The Oyster Edge has an IP68 and IK07 rated housing. The device must be sealed carefully to achieve the IP68 rating.

Ensure that the clear silicon seal is in good condition, is lying flat, and is not fouled by any plastic debris or other material.

1. Close the housing, and gently squeeze it shut. Foam on the lid will compress against the batteries, holding them firmly in place.
2. Tighten the 6 screws to a uniform tightness. On the first assembly, the screws may be quite stiff.
   The screws are a thermoplastic screw: 3.5mm x 12mm (BN82428).
   If you are after a stainless steel variant, the product code to source is BN82429.
3. The silicone seal is what is responsible for maintaining the integrity of the housing. So when sealing, we are looking for:
   1. Even pressure along all points of the seal
   2. A uniform gap between the housing lid and base (approx 1mm)
4. If you wish to replace the batteries and open the housing, be sure to check that the silicon seal is in good condition before closing the housing again.

Mounting and Installation

The Oyster Edge can be mounted on the asset to be tracked using screws, bolts, cable ties, magnets, or industrial adhesives. When choosing a mounting point, you have two competing goals:

• To minimise the chances of the device being accidentally crushed, dislodged or discovered by a thief.
• To maximise GNSS scanning and mobile reception and provide adequate ventilation.

Key mounting notes:

• Avoid installing the device in a completely enclosed metal box.
• Avoid installing in a location that will result in elevated temperatures. For instance, mounting the Oyster Edge in direct sunlight on the dash of a non-ventilated cabin may cook the batteries, leading to abnormally short service life.
• If installing in a potentially low signal environment, check the signal strengths reported in device data.
