Key Features:
- Solar-Powered: Utilizes sunlight for continuous operation, minimizing the need for battery changes.
- Loud 129dB Alarm: Features a powerful siren to effectively deter unwanted presence.
- PIR Motion Detection: Detects movement within a range of 5-8 meters and a sensing angle of 125°.
- IP65 Weatherproof: Constructed from high-quality ABS plastic, designed to withstand various weather conditions including rain and dust.
- Easy Installation: No complex wiring required; can be mounted on posts, fences, trees, or walls.
- Low Maintenance: Automatic charging ensures 24/7 protection with minimal user intervention.

Setup and Installation
The Comboss Solar Sound & Light Alarm is designed for straightforward installation and flexible power options.
Charging the Device
Before first use, ensure the device is adequately charged. It supports two charging methods:
- Solar Charging: Install the device outdoors in direct sunlight. The solar panel on top will automatically charge the internal battery. For the initial charge, expose it to direct sunlight for 4-6 hours.
- DC Charging (USB): On cloudy days or if immediate power is needed, use the provided USB cable to charge the device via a DC power source.

Mounting the Alarm
The alarm can be easily mounted in various outdoor locations:
- Location: Choose a location with ample direct sunlight for optimal solar charging.
- Mounting Surfaces: Suitable for posts, fences, trees, or walls.
- Height: Adjust the mounting height between 1 to 8 feet for optimal motion detection and sound dispersion.
- Tools: No special wiring tools are needed. Use appropriate screws or mounting hardware for your chosen surface.
Operating Modes
The Comboss Solar Sound & Light Alarm offers four distinct working modes, selectable via the included remote control, to suit various security needs. The remote control has four buttons: A, B, C, and D, corresponding to the four modes.

Image: Illustrates the four working modes with examples of animals (coyote, deer, fox, rabbit) triggering the alarm in different settings.
- Mode A: 24H Induction (Sound & Flash)
This mode provides continuous protection throughout the day and night. When motion is detected, the alarm will play one of 13 different alarm sounds in a loop and simultaneously activate the strobe light. This mode is ideal for active deterrence against both human intruders and animals at any time. - Mode B: 24H Induction (Flash Only)
In this mode, the device operates 24 hours a day. Upon motion detection, only the strobe light will activate, without any accompanying sound. This is suitable for areas where a silent visual deterrent is preferred, or to avoid disturbing neighbors with loud sounds. - Mode C: Night Induction (Sound & Flash)
This mode is specifically designed for nighttime security. The alarm will only activate when motion is detected during dark hours, playing one of the 13 alarm sounds in a loop and flashing the strobe light. This conserves battery during daylight hours and focuses deterrence when it's most needed. - Mode D: Night Induction (Flash Only)
Similar to Mode C, this mode activates only at night upon motion detection. However, it will only trigger the strobe light, without any sound. This is useful for discreet nighttime visual deterrence in sensitive areas.
Alarm Sounds
The alarm is equipped with 13 distinct sounds to provide varied deterrence:
- Barking Dog
- Gunshot
- Wolf Howl
- Gong Sound
- Eagle Calls
- Firecrackers
- Lion Roar
- Pig Screaming
- Explosion
- Di Sound
- Car Speaker
- Alarm
- Bell/Siren

Motion Detection Range
The PIR motion sensor has a sensing angle of 125° and a detection range of 5-8 meters. Ensure the area you wish to protect falls within this range for effective operation.

Maintenance
The Comboss Solar Sound & Light Alarm is designed for low maintenance due to its solar charging capability and durable construction.
- Cleaning: Periodically wipe the solar panel and sensor lens with a soft, damp cloth to remove dust, dirt, or debris that may obstruct sunlight or motion detection. Do not use abrasive cleaners.
- Battery: The device includes a Lithium Polymer battery (1 AAA equivalent). With solar charging, it is designed for continuous operation. If the device is stored for an extended period, ensure it is fully charged before redeploying.
- Weather Resistance: The IP65 waterproof rating ensures protection against rain and dust. However, avoid submerging the device in water.
Troubleshooting
If you encounter issues with your Comboss Solar Sound & Light Alarm, consider the following common solutions:
- Alarm Not Activating:
- Ensure the device is sufficiently charged. Expose it to direct sunlight for several hours or charge via USB.
- Verify that the motion sensor lens is clean and unobstructed.
- Check the selected operating mode (A, B, C, or D) using the remote control. Ensure it's set to a mode that includes sound and/or flash as desired.
- Confirm that the motion is within the 5-8 meter detection range and 125° sensing angle.
- Alarm Sounds Too Low or No Sound:
- Ensure the device is not in Mode B or Mode D, which are flash-only modes.
- Check for any physical obstructions around the speaker.
- Strobe Light Not Flashing:
- Ensure the device is not in a mode that disables flashing (all modes A, B, C, D include flashing).
- Verify sufficient charge.
- Remote Control Not Working:
- Ensure the remote control's battery is functional.
- Point the remote directly at the alarm unit within a reasonable distance.
