Cleaning the Sensor

DO NOT CONTACT CLEAN SENSOR UNLESS ABSOLUTELY NECESSARY.

Identifying Debris

Debris on the image sensor or optical components will appear as a darkened area or smudge on the image that does not move as the camera is moved. Do not confuse this with a pixel defect which will appear as a distinct point.

Locating Debris

Before attempting to clean the image sensor, it is important to first determine that the problem is due to debris on the sensor window. To do this you should be viewing a uniform image, such as a piece of paper, with the camera. Debris will appear as a dark spot or dark region that does not move as the camera is moved. To determine that the debris is not on the camera lens, rotate the lens independent of the camera. If the spot moves as the lens moves, then the object is on the lens -not on the image sensor- and therefore cleaning is not required. If the camera has an IR filter, then rotate the IR filter. If the object moves then the particle is on the IR filter not the sensor. If this is the case remove the IR filter carefully using a small flat head screw driver. Clean both sides of the IR filter using the same techniques as explained below for the sensor window.

DO NOT TOUCH ANY OPTICS WITH FINGERS. OIL FROM FINGERS CAN DAMAGE FRAGILE OPTICAL COATINGS.

Cleaning with Air

If it is determined that debris is on the sensor window, then remove the camera lens, and blow the sensor window directly with clean compressed air. If canned air is used, do not shake or tilt the can prior to blowing the sensor. View a live image with the camera after blowing. If the debris is still there, repeat this process. Repeat the process a number of times with increased intensity until it is determined that the particulate cannot be dislodged. If this is the case then proceed to the contact cleaning technique.

Contact Cleaning

Only use this method as a last resort. Use 99% laboratory quality isopropyl alcohol and clean cotton swabs. Dampen the swab in the alcohol and gently wipe the sensor in a single stroke. Do not reuse the same swab. Do not wipe the sensor if the sensor and swab are both dry. You must wipe the sensor quickly after immersion in the alcohol, or glue from the swab will contaminate the sensor window. Repeat this process until the debris is gone. If this process fails to remove the debris, then contact AVT Canada Inc.

GX3300C, GX3300 specifications

The Allied International GX3300 and GX3300C are versatile marine radios that bring a wealth of features and advanced technology to ensure seamless communication on the water. Designed with both recreational and professional mariners in mind, these devices enhance safety and connectivity through a user-friendly interface and robust functionality.

One of the standout features of the GX3300 series is its dual watch function, which allows users to monitor two channels simultaneously. This is particularly useful for navigating busy waterways or when keeping an ear on emergency frequencies. The radios come equipped with a powerful 25W output, ensuring clear communication over long distances.

Both models incorporate digital selective calling (DSC) capabilities, enabling users to send distress signals and communicate with nearby vessels or coast guards at the touch of a button. The internal GPS receiver is another significant attribute, providing precise location data that ensures mariners can share their position during emergencies or routine communication. This integration of GPS simplifies the process of relaying information verbally, as the device will automatically transmit the vessel's coordinates.

The GX3300C model goes a step further by including a built-in AIS (Automatic Identification System) receiver. This crucial feature allows mariners to receive information about nearby vessels, enhancing situational awareness and safety, especially in congested waters. AIS data displays the position, course, and speed of nearby ships, which aids in collision avoidance and navigation planning.

Both models feature a clear, backlit LCD screen that guarantees visibility under various lighting conditions. The intuitive controls and menu navigation make operating the radios straightforward, even for less tech-savvy users. The rugged design of the GX3300 series ensures durability against harsh marine environments, with water and shock resistance being key characteristics.

Additionally, these radios support an extensive range of frequencies, allowing for worldwide marine communication. With built-in weather channels, users can stay informed about changing weather conditions, which is crucial for safe navigation.

Overall, the Allied International GX3300 and GX3300C radios combine advanced communication technologies with practical features to enhance marine safety and connectivity. Their reliable performance and user-friendly design make them essential tools for anyone operating on the water, ensuring that help is always just a call away.
