CONNECT TO YOUR PHONE

PLT_ M155

“Pairing” is the set-up process of
introducing your headset to your
phone. Before using your headset
for the first time, you must pair it
with your Bluetooth-enabled phone.

“Multipoint” lets you pair this
headset with two phones so you can
answer a call from either phone.

1. READY

First Time, Right Out of the Box:

Put on the headset and slide
power switch to turn it on. The
LED flashes red/white to indicate
pairing mode.

Pair New or Second Phone:

Turn on headset. Press Call
button until the LED flashes red/
white for pairing mode.

2. SET

Activate the Bluetooth feature
on your phone, then use phone
menus to “add,” “search” or “scan”
new Bluetooth devices.

Phones Have Different Menus to
Select from, for example:

iPhone: Settings > General >
Bluetooth > On (starts the search
for devices)

®

BlackBerry
Settings/options > Bluetooth: On >
Search for devices

Android
Settings > Wireless & Networks >
Bluetooth: On > Scan for devices

smartphone:

3. CONNECT

Select “PLT_M155” from the list of
Bluetooth devices shown on your
phone.

If phone asks for a passcode, enter
four zeros (0000). You may see ****
on screen.

Some phones also ask to confirm
headset connection after pairing.

Headset LED will stop flashing red/
blue once successfully paired/
connected.

You can now make a call using your
phone’s keypad or voice-dialing
feature.

FIND YOUR FIT

The loop of the gel eartip tucks into the back
curve of your ear for a stable fit.

Try on the headset. The eartip is positioned to
suit most people, but you may want to rotate it
to best fit your left or right ear.

To remove the eartip, pull the loop of the eartip
away from the speaker stem. (Don’t pull on the
speaker base and stem.)

Tuck the bottom of the new eartip over the
speaker and pull the eartip over the speaker.
(Don’t push the speaker through the gel eartip.)

If the gel eartip feels loose or tight in your ear,
then replace it with one of the two alternate
size eartips.

TIPS

Stay Near Your Phone

Bluetooth has a working “range” of up to 33
feet between the phone and headset before
audio degrades and the connection is lost.

Know How to Reconnect

Your headset tries to reconnect a lost connec­tion. If it can’t, then tap the Call button once or
manually reconnect via the phone’s Bluetooth
device menu.

Use Multipoint One Call at a Time

Once you have activated multipoint and paired
your two phones, it’s easy to answer calls from
either phone.

When already on a call, you will hear a ringtone
notification of the incoming call from the
second paired phone.

Play Tunes and Take Calls

If you are listening to any streaming audio
when your phone rings, the audio will pause
to allow you to answer or ignore the incoming
call. Once the call ends or is ignored, the
streaming audio resumes playback.

Use Your Voice

After being prompted by the headset, you can
just say “answer” or “ignore” to incoming calls ­no need to press any buttons.

You can disable this voice-controlled feature.
With the headset powered on, simultaneously
press the call button and vol button until you
see the white LED flash twice. To reactivate the
feature, just repeat the steps and you will again
see the white LED flash twice.

To answer a second call from the other phone,
you must end the current call (tap Call button)
so new call automatically answers.

If you choose not to answer the second call, it
will go to voicemail.
