Attaching the Unit
The Marlin unit attaches to the straps of your goggles. To
secure the unit, slide your goggle straps in the slits on each side
of the unit.
If your google straps do not fit in the slit, you may try stretching
the straps to make it fit in the slits. After the Marlin unit is
secured, you may wear your goggles as normal. Afterwards,
attach the bone conduction unit. Clip the bone conduction
unit to the side of your goggle straps as shown below.
Make sure the bone conduction unit makes contact with the
side of your ear as shown. When complete, insert the 3.5mm
side of the bone conduction unit to the Marlin unit. Please
note there is notch in the unit to ensure the connection is in
the correct orientation.
Device Basics
Device Sleep/Wakout
Marlin goes into sleep mode if it has not started for one
minute. When it sleeps, Marlin says Sleep.
To wake it up, push the START/STOP. When it wakes up,
Marlin says Wake Up.
Charging the Marlin
Before using the unit for the first time, we recommend charging the
battery in the MARLIN unit. Charging is performed by inserting the
3.5mm side of the charging cable into audio jack of the MARLIN unit
and the USB side to a USB port as shown below. There is notch in the
unit to ensure the connection is in the correct orientation. If charging
has started successfully, a red LED will start to blink. The LED will stop
blinking after the unit has been fully charged. The bone conduction
headset draws power from the MARLIN unit and does not need to be
charged.
Caring of the Marlin
Rinse the Marlin with fresh water after usage and store in a
cool and dry environment. Clear the headphone jack of water
before inserting the charge cable or the headset cable. Never
attempt to charge or connect while there is water in the
headphone jack. Do not use sharp objects to depress the
buttons as this may cause punctures to the buttons and cause
water damage. The Marlin is only designed to be used with
the provided cable and headsets. Usage of third party
headsets and cables are not recommended and will void the
warranty. Replacement for these accessories can be ordered
directly from Platysens. Do not use abrasive cleaners to clean
the Marlin. There are no user replaceable parts inside the
Marlin and all services should be performed by a manufacturer
specified agency or a qualified service personnel.

such scenarios, Marlin may guide you based on direction you
set during the swim.
In the App in Home->Open Water Mode->Options-
>Navigation, choose Navigate by Direction.
During you swim, push the START/STOP while swimming
toward your desired direction. Marlin would then say Direction
Set, and it would guide you to that direction.
