Display Brightness Level
The messenger offers an option to choose between three brightness levels for display. The lowest
brightness level is perfect for underground use while it may be difficult to see/operate outside or
in a building. One word of warning, the higher the brightness setting, the more current the
messenger will draw. There is roughly a 30mA difference in current draw between the highest
and lowest brightness setting.
To adjust the brightness levels select the brightness setting in the list of options. To change
between the brightness levels, use the up/down arrow buttons and then press the middle bottom
button to make the change. This setting is saved to memory and it will be restored the next time
the messenger is reset.
Auto Acknowledgment Messages
The messenger has the ability to send a preset message out either when a message is received, if
a message is read, or send a message when a message is received and read. The option of using
this function will be left up the Mine personnel using the messenger. This option is different
from a acknowledgement packet between two radio devices. Having the option of send auto
acknowledgment messages users will be able to receive and read messages telling them that the
message they sent has been received or read by the person to which it was sent.
When the “Auto send a read acknowledgement message” option is selected the messenger will
automatically send a message to the source address with a message “Message Read” when
reading a new message.
When the “Auto send a received acknowledgement message” option is selected, the messenger
will automatically send a message to the source address with a message “Message Received”.
When “Auto send a read and received acknowledgment message” option is selected, the
messenger will automatically send a message to the source address with a message of “Message
Read” when reading a new message and a message to the source address with a message
“Message Received” when receiving a new message.
When “No auto acknowledgment messages” option is selected then there won’t be any
acknowledgement messages automatically sent from the messenger.
To change the auto acknowledge message, go to the list of options and move the arrow down to
the line that says “Message Acknowledge” and press the bottom middle button. The first thing
the menu shows is the current setting, then below the line it will show the setting that is currently
selected. To change a the setting, use the up/down buttons to cycle between the four options and
then press the bottom middle button, “select”, to change the setting.
