Safety Guidelines
Battery Performance
A rechargeable battery powers your device. The device comes with an inbuilt
battery which is not replaceable. Never use any uncertied charger. 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.
There is a risk of explosion while charging if an incorrect battery other than the
specied model is used.
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 -20°C and +60°C (-4°F and
140°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 the device in re as it contains an inbuilt battery which
may explode. Dispose of the device 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-1Z1 or its display immediately if you experience
a headache, vertigo, dizziness or nausea. Do not use the HMT-1Z1 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-1Z1.

Using Voice Commands
WearHF™ is an innovative software solution that enables you to use the
RealWear HMT-1Z1 as a hands-free device. It is easy to use and loaded with
intuitive functions.
Speech Recognition — Say What You See
HMT-1Z1 operates based on speech recognition. Instead of pressing or
tapping a control button on the screen, all you need to do is speak the
name of the respective control. All the commands associated with the
specic screen are displayed clearly on the screen. HMT-1Z1 uses the
latest technology for advanced noise cancellation and speech recognition
and works even in the harshest noisy environments. It can recognize many
different languages and accents and can detect the command even if you
speak in a low voice. You can activate the device by speaking the name of
any control. For example, the Home Screen has 3 large icons with respective
feature names. To access these applications, you can say the application
name and the corresponding screen is launched.
Global Commands
HMT-1Z1 can also recognize certain voice commands that can be activated
from any screen. These are known as global commands. The following
is a list of global commands in English. For global commands in other
languages, refer to the respective user guide.
Voice Command Action
“Navigate Home” Navigates to Home Screen
“Navigate Back” Navigates to previous screen
“My Controls” Navigates to system control panel
“Mute Microphone” Mutes the microphone temporarily
“My Notications” Opens Notication section
“Recent Applications” Opens Applications running in background
“Show Help” Displays pop-up window with the help for commands
associated with the current screen
Echo Cancellation
HMT-1Z1 comes with echo cancellation feature to reduce any audio
feedback that may be picked by the microphone while the speaker is used.
Auto Mute/Auto-Unmute
When the HMT-1Z1 is left idle without any physical movement, either on a desk or on a hardhat, auto-
mute feature will get activated after 30 seconds, the speech recognition is disabled automatically. A
red warning symbol is displayed on the screen. Once the HMT-1Z1 movement is detected, the speech
recognition will resume automatically, and the warning symbol will disappear.
You can enable or disable auto mute from “My Controls”.
Anytime Access Help
You can access the help information regarding the commands associated
with a particular screen, with “Show Help” command. The “Show Help”
command is displayed on all the screens. The help screen is displayed as a
pop-up window. This pop-up window is displayed for 2 Seconds.

17

Alternate Speech Recognition
Sometimes, the control on the screen has no name, scroll button without a
label, or a le button with lename such as 3454-x.pdf, set as the label.
In such scenarios, WearHF™ automatically proposes an alternative speech
command, and assigns a number. This number is displayed next to the
respective control on the screen. To recall the specic control numbers for
that screen, say “Show Help”.
To select a specic control, you need to use the number assigned to it. For
example, you can say “Select item 1” to select the rst unpronounceable
button, or “Select item 2”, to select the second unpronounceable button.
Mute Microphone
To stop the speech recognizer, say “Mute Microphone”. The device will not
respond to your voice commands while the microphone is muted, and a red
warning sign is displayed on the screen.
To restart the speech recognizer, tap the Action button on the side of the
device, located next to the Power button.
Scroll Up and Down
You can scroll and view different portions displayed on the screen, using the
following voice commands.
Voice Command Action
“Page Up” Navigates to 1 page up
“Page Down” Navigates to 1 page down
“Page Left” Navigates to 1 page left
“Page Right” Navigates to 1 page right
“Show Help” Displays pop-up window with the help for commands associated
with the current screen
Head Gesture
The following features do not support page up/down and left/right —
• My programs
• My les
• Document viewer

18
© 2018 RealWear, Inc. All rights reserved.
For example, In Settings page, we can use voice command “Page down” to
scroll down and “Page Up” to scroll up.
At any point of time if you want to use head gestures instead of voice
commands, say “scroll enable” and we can use head gestures to scroll up
and down.
