Owner’s Manual  
How Your CobraMarine Bluetooth Handset Works  
This handset allows use of mobile telephones (cell phones) afloat while protecting  
them from potential damage in the marine environment.  
Bluetooth wireless technology allows voice and data transmission over short  
distances by means of a radio link. Using that technology, the Bluetooth handset  
allows your cell phone to be turned on and stowed in a waterproof and protected  
location on the vessel. Calls are then made and received using the Bluetooth  
handset on deck or in the cabin of your boat.

Introduction

Important Safety Information  
Recommendations for Marine Communication  
The U.S. Coast Guard does not endorse cellular telephones as substitutes for marine  
radios. They generally cannot communicate with rescue vessels and, if you make a  
distress call on a cellular telephone, only the party you call will be able to hear you.  
Additionally, cellular telephones may have limited coverage over water and can be  
hard to locate. If you do not know where you are, the Coast Guard will have difficulty  
finding you if you are using a cellular telephone.  
However, cellular telephones can have a place onboard where cellular coverage is  
available – to allow social conversations and keep the marine frequencies uncluttered  
and available for their intended use.  
Before installing and using your Bluetooth handset, please read these general  
precautions and warnings.  
Warning and Notice Statements  
To make the most of this Bluetooth handset, it must be installed and used properly.  
Please read the installation and operating instructions carefully before installing and  
using the handset. Special attention must be paid to the WARNING and NOTICE  
statements in this manual.  
WARNING  
Statements identify conditions that could result in personal injury or loss of life.  
Included in this Package  
You should find all of the following items in the package with your CobraMarine  
Bluetooth handset.  
NOTICE  
Statements identify conditions that could cause damage to the handset,  
other equipment or stored data.

Connecting Power to the Bulkhead Connector Cord  
Your Bluetooth handset is powered from your vessel’s 13.8 volt DC system  
(12 volt nominal). A fused power connection lead is provided at the opposite  
end from the bulkhead connector fitting.  
1. Attach the black wire to a negative ground.  
2. Attach the fused red power wire to the positive side of the vessel’s  
12 volt DC power system.  
Before using your Bluetooth handset, the bulkhead connector cord must be  
installed on your vessel and connected to a 12 volt DC power source.  
Installing the Bulkhead Connector Cord  
Choose a convenient location for the connector near where the Bluetooth handset  
will be used. Keep in mind that the nine foot long coiled cord on the handset must  
be attached to the connector when the handset is to be used.  
Connecting to the Bulkhead Connector Cord  
1. Drill a hole through the bulkhead or dash in the chosen location 7/8 inches for a  
Red  
thick dash or 5/8 inches for a thin dash.

Getting Started  
Common MR F300 Functions  
Refer to the foldout at the front of this manual to identify the various controls and  
indicators on your Bluetooth handset.  
The following procedures define common operating functions of the handset.  
Power On/Off  
Most button functions are activated by a momentary press, then release. In those  
cases that call for “press and hold,” hold the button down for at least two seconds  
after it is pressed. The PTT button is held down as long as you are speaking into  
the microphone.  
Press the Power button at the top of the handset for two seconds to turn it On  
or Off.  
The first time you turn On the CobraMarine Bluetooth handset you will see a  
message that the unit is ready for pairing with a cell phone. The message also  
provides a password. If you do not want to pair a device right away, press the  
Escape button to go to Standby mode.  
When the unit is subsequently turned On, it will search for the currently selected  
Bluetooth device and go to Standby mode.  
When using the handset, tones will sound to:  
I
Indicate an error – three beeps.  
I
Confirm an action – two beeps.  
I
Confirm a single button press (except the PTT button) – one beep.  
You can turn the Key Tones Off if you want (see page 22).  
Mode  
Try It Out  
This button serves two functions:  
I
Using the Bluetooth handset is the most effective way to learn about it. Don’t  
hesitate to explore functions and add entries to see how they work. Do not be  
concerned if you make mistakes. They can all be undone in Edit mode. Or you  
can reset the unit to the original factory default condition. Push and hold the  
Green Phone and Home function keys, then push the Power key until the  
unit turns On.  
To change the mode of operation between the Bluetooth handset and  
your cell phone itself.  
I
To switch voice activation of the microphone between On and Off. Turn VOX On  
if you want to operate in a hands-free mode similar to a Bluetooth handset.  
Mode  
Normal operation of the CobraMarine Bluetooth handset uses its internal  
microphone and speaker to conduct conversations during a call. However,  
there may be times you want to suspend the Bluetooth pairing and continue  
part or all of the call on your cell phone itself.  
NOTICE  
Resetting the unit will clear ALL Bluetooth device pairings as well as the  
Call Log, Phonebook and Bluetooth device list.  
To Change Between Handset and Cell Phone Modes:  
1. Press the Mode button to switch the call to your cell phone.  
2. Talk and listen to your cell phone in the usual way. The handset will be inactive.  
3. Press the Mode button to restore operation to the handset.  
4. Talk and listen to the call on the Bluetooth handset.

VOX  
Push to Talk (PTT)  
The VOX function converts the handset microphone’s pickup of your voice from  
being controlled by the PTT button to being activated by your voice. When VOX  
is On, the PTT button does not need to be pushed to transmit your voice and  
you can just speak into the microphone.  
This button serves two functions:  
I
To activate the handset microphone during a call when VOX is Off. This is similar  
to the action of such a button on a CobraMarine VHF or a CB radio.  
I
To activate the handset microphone for a PA announcement, the unit must be in  
Standby and be connected to the stereo’s AUX input with the stereo in AUX mode.  
When VOX is Off, you need to push the PTT button while speaking.  
To Change Between VOX On and Off:  
1. Press and hold the Mode button for two seconds while a call is in progress.  
To Activate the Handset Microphone During a Call:  
1. After placing or accepting a call, press the PTT button and talk into the handset  
microphone.  
NOTE  
When the VOX function is On in noisy environments, the caller connected  
to the F300 might hear some of your background noise.  
To Make a PA Announcement:  
1. When the unit is in Standby mode, press the PTT button and talk into the  
microphone.

I
The stereo must be in AUX mode with the stereo’s volume adjusted.  
A light is provided behind the LCD screen to improve visibility of the information  
provided there. However, you can turn the light On or Off at will.  
Green Phone Button  
This button acts just like the green phone button on a cell phone. Pressing the  
button answers an incoming call and initiates dialing an outbound call after the  
number has been entered or selected.  
In Standby mode, this button is a shortcut to the Call Log where a number can be  
selected to call.  
To Turn the Back Light On or Off:  
1. Press the Back Light/Lock button.  
Lock  
The Lock function disables the operation of all buttons except PTT, Back Light/Lock  
and Power buttons. When Lock is On, accidental presses of any of the other buttons  
are ignored by the unit. A call can be continued if it was started before Lock was  
turned On, but new calls cannot be made or answered when Lock is On.  
Red Phone Button  
This button acts just like the red phone button on a cell phone. Pressing the button  
ends an active call.  
To Turn Lock On or Off:  
1. Press and hold the Back Light/Lock button for two seconds.  
In modes other than an active call, it backs up to the Standby mode.
