How to Pair “Pairing” is the process that connects the speakerphone to your phone. You can pair more phones but can have only one active connection at a time.
  1. READY: Activate the Bluetooth feature on your phone, then use the phone’s settings to add/search/discover new Bluetooth devices.
  2. SET: First Time: With speakerphone turned off, activate Bluetooth pairing mode by pressing and holding the Multifunction button to turn on speakerphone. The LED flashes red/blue to indicate pairing mode.

  3. CONNECT: Select “PLT_K100” from the list of Bluetooth devices shown on your phone. If the phone asks for a passcode, enter four zeros (0000). Note: You may see **** on screen. Some phones also ask to confirm the connection after pairing. The speakerphone LED will stop flashing red/blue once your phone is successfully paired/connected.

How it works You can listen to calls through your car stereo speakers by transferring the audio from the speakerphone to one of five FM channel options:
  • 88.3MHz
  • 88.7MHz
  • 89.1MHz
  • 89.5MHz
  • 89.9MHz
If your phone is A2DP-enabled you can also hear streaming audio like GPS instructions and music through your car speakers. We recommend that you transfer audio to an FM channel before you start driving, and that you make a routinely clear channel a preset on your stereo.
Getting Started
  1. READY: Ensure that your phone and speakerphone are powered on and connected.
  2. SET: Press the FM button to enter FM transmit mode. The FM transmit channel will be announced.
  3. CONNECT: Manually set your radio to the announced FM channel. You are now ready to transmit calls and streaming audio like GPS directions from your phone to your car stereo. If a radio station suddenly takes over the FM channel, tap the FM button to quickly redirect the audio back through the speakerphone.

    To find another FM channel, while FM is turned on, press and hold the FM button until another channel option is announced, then tune your radio to the new channel.

This speakerphone announces various status alerts when you power on/off, run low on talk time, or lose/reconnect the Bluetooth connect ion to yout phone.

TIPS Keep Your Eyes on the Road: The controls are easy to find with your fingertips without looking for them. Before driving, reach up and familiarize yourself with the controls so you can keep your eyes on the road when a call comes in.
  • The notched Volume wheel is easy to feel.
  • The Multi-function button is inside the wheel.
  • The Mute button has a raised notch.
Avoid a Dead Battery: Remember to power off the speakerphone when you exit your car. If you forget, the speakerphone will automatically turn off after 90 minutes of not having an active connection. Protect Your Hearing: You can adjust the volume faster by turning the volume wheel faster. To adjust the volume a small amount, turn the wheel slowly. Turn the LED On or Off: For comfortable night driving, you can turn the lights on or off by pressing and holding the Mute button for 2 seconds until you hear a tone. Listen to the Voice: This speakerphone says various status alerts when you power on/off, lose/reconnect the Bluetooth connection to your phone, or change FM channels. Sound Your Best: Clip the speakerphone to your visor where the two microphones, located on the top of the unit, can be closest to your face so you can speak in a normal tone of voice and be heard.
