R9 • System Receiver
10
The R9 senses the plane of laser light
and indicates a height position relative to
the plane (high, low, or on grade). The
R9 displays height information on a five
channel front LCD and a three channel
rear LED display. In addition to the visual
displays, an audio tone indicates high,
low, or on grade. When the R9 is
centered at the beam height, an on grade
"bar" indication is displayed. If the R9 is
high or low, "arrows" show the proper
direction to move the R9, in order to get
an on grade indication.
The R9 has three control switches, power
on/off, tone high/low/off and on-grade
accuracy select. Press the power switch
to activate the R9. The audio sounds and
the LCD displays the tone and accuracy
icons. The R9 is ready to operate in
standard accuracy and loud tone. Pressing the volume switch once changes
to low tone, twice turns the tone off. When the tone is off, there will still be a
single tone the first time the R9 senses a laser signal. Pressing the accuracy
switch once changes to the coarse setting, twice changes to fine. The R9
automatically turns off if no laser strikes are received for twelve minutes.
The R9 is powered by a 9 volt battery that lasts approximately 60 hours.
When the battery is nearly used up, the low battery indicator will be displayed
on the LCD. To replace the battery, locate the battery door on the back of the
housing and slide the door toward the bottom of the receiver. Remove the
battery from the compartment (you may need to tap the R9 on your palm to
free the battery). Replace the battery following the diagram molded on the
battery door.
