Precautions
Only use the charger supplied with the Battery Pack. The use of any
other charger may irreparably damage the Battery Pack or the charger
and may cause fire.
Do not charge the built-in and removable batteries immediately after
moving the device and batteries from a cold place to a warm place. Wait
at least 30 minutes for the device and batteries to warm up.
It is not recommended to charge the batteries with a charger connected
to the USB port of a computer or laptop. It can damage the computer.
Do not leave the Battery Pack unattended while charging.
Never use a modified or damaged charger.
Do not leave the Battery Pack with a charger connected to the power
adapter after charging is complete.
Do not expose batteries to high temperatures or to a naked flame.

Do not drop or strike batteries or charger.
Batteries and charger are not designed to be immersed in water.
Keep the Battery Pack out of the reach of children.

Recommendations for
Battery Use
For long-term storage, the built-in and removable batteries should be
partially charged – from 50 to 80%.
Batteries should be charged at an ambient temperature of 0 °C ... +35
°C. Otherwise, battery life will be significantly reduced.
When using batteries at sub-zero ambient temperatures, the battery
capacity decreases, this is normal and not a defect.
Do not use batteries at temperatures outside the range of -25 °C … +50
°C – it may reduce the battery life.
The battery has a short-circuit protection. Any situation that may cause
short-circuiting, however, should be avoided.

To select a rangefinding reticle, please see the Reticle Typesubsection
in the
To select a unit of measurement (meters or yards) go to the Units of
Measure
Additional Information:
Accuracy of measurement and maximum range depend on the reflection
ratio of the target surface, the angle at which the emitting beam falls on
the target surface and environmental conditions. Reflectivity is also
affected by surface texture, color, size and shape of the target. A shiny
or brightly colored surface is normally more reflective than a dark
surface.
Measuring range to a small sized target is more difficult than to a large
sized target.
Accuracy of measurement can also be affected by light conditions, fog,
haze, rain, snow etc. Ranging performance can degrade in bright

The image of the object being observed is
missing
Possible cause
The object is behind glass, which obstructs thermal vision.
Solution
Remove the glass.
There are several light or black dots (pixels)
on device’s displays or microbolometer

Solution
The presence of such pixels is associated with the manufacturing
technology of displays and microbolometer. It is not a defect.
When using the device at below zero
temperatures the image quality is worse
than at positive temperatures
Possible cause
In warm climates, objects in the background of a thermal image heat up
differently because of thermal conductivity, generating a high
temperature contrast and a sharper thermal image.
In cold climates, objects in the background of a thermal image will cool
down to roughly the same temperature, which leads to a greatly
reduced temperature contrast and a degraded image quality. This is
normal for all thermal imaging devices.
Rangefinder will not measure distance
Possible cause
There is an object in front of the receiver or emitter lens preventing
signal transmission.
Solution
Make sure that: the lenses are not blocked by your hand or fingers; the
lenses are clean.
Possible cause
The device is not being held steadily when measuring.

Solution
Keep the device steady when measuring.
Possible cause
Distance to the object exceeds 1000 m.
Solution
Pick an object at a distance not longer than 1000m.
Possible cause
Low reflection ratio (for example, tree leaves).
Solution
Pick an object with higher reflection ratio (see point Additional
Information in section Laser Rangefinder.
Large measurement error
Possible cause
Inclement weather conditions (rain, mist, snow).
