Features and Functions (cont.)
07. Audio Port—is the opening the
sound comes out of.
08. Battery Housing—holds two
AA alkaline or Ni-Cd batteries.
The battery-housing door is
also used to attach the receiver
to a custom grade rod or
magnetic mount without the
general-purpose clamp.
09. Remote Contacts (HR500 only)—
provide grade-display signals to a
radio remote control.
10. LEDs—show the position of the receiver relative to the laser beam (above grade,
on grade, or below grade).
11. Front and Back Photocells

(HR500 only)—detect the laser
beam when it strikes the receiver.
The dual photocells allow you to
face the LCD and LEDs and have
access to the control buttons,
regardless of your position relative
to the laser beam. If the receiver
does not detect the laser beam for
30 minutes, the receiver shuts
off automatically. The HR400
has front photocells only.
12. Remote Mounting Channels—
provide a recess for the radio remote
control mounting guides to fit into
so the radio remote control can be
attached to the receiver.
