Turn the TI-UMX2 on and off using the switch located on the bottom right corner of
the keypad. When TI-UMX2 is initially turned on, a TI-UMX2 logo will be displayed,
accompanied฀by฀lots฀of฀lashing฀led฀lights.฀The฀TI-UMX2฀will฀attempt฀to฀‘auto฀identify’฀
the฀transducer฀type฀that฀is฀connected,฀or฀display฀‘NO฀PRB’฀if฀the฀transducer฀cannot฀be฀
identified. The following sections outline each scenario. Note: This section is primarily
written as a basic startup guide only.
3.1 TI-uMx2 displays
The TI-UMX2 is equipped with two segmented LCD displays that are used for entirely
different purposes. The 6 Character display above, is used for all the menu options and
any text to control the overall operation and functionality of the TI-UMX2. Since the
TI-UMX2 has the ability to store measurements, this display is also used to view and
move฀to฀speciic฀cell/storage฀locations฀in฀the฀grid฀storage฀structure฀of฀the฀gauge.
noTe: The฀left฀most฀‘comma’฀located฀in฀the฀top฀left฀corner฀of฀the฀display,฀identiies฀
which sub menu feature option is currently selected, as shown above. In this example
the gain is currently set to medium.
The 4 digit display illustrated above, is considered the primary measurement display of
the TI-UMX2. The following outlines the measurement display:

14.0 Care & MaInTenanCe
The TI-UMX2 housing is made of a clear PVC material that is very durable and well
suited for this application given the following conditions are followed:
•฀฀ Keep฀the฀TI-UMX2฀out฀of฀direct฀sunlight฀as฀much฀as฀possible฀to฀avoid฀any฀potential฀
‘crazing’฀or฀stress฀cracking,฀as฀well฀as฀discoloration.
•฀฀ Protect฀the฀housing฀from฀impact.
•฀฀ Submerge฀or฀rinse฀the฀enclosure฀and฀transducers฀in฀fresh฀water฀following฀use.
•฀฀ WarnInG: Do not exceed the depth limitation of 1000 ft. Failure adhere to this
warning may result in leakage, potential implosion and serious injury.
The housing is sealed by o-rings, one on each end cap, which require meticulous care. In
order to maintain a watertight seal, the o-rings and their mating surfaces must be clean,
free of foreign material, and lubricated with silicone grease.
IMPorTanT: The following procedure must be performed on the end cap o-rings
before each use:
1. Clean all old silicone grease from o-rings and mating surfaces using paper towels.
2. Inspect o-rings for foreign material (sand, seaweed, hair, etc.), cracks, cuts, soft
spots, or deformities. Replace o-ring if damaged. Inspect mating surfaces for
scratches, rough spots, dents, or cracks.
3. Apply thin, even coat of silicone grease to o-rings on each end cap using finger to
spread evenly. Inspect to be sure the o-ring has been properly fitted, and screw the
end cap back in place, until it has a nice snug fit.
