Electronic Thermal Throttle®

Your Eclipse LD may be equipped with Electronic Thermal 
Throttle (ETT), a highly useful and unique feature available 
on Bullard firefighting Thermal Imagers. The ETT is ideal 
for pinpointing hot spots during overhaul, searching for 
overheated electrical equipment, or clarifying objects in 
ambient temperature situations. To activate the ETT option, 
locate the rubber cover on the top of the Eclipse LD. Press 
the left side of the cover, which is the left button on the 
throttle, to activate the ETT (Figure 4). The ETT will automatically sense the hottest 
area in the scene and color it blue. Additional presses of the left button will further 
engage ETT and will color more of the scene blue, eventually coloring even the coolest 
objects blue.

NOTE

As the throttle engages more of the scene, the blue will become lighter in hue to 
help differentiate objects in the scene.

As you cycle through the scene, you’ll see the symbol “TT” and a corresponding 
number in the upper left hand corner of the display. The “TT” indicates “Thermal 
Throttle” mode. The number (0-99) is a point of reference to indicate the level of 
Thermal Throttle engagement; by itself it has no specific meaning. Most of the benefits 
of the ETT are accomplished with the first few presses of the button. To deactivate the 
ETT or lessen the amount of blue in the scene, press the right side of the cover, which 
is the right button on the throttle. Alternatively, you can quickly deactivate the ETT, by 
pressing both buttons simultaneously for one second or turning off the Eclipse LD and 
turning it back on.

 CAUTION

The Eclipse LD Thermal Imager is extremely sensitive to intense, radiant heat 
sources. Never point the Eclipse LD at the sun or any other source of extreme 
radiant heat, as this could severely damage the thermal imager.

Custom Startup Graphic

Via myBullard, you can customize the startup graphic which appears when you first 
power on your Eclipse LD. To upload your own image and change the startup graphic 
on your Eclipse LD, go to myBullard and select the Eclipse LD module. You will see a 
selection for customizing the startup graphic. Follow the instructions in myBullard to 
upload a new graphic and change it on your Eclipse LD.

SceneCatcher Digital Video Recorder

Your Eclipse LD may be equipped with Bullard’s SceneCatcher digital video recording 
accessory. For the Eclipse LD, the SceneCatcher is installed inside the thermal imager 
so there are no external attachments. To activate the SceneCatcher, locate the rubber 
cover on the top of the Eclipse LD. Press and hold the right side of the cover until the 
red dot appears in the upper left hand corner of the Eclipse LD display. When the red 
dot is visible on the display, you are recording video to the unit’s internal memory. To 
deactivate the SceneCatcher, press and hold the right side of the cover until the red dot 
disappears.

Loading/Unloading a Battery

To load a battery (Figure 5), depress and then slide the battery release switch in the 
direction of the arrow indicated on the button. With the 
battery release switch engaged, slide the battery into the 
groove in the cavity located at the bottom of the unit. You 
will hear an audible “click” when the battery is properly 
seated. To unload a battery, depress and then slide the 
battery release switch in the direction of the arrow 
indicated on the switch. With the battery release switch 
engaged, grip the battery by its exposed bottom section 
and pull it away from the unit (Figure 5).

 NOTE

If the battery is inserted without first retracting the battery release switch, the 
battery will not fully seat. If this occurs, remove the battery and follow reload 
using the instructions above. 
The battery latch mechanism prevents accidental battery release upon impact.

Charging and Maintaining 

Batteries

If you purchased an Eclipse LD Powerhouse with your 
Eclipse LD Thermal Imager, see the enclosed Powerhouse 
manual for charging instructions. If you purchased an 
Eclipse LD Thermal Imager only, you received a charging 
base. 
To charge a battery in the charger included with your Eclipse LD, place it in the charging 
base (Figure 6). A steady red light will indicate that the battery is charging, while a 
steady green light will indicate a full charge. The system will detect the full charge and 
will not overcharge the battery. A completely drained battery takes up to three hours to 
fully recharge.
As with all batteries, your Bullard rechargeable battery will experience a slow drain 
of its charge during storage. The amount of drain varies widely based on storage 
conditions. To ensure adequate battery life, charge each of your batteries every two 
weeks or, for best performance, keep your Eclipse LD and spare battery charged 
in your vehicle in the Eclipse LD Powerhouse truck mount charger accessory (part 
number: ECLPOWERHOUSE). If you are using a Powerhouse charger, follow the 
instructions contained in the accompanying manual.

 WARNING

Do not allow the metal contacts on the battery to come in contact with a 
conductive surface, such as a metal table or another battery. While the Eclipse LD  
battery is equipped with protective circuitry to prevent product damage, contact 
with conductive surfaces can complete the battery circuit and cause the battery 
to overheat or melt. Failure to observe this warning may result in permanent 
battery damage, property damage and/or serious injury.

 

NOTE

New, fully charged NiMH batteries will provide a run time of more than two 
hours. To extend the potential lifespan of your batteries, fully drain and recharge 
each battery monthly. For best operational results, develop a clear formalized 
plan for maintaining, charging, and replacing your batteries.

Retractable Strap

The Eclipse LD Thermal Imager fits easily into a turnout gear pocket for convenient 
storage while crawling or working. Additionally, Bullard offers a retractable strap that 
can be used with the Eclipse LD, so that it is always at the ready. The strap, purchased 
separately, can be mounted to a D-ring on your turnout gear coat and connected to the 
D-ring on the Eclipse LD.

Care Instructions

The Bullard Eclipse LD Thermal Imager requires little maintenance. For best results, 
after each use:

•  Clean the outside of the unit with mild soap or detergent.
•  Wipe the lens with a soft cloth.
•  Clean the display with a soft cloth.
•  Check screw tightness on cover display.
•  Store your thermal imager in the optional truck mount or in the delivery case 

provided.

•  All thermal imagers should be maintained using a proper program.
