OPERATION, CONTINUED
Pairing
The Bluetooth®Revo NC2™speaker microphone may be paired with a
compatible Bluetooth®-enabled two-way radio or mobile device. Once
connected, the microphone and speaker of the Bluetooth® Revo NC2™
will be available for use.
When successfully paired, the Bluetooth®Revo NC2™will remain
paired with the device, even when both the speaker microphone and
the paired device are powered down. There is no need to pair the two
again when powered back up.
Please note that Kenwood (except Viking VP series) radios have a
different pairing mode than other devices and require different pairing
methods on the Bluetooth Revo NC2™. The Kenwood-specic steps are
shown in italics below. Viking VP series radios are not subject to these
steps and must be paired in the same manner as all other devices.
1. To enable pairing mode, hold down the multi-function button
and the PTT button at the same time until you hear “Ready to
Pair” and the indicator light ashes red and blue continuously.
For Kenwood radios: Hold down the multi-function button
and the volume-down button at the same time until the Revo
NC2™enters pairing mode.
2. Follow the pairing instructions in the user guide for your
mobile phone or tablet or your Bluetooth®-enabled two-way
radio.
3. Select “OTTO_PTT_XXXX” in the pairing menu on your
device. The Xs represent the serial number of your specic
Bluetooth® Revo NC2™speaker microphone. Some devices,
including certain two-way radios do not have a display. Follow
the manufacturer’s guide to engage the pairing mode. If the

7
device does not have a display and multiple devices are being
paired with multiple speaker mics, only put one device into
pairing mode at a time to avoid pairing the Bluetooth Revo NC2™
with the wrong device. The speaker microphone will emit a tone
when pairing is successful and the blue light will ash 10 times.
4. Pairing mode will time out after 150 seconds if the unit is not
successfully paired with a device. Repeat steps 1-4 to attempt to
pair again. Kenwood radios: After “Connect” is chosen in the
radio menu to connect to the Bluetooth Revo NC2™, the radio
will “call” the microphone and ring tones will be heard on the
speaker mic. “Answer” the call by pressing the multi-function
button once and releasing, and the radio will complete the
connection to the Bluetooth Revo NC2™.
5. The Bluetooth®Revo NC2™speaker mic retains pairing
information for as many as six devices. Check the Bluetooth®
menu on the device to be sure the speaker microphone is paired
with the correct device.
6. Clearing the pairing memory is not essential, but it can be done as
desired. To clear the memory, perform the following operation:
• Press the multi-function button once and release.
• As soon as the blue/purple lights on the back of the speaker
mic light up (after approximately two seconds), press the PTT
button once and release. After a few seconds, a set of tones
will be heard. The memory has been cleared.
