Overview
Four repelling modes and a blue night light in one plug-in unit.
SDH-046 plugs straight into a wall outlet and starts in Mode 1, with the mosquito icon lit. After a power cut it restarts in Mode 1. It suits indoor spaces such as homes, warehouses, restaurants and offices. Install it 30–50 cm above the floor, away from curtains and furniture; the manual recommends one unit for every 30 m², with several units working together in large spaces.
A short press of the button cycles through the four modes. A 3-second press switches the blue night light (15 lm) on or off without changing the repelling mode. Modes 1 and 2 are ultrasonic and silent to people. Mode 3 adds an audible 200 Hz tone, and Mode 4 adds a flashing LED, so both are meant for rooms where nobody is present.
Modes
One button, four operating modes.
Mode 2 · Mouse icon
Rodent
Constant 25–65 kHz, silent to people. For areas where rodents are active; can run through the night.
Mode 3 · Frequency icon
Variable frequency
Cycles 19–25 kHz, 25–65 kHz and 200 Hz, 4 seconds each. The 200 Hz tone is clearly audible, so use it when nobody is around, for example while you are away.
Mode 4 · LED flash
LED strobe
Runs the Mode 3 frequency cycle together with a continuously flashing LED. For unoccupied rooms at night, since sound and light may cause discomfort to people.

FAQ
Questions buyers ask about SDH-046
Can people or pets hear it?
Modes 1 and 2 are ultrasonic (19–65 kHz) and cannot be heard by people. Mode 3 includes an audible 200 Hz tone and Mode 4 adds a flashing LED, so use both only when nobody is in the room. Pets such as hamsters and birds may react to ultrasound and flashing light; watch them and keep them away from the operating area.
How many units does a space need?
Coverage is 80–120 m² in an open, unobstructed space. Furniture and walls block ultrasound, so the manual recommends one unit for every 30 m² and several units working together in large spaces.
Which plug types and voltages are supported?
Input is AC 90–240 V, 50/60 Hz, with US, EU and UK plug versions confirmed with each order. Power consumption is 5 W or less.
Which certifications does it have?
CE (EMC and LVD), FCC and RoHS 2.0. Our establishment is registered with the U.S. EPA under Est. 97987-CHN-1.
What should users expect at first?
Pest activity may increase at first as hidden pests are driven out of corners; this is normal. Keep the unit running, seal gaps and keep the area clean. For a heavy rodent problem, use traps or baits alongside the repeller.
How is it installed and controlled?
Plug it into an indoor outlet 30–50 cm above the floor, away from curtains, furniture and damp areas. It starts in Mode 1; a short press changes mode and a 3-second press switches the blue night light. After a power cut it restarts in Mode 1.
