Mode switch

No power.

1×, 2×, 3×, 4×, 8×

A and B together: calibrate

Positions run clockwise from 1 to 4. Turn counterclockwise to go back toward 1.

Turn the switch clockwise from 1 to 2, 3 or 4 to power on.
Wait about 10 seconds. The buttons do not respond until then.
Turn the switch counterclockwise to 1 to power off.
Settings reset to defaults at every power-up: White Hot, brightness 50, contrast 50, 1× zoom.

The buttons latch. Press once to latch it, press again to release it. Each press or release is one click.
Position 4: a latched button keeps adjusting until you release it.
Both together: position 4 calibrates. In positions 2 and 3, repeated presses start advanced functions, including a permanent dead-pixel correction (see the manual), so avoid them. Release both before the next input.

Automatic: shortly after power-on, then about every 5 minutes. The image freezes briefly. This is normal.
Manual: switch to 4, press A and B together, then release both. Use it when the image looks uneven or ghosted.

One unprotected 18350 lithium-ion cell. It has no built-in protection, so never short its terminals.
Charge it outside the unit in a single-cell lithium-ion charger (4.2 V). Never charge it inside the unit.
Do not use a dented, swollen, leaking, hot or torn-wrap cell.

Warning

Never aim the lens at the sun or other intense heat. It can damage the sensor.

Problem	What to do
No image	Check the cell is charged and installed the right way round. The switch must be in 2, 3 or 4. Wait about 10 seconds.
A button seems dead	Release both buttons. If it was just after power-up, wait about 10 seconds.
Brightness will not change	The button was latched before you turned to 4. Release it, then latch it again.
Image uneven or ghosted	Run a manual calibration: position 4, press A and B together.
Image freezes for a moment	This is calibration. It is normal.

Clean the lens only with a soft, lint-free cloth.
