Our Thanks to You

Thank you for purchasing a CobraMarine Bluetooth Handset.
Properly used, this Cobra product will give you many years 
of reliable service.

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.

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.

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.

Connecting (Optional) to a Stereo System AUX Input

Telephone conversations can be switched from the internal speaker in the 

Bluetooth handset to the speakers that are part of the boat’s stereo system.

1. Connect the external stereo system to the handset connector cord 

with a 3.5 mm male stereo jack. This cable is not supplied but can be 

found at your local audio/visual store.

USB Connector

The USB connector shown next to the external stereo jack is used to 

connect to a personal computer (PC) to reprogram or update the software 

in the Bluetooth handset. The latest software and update instructions can 

be found at www.cobra.com.

Installation

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.

1. Drill a hole through the bulkhead or dash in the chosen location 7/8 inches for a

thick dash or 5/8 inches for a thin dash.

2. Install the components as shown in the diagram.

If the dash is thin enough, the flange can be at the back surface of the dash and the

threads project out the front. If the dash is thick, the threaded part of the Male

Bulkhead Connector will project through the Mounting Plate and the hole in the dash

will be big enough for the flange at the base of the threads to be right up behind the

Mounting Plate.

Installing the Hanger Bracket

1. Install the hanger bracket on a vertical surface 

near the bulkhead connector using the supplied 

stainless steel screws.

Getting Started

Common MR F300 Functions

Getting Started

Refer to the foldout at the front of this manual to identify the various controls and

indicators on your Bluetooth handset.

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.

When using the handset, tones will sound to:

Indicate an error – three beeps.

Confirm an action – two beeps.

Confirm a single button press (except the PTT button) – one beep.

You can turn the Key Tones Off if you want (see page 22). 

Try It Out

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.

Common MR F300 Functions

The following procedures define common operating functions of the handset.

Power On/Off

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.

Mode

This button serves two functions:

To change the mode of operation between the Bluetooth handset and 

your cell phone itself.

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. 

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.

Common MR F300 Functions

Push to Talk (PTT)

This button serves two functions:

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.

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.

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.

To Make a PA Announcement:

1. When the unit is in Standby mode, press the PTT button and talk into the

microphone.

NOTE

Before a PA announcement can be made:

The PA function must be turned ON from the settings menu.

The F300 must be connected to the stereo system AUX input.

The stereo must be in AUX mode with the stereo’s volume adjusted.

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.

Red Phone Button

This button acts just like the red phone button on a cell phone. Pressing the button

ends an active call.

In modes other than an active call, it backs up to the Standby mode.

Common MR F300 Functions

VOX

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.

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.

NOTE

When the VOX function is On in noisy environments, the caller connected 

to the F300 might hear some of your background noise. 

Back Light/Lock

This button serves two functions:

To turn the display back light On and Off.

To lock and unlock most of the buttons on the handset.

Back Light

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.

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.

To Turn Lock On or Off:

1. Press and hold the Back Light/Lock button for two seconds.

Maintenance

Very little maintenance is required to keep your CobraMarine Bluetooth handset in good

operating condition:

Keep the handset clean by wiping with a soft cloth and mild detergent. Do not use solvents

or harsh or abrasive cleaners, which could damage the case or scratch the LCD screen.

If the handset is exposed to salt water, wipe with a soft, moist cloth at least once a day to

prevent buildup of salt deposits, which could interfere with button operation.

To determine the software version in your handset, press and hold the PTT button

while turning On the power. The version number will show on the LCD screen for 

five seconds, then proceed to normal startup.

The USB connector on the bulkhead connector cord can be used to update the

software for your handset using a personal computer. Go to Cobra’s website

www.cobra.com to find the latest software version and follow the instructions there.
