2. Mounting the Strobe Siren
The siren can be fixed to a wall using screws or placed on a flat surface.
- Wall Mounting:
- Choose a prominent location for the siren, ensuring it is within the wireless range of the panic buttons (up to 100m/328ft in open areas).
- Use the siren's base as a template to mark drilling points on the wall.
- Drill holes, insert wall plugs, and secure the siren's base to the wall using the provided screws.

- Adhesive Mounting:
- Clean the desired surface thoroughly.
- Peel off the protective backing from the adhesive sticker and firmly press the panic button onto the surface.
- Screw Mounting: If a more permanent fixture is desired, use small screws (not explicitly mentioned as included for buttons, but implied by "screws for siren" and general installation practices) to secure the button to a wall.
- Placement: Place panic buttons in strategic locations such as bedrooms, living rooms, near entryways, or in areas where emergencies might occur.

- To exit pairing mode, briefly press the Volume Button/Registration Button again, or wait 10 seconds for it to automatically exit.

Maintenance
1. Battery Replacement
Refer to the "Powering the Strobe Siren" section under Setup for detailed instructions on replacing the AAA batteries in the siren unit.

Consult the button's specific instructions or contact support for battery type and replacement procedure.
2. Cleaning
Wipe the siren and panic buttons with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components. Ensure no liquid enters the devices.
