TROUBLESHOOTING STEPS
The BOLT TD50L will not turn on.
The built-in battery pack is very low or has
completely discharged.
Charge the built-in battery pack.
The BOLT TD50L can not connect to a
computer or external power supply.
External power supply has completely
discharged.
Check the external power supply and charge it if necessary.
Computer is turned off.
Power on the computer.
Data cable is damaged.
Replace the USB-C to analog RCA/USB data cable.
The BOLT TD50L can not connect to the
mobile device (smartphone or tablet).
Wi-Fi is not turned on.
Turn on the Wi-Fi in the main menu. See
Wrong Wi-Fi password entered.
On the mobile device, go to
Settings > Wi-Fi
and enter the correct password. The default
password is 12345678. See
Too many Wi-Fi signals near the BOLT TD50L.
Move the BOLT TD50L and mobile device to an area with no or fewer Wi-Fi signals.
Wi‑Fi signal is lost or interrupted.
Smartphone or tablet is out of range of a
strong Wi-Fi signal, or there are obstacles
between the BOLT TD50L and the mobile
device.
• Try again when Wi-Fi signal is stable.
• Relocate the BOLT TD50L closer to the Wi-Fi signal.
The image is too dark / too light.
Display brightness level is too low.
From the home screen, short press the
Brightness button
to adjust the display brightness.
Image is overexposed or underexposed.
Adjust the exposure compensation. See
Main Menu > Exposure Compensation
The GUI is clear, but the image
is fuzzy.
The lens is not focused.
Adjust the focus on the target by rotating the Objective Lens Focus Ring
(14)
There is dust on the interior or exterior optical
surfaces of the lens.
Wipe the outside optical surfaces with the included microfiber lens cloth.
There is condensation on the interior or
exterior optical surfaces of the lens.
• Wipe the outside optical surfaces with the included microfiber lens cloth.
• Allow the BOLT TD50L to dry by leaving it in a warm, dry environment for at least 4 hours.
The aiming reticle shifts after
firing rounds.
The BOLT TD50L is not mounted securely or
the mount is not secured on the BOLT TD50L.
• Check that the BOLT TD50L has been securely mounted.
• Make sure you are using the same brand, type, and weight of the bullets as when the
BOLT-TD50L and weapon were initially zeroed.
• If the BOLT TD50L was zeroed in different environmental conditions, a slight shift of the
zero is possible.
The BOLT TD50L will not focus.
Image settings are not optimal for the
current environmental conditions or the
object being observed.
• Check the outer surfaces of the objective lenses and eyepiece and, where necessary, wipe
away any dust, condensation, frost, etc.
• In cold weather, you can use special anti-fogging coatings, such as those made as for
corrective glasses.
• Adjust the focus on the target by rotating the Objective Lens Focus Ring
(14)
.
• Adjust the image and device settings. See
When the BOLT TD50L is used in low
temperature conditions, the image quality
of the surroundings is worse than in warm
temperature conditions.
Environmental conditions.
In warm temperature conditions, objects being observed (surroundings and background) heat
up differently because of thermal conductivity, thereby generating a high temperature contrast.
Accordingly, image quality produced by the riflescope will be higher. In low temperature
conditions, the background will cool down to roughly the same temperature, and thus the
temperature contrast is substantially reduced and image detail can go down as there is less
contrast in the scene. This is a normal function of a thermal imager and is no indicator of actual
detector performance.
