Overview
Two speakers, three modes and a blue night light in one plug-in unit.
SDH-045 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. Two ultrasonic speakers send sound in two directions to reach more of the room. 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 three 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, so use it when nobody is in the room.
Modes
One button, three 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 while you are away.
Night light
Blue LED
15 lm blue night light, switched on or off with a 3-second press. Light and repelling mode work independently.

FAQ
Questions buyers ask about SDH-045
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, so use it only when nobody is in the room. Pets such as hamsters and birds may react to ultrasound; watch them and keep them away from the operating area.
How is it different from SDH-046?
Both share the same frequencies, blue night light and 80–120 m² coverage. SDH-045 has a dual-speaker housing and three modes; SDH-046 adds a fourth mode with an LED strobe for empty rooms.
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.
What should users expect at first?
Pest activity may increase at first as hidden pests are driven out of corners; this is normal. Keep it running continuously; activity usually drops noticeably after 2–4 weeks. Seal gaps and keep the area clean.
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) and RoHS 2.0. Our establishment is registered with the U.S. EPA under Est. 97987-CHN-1.
