Overview
More output for bigger rooms, with a strobe that only works at night.
SDH-041 runs from a wall adapter (AC 100–240 V in, DC 9 V out) and sits on the floor, where most rodents travel. A switch on the back picks the mode: TEST makes an audible sound to confirm it works; ULTRA runs a 22–35 kHz variable-frequency sweep; TRANS holds a steady 25 kHz; DUO runs both speakers at once. Blue and green indicators show which speaker is active.
Press the LED button to add the nine-LED strobe. A light sensor keeps it off during the day and lets it flash at night, cycling through three flash speeds for 30 seconds each. Keep at least 1 m clear around the unit: ultrasound does not pass through walls, furniture or cabinets.
Four modes
Pick one speaker, the other, or both.
ULTRA · Blue
Variable frequency
22–35 kHz ultrasonic sweep that keeps changing so rodents do not get used to it.
TRANS · Green
Fixed 25 kHz
A steady, high-intensity 25 kHz ultrasonic tone from the second speaker.
DUO · Blue + Green
Both speakers
Both ultrasonic outputs at the same time for the strongest coverage.

FAQ
Questions buyers ask about SDH-041
Where does it work best?
Garages, warehouses, basements, storerooms and large living spaces. Place it on the floor, since most rodents travel along the ground, with at least 1 m clear around it.
Can people hear it?
ULTRA, TRANS and DUO are ultrasonic and inaudible to most adults. TEST is deliberately audible and is only for checking that the unit works.
Will the strobe flash during the day?
No. After you turn it on with the LED button, a light sensor keeps it off in daylight and lets it flash at night. Press the button again to turn the strobe off.
How long until it works?
It starts within a few days; the best effect usually comes after 2–4 weeks of continuous use. Rodents can seem more active at first as they are disturbed. Keep it running all year rather than on and off.
Is it safe for pets?
It uses no chemicals or traps. Do not use it near pet rodents such as hamsters and guinea pigs, rabbits or pet spiders.
Which certifications does it have?
CE (EMC), FCC SDoC and RoHS. Our establishment is registered with the U.S. EPA under Est. 97987-CHN-1.
