Reassembly Of Main Housing; Calibration; Setting The Date And Time; Calibrating The Pressure Sensor - VideoRay PRO 3 User Manual

5) A hair dryer may be used to aid in removal of the domes by warming the VideoRay housing and creating
a positive interior pressure.

REASSEMBLY OF MAIN HOUSING

1) Once the internal components have been properly re-installed in the main housing, the main ports can be
replaced. Care should be taken to ensure the ports are clean and dry and that the O-rings have been
cleaned and lubricated prior to installation. Refer to Section 8.3, Caring for Seals and O-Rings.
2) The tie-rods do not provide a means of sealing the main ports to the main housing. The O-ring seals on
the main ports that, in normal operation, are held in place by external pressure ensure the watertight
integrity of the main housing. The tie-rods are provided as a security measure, to prevent the main ports
from "popping out" in the event of a sudden over pressure inside the housing.
3) Re-assembly is accomplished by carefully fitting the main ports into the main housing and re-installing
the port retaining rings tie-rods, retaining nuts and washers.
Important: Avoid damage to the acrylic main ports. Do not over-tighten the tie-rod nuts.

CALIBRATION

Ensure that the Joystick and Depth Control knob are both in the neutral position before powering up the
VideoRay. This is critical, because their "zero" positions are calibrated when power is applied.
The additional VideoRay features that can set or calibrated include the date and time, the compass, and the
pressure sensor (which is used for determining depth). These features were calibrated at the factory and
should not require resetting. However, if maintenance work or electronics replacement should necessitate
recalibration, set your unit into calibration mode by turning it on while engaging the Mode switch to the
"Calibrate" position.
8.7.1

SETTING the DATE and TIME

Set the date and time by entering the calibration mode.
1) Turn the VideoRay off.
2) Turn the Video Ray on while engaging the Mode switch to "Calibrate."
3) Release the Mode switch.
4) The date and time are now shown on the display. Use the Auxiliary switch to adjust the values ("On"
to increase, "Off" to decrease), and engage the Mode switch to "Set" to store the new value and move
on to the next item.
5) To exit calibration mode, simply turn off the VideoRay. The new settings will be saved. Wait at least
5 seconds before turning the VideoRay back on. Or, to continue on to calibrate the pressure sensor
and/or compass, momentarily engage the Mode switch to "Calibrate," and follow the steps below.
8.7.2

CALIBRATING the PRESSURE SENSOR

This calibration is necessary when the pressure sensor is changed, or when a new control box is mated to a
submersible. This task requires an air pressure of 50 PSI (Pounds per Square Inch) be applied to the
pressure sensor. The Pro 3 toolkit includes a syringe with a pressure gauge for this purpose. If you are
setting the date and time or are calibrating the compass and do not need to reset the pressure sensor, BE
CERTAIN TO SKIP THIS PROCEDURE, so as not to disable the pressure sensor. Skip the pressure
sensor calibration by either turning the VideoRay off, or momentarily engaging the Mode switch to
"Calibrate" two times after setting the date and time.
1) Turn the VideoRay off.
2) Turn the VideoRay on while engaging the Mode switch to "Calibrate."
3) Release the Mode switch.
