2. Connect the USB mini plug end of the adapter to the USB mini jack located
on the back of the VLC 302.
NOTE: The charger can also be powered by a USB source using a mini
USB cable.
3. If required, unscrew and remove the microphone battery cover to install the
battery. Insert the battery, aligning the + and – poles as indicated inside the
compartment.
CAUTION: Do not replace the batteries with an incorrect type. Use
only rechargeable batteries specified or provided by Extron, or alkaline
batteries.
ATTENTION:
• Do not attempt to charge alkaline batteries.
• Be sure to replace the battery with the correct type and to dispose
of used batteries appropriately.
4. Insert the microphone into one of the charger slots.
The microphone LED turns red to indicate charging, and

Pairing with the VLR 302 Receiver
Each VoiceLift kit includes VLP 302/VLH 302 microphones and VLR 302 receivers that have already been paired. If needed, follow
the steps below to pair microphones with a receiver.
Verify which Microphones are Paired
1. Ensure that the microphones are fully charged. Power each microphone on, one at a
time, to determine if the microphones are paired to the VLR 302 receiver.
NOTES:
• As each microphone is powered on, one of the VLR link slot LEDs (see
Aat right) will illuminate if the microphone is paired.
• Only one microphone can be paired to each LINK slot on the VLR
receiver.
2. Once you have determined which microphones are paired, turn them off.
Pair New Microphones
Follow these steps to pair microphones to the VLR 302 receiver.
NOTE: All paired microphones must be turned off before pairing new microphones.
1. Press and hold the LINK button on the VLR 302 receiver (see Bin the image above) for 4 seconds to start pairing mode.
If LINK slots are available, one of the LINK LEDs blinks to indicate that pairing mode has started.
NOTES:
• Once initiated, pairing mode is enabled for 30 seconds. Users must repeat the process if they have exceeded the 30
second pairing window or if pairing was not successful.
• Receiver Pairing/Discovery mode can also be enabled remotely via SIS comands. Commands can be sent to the
receiver through direct USB connection or through PVS switcher connection.
2. Follow the steps below for your microphone model:
• For the VLP 302:
Ensure that the microphone is powered off.
NOTE: The VLP microphone must be in “TEACHER”
(off) mode in order to pair.
Then, press and hold the POWER and FUNCTION buttons
(see A and Bat right) simultaneously for 4 seconds until
the status LED blinks red and green, indicating pairing mode
has started.
• For the VLH 302:
Ensure that the microphone is powered on.
NOTE: The VLH microphone must be in “STUDENT”
(on) mode in order to pair.
Then, press and hold the LINK button, located beneath the battery cover (see C at right), for
4 seconds.
The microphone status LED changes from solid amber to alternating red and green, indicating that pairing mode has
started.
NOTE: The receiver assigns the microphone to the rst available LINK slot. If the microphone is paired successfully,
one of the LINK LEDs on the VLR receiver lights solid green.
3. After pairing the microphones, verify that they have been set up properly as shown in the previous section, Setting up the
Microphones, on the previous page.
