Navbow

The FREE is a low-speed gear with 1.0m/s, the SPORT is a medium-speed gear with l.5m/s the TURBO is a high-speed gear with 2.0m/s. The speed will be affected by different users,water temperature, depth, flow and other conditions, the increase of equipment mounting,the user's equipment, etc.

1. When navbow is not in use, take out the battery and store it separately. Battery storage temperature:25+5°c, humidity:65+25%RH. Maintain the power about 30-60%. Store it separately in a cool, dry and ventilated place.

2. A void direct sunlight and high temperature.The overheat battery may cause an explosion.

3. lf you store it for a long time, please check the battery capacity at least every 6 months, and charge it to 60%. 4. Please do not chargethe battery below 0°c.

5. Keep low power during transportation, discharge the power to30% before transportation.

This may be caused by long term exposure to moisture. Clean the electrode with dry clothand try to apply vaseline on the battery contact. If the corrosion is serious, please contact SUBLUE or authorized after-sales service center for support.

The battery: lithium-ion battery. Rated capacity: 10670mAh. Nominal voltage:14.8V.

Charging voltage:16.8v, Weight: approximately 1100g. Length:17lmm. Width:58mmThickness:60mm.

No, it is abnormal, the battery electrode should be free of corrosion or green stains. lf there is slight rust or stain, clean it with a dry cloth and try to apply vaseline on the battery contacts. lf the corrosion is serious, please contact SUBLUE or authorized after-sales service center for support.

The battery will always be in a deficient state due to not charged for a long time. When it is recharged, it may expand and deform. Long-term charging may also cause the battery drum to deform. Please store the battery separately in a cool, ventilated place with a temperature of 25+5° C, a humidity of65+25%RH. lf you store it for a long time, please check the battery capacity at least every 6 months and charge it to 60%.

You can contact SUBLUE or local dealer to purchase the spare battery.

Normally, the cycle charging times are around 300 times. As the increasing of charge and discharge, the maximum capacity of the battery will decrease.

The battery is a lithium-ion battery and will be heating under normal condition.

The battery is a lithium battery. In low temperature, the capacity will be sharply reduced.Please use it in 0°C-40°C. Do not charge or use it below 0°C.

Yes, it is normal. The battery is independently sealed. Navbow is a contact seal that only seals battery contacts and electrode copper. lf there is water on battery and electrode, please dry it with a clean dry cloth to avoid electrode corrosion.

It takes about 2.5 hours for 98Wh and 3.5 hours for 158Wh to fully charge the battery.

1.Input: AC 100-240V~50/60HZ

2.Output: Dc 16.8V

Please use navbow in open water area. lt is forbidden to use it in rivers, ponds or poor environment. Please pay attention not to let clothes, algae, ropes, shark nets, shells or other debris into the propeller.

Please contact SUBLUE or authorized after-sales service center for support.

No.First, navbow is battery contact sealing. Second, the circuit is low-voltage design and has circuit protection. This product has been tested and certified. You can use it safely.

Firstly confirm there is no foreian object in the propeller. The thrust is vary from high and low speed gear. Please choose the proper gear. The thrust is also affected by the using way,environment, user's height and weight.

If there is noise in the air, check the propeller for foreign objects. Be sure to follow the instructions for cleaning and maintenance after each use. If the noise is excessive, please contact SUBLUE or an authorized after-sales service center for support.

Please check if there are any foreign objects or blades in the propeller, or the front and rearprotective covers are damaged, etc. Or you can contact SUBLUE or authorized after-sales service center for support.

Please take out the battery, and open the front end cover. Take out the propeller to clean the windings. For details, please contact SUBLUE or authorized after-sales service center for support.

Yes. The motor will automatically stop due to overload protection.

Install the battery, and pushes the multi-function switch for ls. The OLED display lights up"SUBLUE" logo, then press the left and right buttons at the same time with both hands to go ahead.

Navbow is equipped with a dedicated charger. Please be sure to use the standard charger or optional fast charger. We will not be responsible for any damage of battery caused by other chargers.

Yes, it is.

Navbow is positive buoyancy in water and will not be sink or lost. However, if external deviceis added as well as influence water flow, it may become negative buovancy and will sink or even lose.lt is suggested that please wear anti-lost rope.

Turn on the multi-function switch, the OLED screen will show the left power.

Yes. Turn on the multi-function switch and press the start button to flexibly rotate the wrist and arm, For safety, please use it in shallow water and equip with life-saving equipment.People under age of 16 years should not use it.

The recommended temperature is 0-40 °C.Do not use it above 40°C

No. But we have reserved the interface for you, you can install a sports camera such as Gopro.

The size is 327mmx486mmx177cm (L*W*H)

The functions are setting of device information synchronization, self-cleaning, safety lockhand switching, etc.

There is a standard Gopro support under the front of Navbow, and a 1/4" underwater mounting hole on the top, for mounting of devices.

Yes. However, the micro-positive buoyancy is only in the case of sea/fresh water and user notadding negative buoyancy properties (such as weight, underwater camera, lighting, etc.).The water environment and extra mount will lead to buoyancy changing.

Scan the QR code in the user manual to download APP. Make sure your phone system is 10S10.3 or above system or Android4.3 and above.

Push forward the multi-function switch for ls. Then the OLED display lights up the"SUBLUE" logo and enters the main interface.

Push forward the multi-function switch for 3s, The OLED display turned off shows the machine.

There are three speed,"FREE", "SPORT", "TURBO". You can switch between three speeds.When the power is lower than 50%, please just switch between "FREE" and "SPORT".

There are two ways.

1.Push the multi-function switch for 0.5s and then release it.

2. Press the start button at the same time with both hands to keep the device running, release the right start button and click twice fastly (two time intervals of about 0.45s). This function is only valid in the two-hand mode.

When the power is less than two bars, the power icon on the screen will flash rapidly with vibrating three times. when the power is less than one bars, the power icon on the screen will flash rapidly with vibrating six times for the first time alarm.

First install a counterweight lif only one, place it in the middle hole), then completely sink the machine in the water and fully exhaust the air, check whether the buoyancy state is upto expectation. lf not, continue to increase the counterweight, Adiust three times until reaching your expction.

Yes, double-click the left start button twice when it is turned on and not running. One-handed operation requires additional accessories. The accessory needs to be purchased separately from SUBLUE.

Install D transfer buckle before launching-----+Connect one-handed lanyard-----+Connect the diving suit waist loop-Adjust to proper length according to arm length----+Startrunning with both hands after launching, then release one hand when the lanyard is straight and hand tension becomes smaller.

In safety lock mode, the machine cannot operate. The screen will display the safety lock icon.lf you want to operate the machine APP.
