Offset on-grade clamp position

- clamp position is sensed automatically
and displayed. Offset clamp position
moves the on-grade location to allow
more grade information to be displayed
above grade. This is useful in applica­tions where going below grade is not
required, i.e. driving stakes down to
grade.

EMC Declaration of Conformity

This device has been tested and found to comply within the limits for
a Class B digital device for radio noise for digital apparatus set out
in the Radio Interference Regulations of the Canadian Department
of Communication, and is pursuant to part 15 of the Federal
Communication Commission (FCC) rules. These limits are designed
to provide reasonable protection against harmful interference in a
residential installation.
This receiver generates radio frequency. If it’s not used in accordance
with the instructions, it may cause harmful interference to radio or
television reception. Such interference can be determined by turning
the receiver off and on. You are encouraged to try eliminating the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the laser and the receiver.
For more information, consult your dealer or an experienced
radio/television technician.

CAUTION: Changes or modications to the receiver that are not

expressly approved by Trimble could void authority to use the equipment.

1. Pair the Two HL760’s
Turn on both HL760 Laserometers that are to be paired and follow below directions for both units.
Enter the MENU of the HL760’s. The RDIO functions will be shown
Enter the RDIO functions to display the MODE selection
If HL is not displayed, Enter the MODE function and scroll up or down to select HL for each HL760 and ENTER.
Scroll down to PAIR function. ENTER to activate pairing.

The PAIR symbol will rotate briefly until both units complete the PAIR operation.
PAIR OK indicates function complete.

2. Remote Operation

Turn both HL760’s Off.
The first HL760 turned on becomes the laser SENSOR (receiver). The second HL760 turned on becomes the
REMOTE DISPLAY / CONTROL PANEL.
Turn on the HL760 that is desired to be the SENSOR first. Mount at the desired elevation so that it can receive the
laser beam.
Turn on the HL760 that is desired to be the REMOTE DISPLAY / CONTROL PANEL second.
RMT.D – OK will be displayed.
Press ENTER to operate this HL760 as the REMOTE DISPLAY / CONTROL PANEL.

NOTE: If ENTER is not pressed, both HL760’s will revert to standard operation.

During REMOTE DISPLAY / CONTROL PANEL operation, RMT.D is displayed. The Unit will remotely
display the elevation readings of the SENSOR, as long as the Antenna symbol shows the two are within
radio range of each other up to 220 meters (720 ft).

The RMT.D unit can remotely adjust the Accuracy and Units of Measure of the SENSOR.

A) HL760 is

in the laser beam

and the

power is on:

Press any switch to return to normal
operation.

The current elevation read­ing will be held. A flashing
display will confirm the
reading has been captured

.

1 x quick

B) HL760 is

out of the laser beam

and

power is on:

A short intermittent
beep (The beeper
will turn on to Low if
turned off.)

+

1.

Press any switch to return to normal
operation.

2. Place the HL760 in the beam.

(Example: Fasten it to a measuring
rod, bring the

HL760

into the laser

beam. You now have 5 seconds to
plumb the rod and get the reading
captured.)

The beeper will
chirp rapidly after
approximately 5

seconds to confirm
beam capture. A flashing
display will also indicate
the reading has been
captured

Initialization:

1. Test of LCD, LED and beeper

2. CAL: Calibration (3 sec.)

3. Unit is ready for use.

(Do not power up the unit in a laser beam
or strobe. If detected, the unit will display
“E200” and revert to the previous
calibration.)

The selected unit of measure determines
the displayed deadband (accuracy).

The current accuracy is stored in memory
and will be retained when the unit is turned
off or when batteries are replaced.

The current beeper

memory and will be
retained when the unit is
turned off or when bat­teries are replaced.

The current unit of measure is stored in
