SILENT mode.
2 Display: The transmitter provides a five-line display:
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 Audio input: 3-pin mini XLR connector with both mic and line level pins that automat-
ically match the connector pinout of the recommended AKG microphones or optional
MKG L instrument cable.
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.
