Activate batteries
Remove the strip to activate batteries.
Once inserted, the LED next to the GPS antenna should flash briefly. If it does not, it means that the unit has not yet been reset. In that case, remove the batteries for a minute or two to drain off any residual charge, then reinsert them.

Close housing
- Place the lid on the gateway and squeeze it gently untill it is closed. The foam in the lid will press against the batteries and hold them firmly in place when the unit is flipped over.
- Tighten the 8 screws evenly. On initial assembly, the screws may be quite stiff.
Be sure to place the cover correctly. The foam should lie over the batteries. Should you fasten the cover the wrong way round, you will damage the gateway

Installation
The gateway can be mounted with screws, bolts, cable ties or industrial adhesives to the object to be tracked.
Be careful when choosing a mounting point!
- Reduce the chance of accidental crushing or detachment.
- Increase GPS and cellular reception by mounting the gateway in a good location. Provide adequate ventilation.
When the gateway is used as a battery-powered device reception is critical to its performance.
Do not place the gateway under a steel cover plate to avoid reception problems.

After installation
1. After installing the gateway and the sensor in the tank, fill the tank completely.
2. If in your project have not yet created assets of the tank, do so first. You can also change the name of an existing asset, should this be necessary.
To visualize the newly installed tank, add it to an asset group.
Adjust the metadata "Tank100pct" and enter here the 4-20mA value when the tank was fully refueled.
Please note! The tank monitor sends its data every hour, wait until you are sure that this is the highest value.
When you have customized your metadata you can use the path "tank_level," this path is percentage based
add assets, asset groups, customize asset metadata, change asset name

Replacing batteries
Wanneer een 4-20mA sensor is aangesloten aan de gateway dienen er Lithium Thionyl Chloride (LTC) batterijen gebruikt te worden.
Niet alle LTC-batterijen zijn hetzelfde gebouwd – kies in het algemeen voor batterijen van het Spiral Type. Accu’s van het Bobbin Type kunnen mogelijk niet genoeg piekstroom leveren.
If you want to replace the batteries and open the housing, make sure the silicone seal is in good condition before closing the housing again.
