Choose the mounting location carefully—before you drill or cut. The display screen is high-contrast and anti-reflective, and is viewable in direct sunlight, but for best results, install the 957 out of direct sunlight. See the figure below for additional mounting recommendations. - Page 11 SECTION TWO: Installing and wiring the 957 Regardless of the type of mounting, the 957 should be installed in an accessible location (dry) where the operator can easily use the controls and clearly see the display screen. Be sure to leave a direct path for all of the cables.
- Page 12 CAUTION! When flush mounting, be sure to mount the 957 on a flat surface. Mounting on a curved surface can break or distort the plastic and break the waterproof seal.

- Page 39 Figure 14: Satellites on the GPS satellites screen The satellite map on the GPS SATELLITES screen shows the current location of the satellites in the sky. The 957 displays GPS satellites as circles; WAAS satellites as hexagons. You can check the quality of their signals by looking at each satellite’s Signal-to-Noise Ratio (SNR).
- Page 40 You can override the auto-dim function at any time by increasing the brightness with the BRIGHTNESS key. The 957 may dim again as required so as not to exceed the maximum internal temperature.
