Using the device
Switching on / o
1. To turn on the devices, press their on/o buttons e. Channel indicators w will
now work as a charge indicator for one second:
If the charge state drops below approx. 10%, the RF status LED ring r ashes red
twice and the device shuts o automatically.
2. To charge the built-in battery, connect the micro-USB jack t. Use the supplied
USB cable with a powered-on computer or other USB charging source. During
charging, the RF status LED ring r lights red. When charging has nished, the RF
status LED ring r lights up blue. If the devices are not in use for a long time, fully
charge the batteries every three months.
Connecting and pairing devices
1. Plug the XLR socket of the transmitter into the XLR connector of the microphone.
Plug the XLR plug of the receiver into the XLR input of a mixer or similar device
for further signal processing (see the gure on the right).
2. After switching on both devices, they perform an automatic pairing and select
a suitable channel group. Wait until the RF status LED ring r of the transmitter
lights up blue. The pairing is now complete and the devices display the currently
used channel group.
To avoid interference, keep the devices at least 3 meters away from other trans-
mission equipment such as WiFi routers, etc.

Auto Standby
1. If the transmitter is not connected to a microphone 30 seconds after power is
turned on, or if the input signal remains o for 30 seconds, the transmitter and
the paired receiver automatically switch to standby mode to conserve battery
power. When the signal returns, both devices switch on again immediately.
2. If the transmitter is not connected to a micro-
phone for 1 hour after power is turned on, or
if the input signal remains o for 1 hour, both
devices will switch o completely. To turn them
back on, press the on/o button e of both units.
