Connecting the VLC 302 Charger and Charging the Microphones

NOTE: The charging station is to be used with NiMH rechargeable batteries only.

To connect the charger and charge the microphone(s):

1. Connect the 5 VDC, 2.6 A wall charger (with USB Mini-B adapter) to a 110-130 VAC (US) or a 100-240 VAC (international), 50-60 Hz power source.

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 green when the microphone is fully charged.

NOTE: Microphones can be left to charge for extended periods.

• In Student mode, all buttons are disabled except for power. Set the dip switch to the ON (up) position to enable “student” mode.

3. Apply the appropriate label (provided) to identify the microphone (see 3 at right).

4. To wear as a pendant microphone:

a. Push the lanyard into the guides on the lanyard lock.

b. Open the microphone clip.

c. Slide up the lanyard lock under the clip, then release the clip.

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

A at 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 B in 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 B at 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 first 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.
