4 OPERATION OF THE WHERECALL III
The WhereCall III is a wireless messaging device that is capable of transmitting
simple messages to the WhereNet Infrastructure. These messages can range from
a call for parts for line side material replenishment to a request for supervisor
assistance. There are three modes of operation, Button or Call, Switch, and OFF.
The WhereCall III is shipped in the “OFF” mode.
In button or Call mode the WhereCall III can be used for parts call and other
operations that do not require an indication as to whether the request was
completed. In this mode, the operator presses the button to send the request
message. The display on the WhereCall III will flash the word “CALL” for one
minute and then start to count up in minutes since the call was made. This lets the
operator easily verify how long it has been since they made their request. In the
button mode the WhereCall III will transmit “switch ID 0”.
To turn the WhereCall III on when it is “OFF” (the display will show non
blinking OFF). Press the button once and the tag will resume operation in either
the Call mode or the Switch mode depending on the mode it was in when the off
mode was selected.
In switch mode, the display toggles between “-ON” and “-OFF”. The normal
starting state is “-OFF”. If the operator presses the button, then the WhereCall
will send a message signaling the change in state and the display will change to “-
ON” and transmit “Switch ID 1”. The next button press will cause a new message
to be sent signaling the change of state and the display will change back to
“-OFF” and transmit “Switch ID 0”. In the switch mode the WhereCall III will
send multiple transmissions; at 0, 1, 5, 10, 15, 30, 90, 150 minute intervals and
then every hour after that.
To change modes between Call mode and Switch mode or visa versa; press and hold
the button until the display indicates either “b ?” or “S ?”. (Do not release the
button while the display shows “8888” rather continue to keep the button depressed.)
When either of these is displayed immediately release the button then press and
release it again within five seconds; this will change the operational mode.
