1. Overview

The InfiRay USA Mini MH25 is one of the smallest fully multi-functional 12-micron

thermal imagers on the market. It can be used as a handheld monocular or helmet

mounted for hands-free use. It’s features include picture-in-picture, Bluetooth,* digital

magnetic compass, pitch and roll measurement, and analog video output. The MH25 is

compatible with rechargeable 16650 and 16340 batteries and can be powered externally

through the USB-C port with a 5V battery pack. The MH25 is operated by an intuitive

menu system and user-friendly rotary encoder button. This one button operation has

positive clicks with each selection and allows for quick and easy operation in dark

environments.

*Requires external remote (Sold Separately)

5. Operation Functions

The Quick Command Menu, Advanced Menu and other functions can be accessed via

the rotary encoder. All menus can be closed by pressing the encoder for 3 seconds.

5.1 Powering On/Off

To power on – hold the encoder button down for 3 seconds.

To power off – point the device down and hold the power button for 3 seconds.

5.2 Digital Magnification

When there is no menu displayed, rotate the encoder to digitally zoom in and out. Digital

magnification will increase when the encoder is rotated clockwise, and digital magnification

will decrease when rotated counterclockwise.

Rotating the encoder slowly will increase or decrease the digital magnification in

increments of 0.1 and rapid rotation will increase or decrease digital magnification by 1.0.

Current magnification is displayed in the upper left icon cluster.

5.3 QCM Quick Command Menu

The quick command menu is activated with a short press of the encoder. The QCM

has four functions including NUC (Non-Uniform Calibration), color palette selection,

brightness adjustment, and laser activation. NOTE: The InfiRay USA MH25 does not have

a laser. Only certain models feature a laser, and the MH25 does not. The laser icon may

be present, but there is no laser. Rotating the encoder will toggle functions and a short

press will activate the function. If the encoder is not activated within 5 seconds the QCM

will disappear automatically. Pressing the encoder for 3 seconds will close the QCM.

NOTE: Pressing the encoder for 3 seconds while orienting the MH25 downward will turn

the MH25 off.

NUC - Short press while the lens is facing down will perform silent NUC. All other

orientations will perform shuttered NUC.

Color Palette - White hot/Black hot/Red Hot/Pseudo color).

Brightness - Screen brightness adjustment.

Laser – None NOTE: The InfiRay USA MH25 does not have a laser. Only certain

models feature a laser, and the MH25 does not. Even though there is a menu for it,

there is no laser.

5.4 Advanced Menu

To activate the advanced menu press and hold the encoder for 3 seconds. Make sure

the lens is not pointing down, as a 3 second press pointing down will power the MH25 off.

The advanced menu displays 5 submenus including Device, Function, Reticle,

Calibration and Setting. Each submenu contains several options and corresponding

options expand (if present) when a submenu is selected, as shown in figure 5-3. Please

note, some menus are disabled. The Reticle and Laser functions are non-functioning on

the MH25 because there is no reticle and no laser.

Menu Operation：

Once the advanced menu is displayed, short press the encoder to toggle through the

5 menu selections. Rotate the encoder to toggle through the selections in each submenu.

Short press the encoder to select a particular setting or function in the submenu and

rotate the encoder to make changes to that setting or function. Short press the encoder to

lock the changes and return to the preceding menu.

Press and hold the encoder for 3 seconds to exit the advanced menu. The advanced

menu will exit automatically after 30 seconds of inactivity. The details of the advanced

menu are shown in table 5-1 and the relevant operation status is shown in figure 5-4, 5-5,

5-6 and 5-7.

6. Preventative Maintenance

6.1 Battery Replacement

▶Power off unit before replacing the batteries;

▶The battery power icon is displayed on the upper right side of the display. There

are four levels of power.

▶When the battery icon turns to red, it means that the power is less than 25% and

the battery needs to be replaced or connect to external power.;

▶To replace the battery, rotate the battery cap counterclockwise, remove old battery

and insert new battery button side down. The correct battery orientation is also noted on

the outside of the battery compartment.

6.2 Product Cleaning and Maintenance

▶Avoid using harsh chemicals or solvents to clean the monocular housing or lenses.

▶Rinse the monocular housing with water and wipe clean with a soft cloth.

▶For the eyepiece and objective lenses, remove any large particles or loose dirt

using compressed air. Fine cleaning should be performed with a lens cloth or lens pen.

Clean water, alcohol, or general-purpose window cleaner may be used to remove stubborn

stains. Avoid using excessive force as this may result in scratching the lenses.

7. General Troubleshooting

Please contact InfiRay USA or an authorized vendor for assistance before attempting

to perform any modifications or repairs beyond the scope of the troubleshooting

procedures in this manual. Unauthorized repairs or modifications may void your warranty.
