HMT-1 Safety Guidelines
Battery Performance
A rechargeable battery powers your device. Always use only the original type of RealWear battery that came with the
device. Use the battery only for its intended purpose. Never use any charger or battery that is damaged. If the battery is
completely discharged, it may take a few minutes before the charging indicator appears on the display or before the
device can be used. The full performance of a new battery is achieved only after 3 to 4 complete charge and discharge
cycles. The battery can be charged and discharged for multiple cycles, but it will eventually wear out. Unplug the
charger from the electrical plug and the device when not in use. Ensure that you do not leave the fully charged battery
connected to the charger. If left unused, a fully charged battery will lose its charge over time.
Warning: There is a risk of explosion while charging if a battery other than the specified model is used.
Battery Replacement
If the HMT-1 battery is not charging properly, replace the battery with an original RealWear battery. If a replacement
battery is being used for the first time or if the battery has not been used for a prolonged period, it may be necessary to
connect the charger and then disconnect and reconnect it to begin charging the battery.
Avoid Short Circuit
Do not short-circuit the battery. An accidental short-circuit can occur when a metallic object such as a coin, clip, or pen
causes direct connection of the positive (+) and negative (-) terminals of the battery. This might happen, for example,
when you carry a spare battery in your pocket or toolbox. A short-circuit at the terminals may damage the battery or the
connecting object.
Avoid High Temperatures
Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the
capacity and lifetime of the battery. For the best results, try to keep the battery between -10°C and +50°C (+14°F and
122°F). A device with a hot or cold battery may not work temporarily, even when the battery is fully charged. Battery
performance is particularly limited in temperatures well below freezing.
Battery Disposal
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if damaged. Dispose of batteries
according to local regulations and recycle when possible. Do not dispose as household waste. Do not dismantle, open
or shred cells or batteries. In the event of a battery leak, do not allow the liquid to come in contact with the skin or eyes.
In the event of leak or a hazard seek medical help immediately.
Child Safety
Do not allow children to play with your device or its accessories. Keep it out of their reach. They could hurt themselves
or others or could accidentally damage the device or accessories. Your device and its accessories may contain small
parts, which could be detached and create a choking hazard.
Health and Safety Warnings
Stop using RealWear HMT-1 or its display immediately if you experience a headache, vertigo, dizziness or nausea. Do
not use the HMT-1 display while operating any vehicle. Move the boom arm completely out of your line of sight when
not using the display. Maintain situational awareness of your surroundings while using the HMT-1.
