LEAK TEST:
Before utilizing the system for the first time, it is highly recommended to perform a 'Leak Test’. Follow
the instructions below, but DO NOT INSTALL THE MP3 PLAYER inside the housing for the leak test.
1. Visually inspect the main housing seal by opening the unit. Verify the seal is seated as intended
and the O-ring is clean of any artifacts, then close and lock the housing using the OPEN-CLOSE Dial.
2. Make a first dive to your intended depth, taking the housing and speakers only (NO MP3).
3. During this dive, manipulate the controls at various depths.
4. After surfacing, check inside the housing for any sign of leaks.
5. Only after a successful Leak Test, install the MP3 player in the housing.
6. If you are not diving, but using the system in a wet environment, first immerse the housing, without
the MP3 player, in a tank of water to (1 meter or 3 feet if possible) and manipulate the controls. Then
check for any signs of leakage.

O-RING PREPARATION:
1. Gently Remove the O-ring with the Remover. Be careful not to stretch the O-ring
CAUTION: Never use a sharp or metal object to remove O-rings as they damage the O-ring or the O-ring
groove contact surface. Use only the O-ring Remover Tool included in the packaging.
2. Check the O-ring for hair, sand, lint, or other debris and wipe clean as necessary. Be
careful not to stretch the O-ring. If the O-ring is cut or cracked it must be removed and
replaced with a new O-ring.
3. Wash your hands prior to greasing the O-ring. Grease the O-ring using your fingertips.
Uniformly spread a bead of grease on the O-ring until there is a thin film covering the
complete surface. Do not stretch the O-ring. CAUTION: Only use the O-ring grease provided with
your housing.
4. Before replacing the O-ring, visually inspect the groove in the lid and the contact surface
for hair, sand, lint, or other debris and wipe clean as necessary. Also, check the contact
surfaces scratches, blemishes, or other imperfections. If an O-ring contact surface is
damaged, do not use the housing. It is very possible the housing will flood and damage the
electronics. Contact your dealer for advice.
5. Install the O-ring with the flat side down; making sure that it is seated uniformly, with no
twists or loose areas. Be careful not to stretch the O-ring unnecessarily.
GENERAL STORAGE PROCEDURES:
For long-term storage, remove O-ring and store out of direct sunlight. If the O-ring will not be used for a
long period of time, remove from it the housing and store in a plastic bag out of direct sunlight. If the O-
ring is stored in a dry environment for a long period of time, it will develop cracks and become unusable.
CAUTION: The life of an O-ring is typically one (1) year. Contact your supplier for spare O-Rings or a
maintenance kit. Always remember to reinstall and lubricate the main housing O-ring before next use.
Do not expose the housing to extreme heat, such as the inside of a hot car, or in hot direct sunlight, such
as a beach, or boat deck. Doing so may cause damage and subsequent flooding.
CAUTION: Do not store housing in following environments:
* High humidity
* Solvents or other chemical fumes
* High Ozone
* Extreme temperature fluctuations
Storage in such conditions may lead to housing damage and leakage.
Rinse the EXTERIOR of the system in fresh water after EACH use:
1. Make sure the housing is sealed and closed
2. Soak in clean fresh water for 30 minutes.
3. Rinse the entire system with freshwater
4. Then completely dry the entire exterior of the system using a clean soft cloth.
Strong detergents, soaps, and chemicals MUST NEVER be used to clean the system. If you must use a
soap, it should be a very diluted.

INSTALLING & REPLACING AMPLIFIER BATTERY:
STEP 1: WIPE EXTERIOR AND MAKE SURE IT IS DRY
STEP 2: TURN OFF THE AMPLIFIER
STEP 3: OPEN HOUSING
CAUTION: Completely dry the
inside of any moisture
STEP 4: REMOVE AND UNPLUG THE MP3 PLAYER
INSTALLING THE MP3 PLAYER:
CAUTION: Before opening be sure to rinse the sealed system in fresh water. Before installing the MP3
player, make sure the housing interior is dry. Moisture in the housing can cause damage to the electronics.
STEP 1: DRY THE EXTERIOR
STEP 2: OPEN HOUSING
Note: Use a soft clean cloth. NEVER
use direct heat
STEP 3: PLUG STEREO ADAPTER
INTO MP3 PLAYER
NOTE: Some MP3 players have two audio jacks.
Make sure you plug the adapter into the
HEADPHONE audio jack
STEP 4: PLACE THE MP3 PLAYER IN THE
HOUSING
NOTE: Use the buttons on the side of the player
to guide the unit into place
STEP 5: CLOSE THE LID
Begin to close the lid by bringing it down towards the housing. Make sure the Lever
Controls are lined up with the Joysticks on the MP3 Player.
CAUTION: Make sure the lid is free of any lint, hair, sand, or other items. DO
NOT FORCE THE LID CLOSED. If you feel resistance, check to make sure
the MP3 player is seated correctly. Rotate the OPEN/CLOSE Dial
CLOCKWISE until the front and rear halves of the housing are fully closed,
then push in the small locking tab on the dial.
STEP 6: SEAL CHECK
Manipulate each of the housing
controls. Check that they are aligned
with and are properly contacting the
MP3 player controls.
Make sure the O-ring is partially squeezed, sealing the gap between the
housing front and rear halves. If this contact line is not uniform, there is
a good chance the housing will flood. Therefore, open the housing,
reseat the O-ring and/or remove the contaminants as necessary.
CAUTION: If you cannot manipulate all of the controls with the housing, go back to step 1 above and start again. This is
important because it could mean the MP3 Player is not seated properly in the housing, or the housing controls are out of
the position, which could cause water leakage and damage.

player installed correctly by following the steps outlined above.
