How the Housing Sentry-Complete Works
|Using the Housing Sentry-Complete is simple and adds very little time or steps to your pre-dive routine. Set up your camera and housing as normal.|
|Once your camera is in place and the housing is closed, remove the block-off plug from the vacuum connector.|
|Insert the input fitting on the pump hose into the vacuum connector and start using your pump to create a vacuum. This will activate the electronics of the Housing Sentry-Complete.|
|When the vacuum reaches about two inHg, the red LEDs will begin blinking at a fast rate.|
|The rate will slow when the vacuum reaches six inHg.|
|The red LEDs will stop flashing and the green LEDs will begin to slowly blink when the vacuum reaches ten inHg.|
|Stop pumping when the green LEDs light. Remove the input fitting from the vacuum connector and insert the block-off plug.|
The housing should be allowed to set for at least fifteen minutes before beginning a dive. If the green LEDs are flashing after the fifteen minutes have elapsed, your system is ready to go. You may do a normal leak-check dunk in the camera bucket or just get started diving.
During your dive, the Housing Sentry-Complete will give you regular feedback with the flashing green LEDs so you know the vacuum is intact. Should the vacuum level drop, you will be alerted with the flashing of the red LEDs. This can be seen in the video below.
At the end of the dive, rinse your housing as normal. You may leave the Housing Sentry activated if you are planning to use the exact set-up (no battery, memory, lens or port change) on your next dive.
|If you need to make a change to the set-up, first remove the block-off plug from the vacuum connector. Then, if you have the manual pump, connect the pump by inserting the input fitting into the vacuum connector and release the vacuum by pressing the vacuum release lever on the pump.|
|If you are using the rechargeable pump, remove the hose from the pump and connect the hose to the vacuum connector by inserting the input fitting. As soon as the fitting is connected, the vacuum will be relieved.|
You can open your housing as normal once the vacuum has been released.
