SET-UP OF FUNCTIONS AND BEAM ALIGNMENT
6
OPERATION CHECK
1) Supply power with cover detached.
2) Set function options.
(Refer to 7. FUNCTIONS DESCRIPTION for
detailed explanation of each option.)
3) Adjust optical angle.
1) Look through view finder on either side of transmitter optical
unit and move until receiver unit is visible.
2) Repeat the procedure for lower optical unit, and then repeat on
receiver.
4) Fine tuning
Initial beam alignment
can be achieved by
using the alignment
tone indicator.
1) Attach the shading
plates (stored on
sides on both TR/RE)
to the lower optics of
both TR and RE.
2) Turn the receiver
alignment tone switch to ON.
3) Adjust the optics with the adjustment screws until
highest tone is reached. (Note: There will be no sound if
the attenuation alignment tone LED is lit.)
4) Reverse the procedure, i.e. attach shading plates to upper optics
of TR/RE and repeat adjustment.
5) After adjustment, replace the shading plates in storage areas
of TR/RE.
6) Turn the alignment tone indicator to OFF.
3) If there is a continuous "beep" sound, detach receiver cover
and re-adjust referring to section 5 part 3) Auto-gain lock
function.
Confirm a Beep sound with the
bottom end of cover lightly pushed
not to interrupt the beam.
Pre-attach cover.
5) Attach cover.
1) Attach transmitter cover, first.
2) Confirm that receiver
sensitivity attenuation LED
stays OFF. Place cover in
position, but do not secure. A
"beep" sound will occur after
5 seconds. After this signal,
secure the receiver cover with
screws.
[Receiver]
1) Sensitivity allowance is automatically set when the beep
sound is initiated.
2) If tone alignment switch is left accidentally ON, tone will
stop when receiver cover is pre-attached.

1) Alarm LED only.
2) Alarm LED and sound check via tone alignment switch. If tone
alignment switch is set to "ON", tone will stop when cover is
replaced but be effective for an audible test of operation for five
minutes after auto-gain is locked.
After installation, alignment and auto-gain set, test operation by walk testing the beam. Two methods may be used :
RE
Lights
TR
1) Check by alarm LED

TR
2) Check by walk test mode
