Getting Started

When you buy the Dolphin the battery is disconnected and needs to be charged, follow the instructions on page 9, Battery Use, Charging the Battery, for charging and connection.

Using the DOLPHIN for swimming and snorkeling.

When swimming or snorkeling the Dolphin should be kept positively buoyant-this is done by simply making sure the Buoyancy Chamber is empty and fitted inside the Nose Cone.To use the Dolphin for swimming or snorkeling follow these instructions.1.    Charge the battery-see page 9 for instructions(make sure that when you finish charging the Vent Plug is closed).

2.    Place the Dolphin into the water so the Handle, Outer Nose Cone and Nozzle fill with water.

3.    When ready to set off, switch the Master Switch to the On position shown in figure 2.

4.    Pull and hold the Trigger to start the Propeller.(There is a short delay before the Propeller begins to rotate).

5.    To stop the Propeller, simply release the Trigger.

6.    Always turn the Master Switch off when out of the water.

Proper posture when using the DOLPHIN is important to achieve the maximum speed-see figure 3 for the correct position of the DOLPHIN when using it.

Using the Dolphin for diving-adjusting the buoyancy.

Your Dolphin can be used for diving up to 65ft/20m but will need to be adjusted for neutral buoyancy. The olphin must never be adjusted for negative buoyancy to avoid it sinking if accidentally released.

To adjust for neutral buoyancy follow these instructions

1.    Make sure the Dolphin is in the Off position.

2.    Remove the Dolphin from the water, give a half turn to the Latches, remove them(see figure 4 ) and remove the Buoyancy Control Chamber.

3.    Replace the Outer Nose Cone and Latches.

4.    Place the Dolphin in the water to fill the Nozzle, Handle and Outer Nose Cone with water.

5.    Remove the lid form the Buoyancy Control Chamber and place the upturned chamber on the Handle as show in figure 5.

6.    Adjust the buoyancy by adding stones and replace the lid of the Buoyancy Chamber making sure the seal is free from sand.

7.    Remove the Dolphin from the water, remove the Outer Nose Cone again, replace the Buoyancy Chamber, replace the Outer Nose Cone and close with the Latches.

Battery Use 

Charging the battery

For battery charging follow these instruction.

1.    Always ensure that the Master Switch is Off-see figure 2.

2.    Always ensure that the Dolphin is out of the water and placed in a dry area.

3.    Give a half turn to the Latches and remove them from the Nose Cone as shown in figure 4.

4.    Remove the Outer Nose Cone and Buoyancy Control Chamber.

5.    Open the Vent by unscrewing the Vent Plug.

6.    Remove the Inner Nose Cone. To do this, first feed the silicone ring( provided with this manual) through the latch holes in the Inner Nose Cone and hook over the hooks on the Battery Housing(see figure 6 ). Then screw the Pump Nozzle onto the Vent Hole and pump air into the Battery Chamber until the Inner Nose Cone pops off and then remove the silicone ring.

7.    Allow two minutes for any gasses to dissipate.

8.    Disconnect the battery cable from the housing cable (if not already disconnected-the cable will be disconnected when you buy your Dolphin) by pressing the locking feature, as shown in figure 7.

9.    Connect the battery cable to the charger cable.

10.Plug charger into mains, and turn on the supply. Do not replace the Nose Cone.

11.Charging will take 4 to 6 hours for a fully discharged battery. Flashing light indicates battery is fully charged.

Unplug the adapter from the mains.

13.Unplug the battery cable from the charger cable and reconnect to the housing cable.

14.Make sure the seals and sealing surfaces are clean and lubricated before replacing the Inner Nose Cone. See figure 8.

15.Replace the Inner Nose Cone making sure the key is aligned correctly. See figure 9.

Ensure the Vent Ring is fitted correctly. See figure 10.

Screw in the Vent Plug to seal the vent.

Replace the Buoyancy Control Chamber.

19.Replace the Outer Nose Cone making sure the key is aligned correctly and insert the Latches and lock the Nose Cone by giving them a half turn. See figure 11.

Note: To charge a battery outside of the unit, simply connect to the charger, then plug the charging adapter into the mains.

When the battery is charged, unplug the adapter first then the battery.

To replace a flat battery with a fully charged battery.

1.    Follow the steps 1 to 6 on page 10, to open the Dolphin.

2.    Unplug the battery at the socket by pressing the locking feature shown in figure 7.

3.    Remove the flat battery, remove the cables from the flat battery and fix them to the charged battery.

4.    Install and connect the charged battery in the correct position-the leads of the standard or extended life battery must be oriented as shown on the sticker on the battery, see figure 12.

5.    Follow steps 14 to 19 on page 12, to close the Dolphin.

Using the Optional Extended Life Battery.

An optional extended life battery is available through your dealer. This battery fits into the Battery Housing in a slightly battery for correct orientation, see figure 13.

The extended battery can be charged in the same way as a standard battery.

Sand or Grit on Seals

Sand or grit is the enemy of seals. Correct maintenance and care is essential. To remove sand or grit from the seals, rinse the seals in fresh water and apply fresh lubricant. If there is sand inside the Battery Housing, gently brush the sand from the unit taking care not to scratch the sealing surfaces. 

DOLPHIN cuts out

To protect the electronic circuit of your Dolphin from damage a safety mechanism has been built in that cuts the power if a wall or rock or other immovable object is hit. If this occurs simply wait for a short period to allow the Dolphin to reset itself and resume use.
