Using Voice Control (Optional Feature)
The Norlase Leaf photocoagulator is capable of receiving voice commands for certain parameter
changes to aid the physician in changing parameters without engaging the touchscreen user
interface.
The voice control feature works by listening for a “wake up” command, “OK Norlase”, which
activates the tablet to listen for the proper parameter change command. When a command has
been successfully recognized, the system will audibly call back the requested command and any
parameter setting that has been changed. If a command is not recognized, a two note audible
response will indicate no command was recognized.
Please Note: The wake-up word and voice commands must be stated EXACTLY as listed
below, clearly, in English and within the microphone range of the user interface tablet to
ensure high success of a recognized command. Any deviation from the exact command
will not be recognized. It is helpful to memorize this list of commands in order to ensure
consistent success of the voice commands.
Wake-Up Phrase: OK Norlase
The wake-up phrase will activate the system to listen for a recognized command.
Immediately after hearing “OK Norlase” the system will respond with a two-step
audible tone (♬) that indicates it is listening for the next command. The next
command must be issued within 5 seconds or the system will return to listening for
the wake-up word to be said again.
Please wait one second after the audible tone completes before issuing the desired
command.
Examples of correct sequencing for Voice Control:
User System 1 second User System Response
“OK Norlase” “ ♬” 1 second “Enter Treat” “Treat Mode Selected”
“OK Norlase” “ ♬” 1 second “Power Higher” “Power at XXX”
“OK Norlase” “ ♬” 1 second “Duration Lower” “Duration at XXX”
“OK Norlase” “ ♬” 1 second “Pulse Count” “Pulse Count at XXX”
