The HMT-1 and HMT-1Z1 are built rugged, but to ensure a long and healthy life:
- Power off the device or put to sleep when not in use.
- Store the HMT device in a cool, dry place.
- Place the device on a level surface or securely hang it on a wall.
- If mounted, you can keep the HMT device connected to a hard-hat or bump cap as needed.
