⑤Replace the cover and tighten the fixing screw.
Once the cover is fixed, the unit automatically
starts adjusting the transmission power
with short pip sound.
Be careful not to block the optical unit
(protection line) with your body or hands
until pip sound stops.
(It may take max. 10 sec.)
If pip sound stops, the optical axis adjustment is completed.
In case pip sound continues, go back to [
2. Distance check
]
and do the setting again.
①Ensure that the monitor output changeover switch is set to
"Distance". When adjusting the optical axis by changing the
installation distance, long press the distance setting button
(short pip for 5 seconds or more)
before proceeding
to the next step.
Especially at short distance, the high-power beam output from
the transmitter may reflect on objects
(walls, signboards, utility poles, etc.)
near to the protection line.
Therefore, adjust correctly
when installing.
②Insert a test meter into the monitor jack and check the voltage.
Monitor output level corresponds to the distance.

③If the distance to the reflector and the converted value of the
test meter do not match, fine adjust the optical axis of the lens unit
or remove any objects near to the protection line.
④Press the distance setting button.
The distance between the sensor and the
reflector is set while pip is sounding.
Be careful not to block the optical unit
(protection line) with your body or hands.
①For the light reception level check, set the monitor output
changeover switch to " Reception ".
②Set tone indicator setting to “ON”.
If the tone indicator is undesirable (at night), proceed directly to ④.
③Fine-tune the optical unit the tone becomes continuous and as
high-pitched as possible.
④ For more accurate adjustment, insert a test meter into the monitor jack
and check the voltage.
As a guide, the monitor voltage is shown in the above table.
However, adjust the sensitivity to as high level as possible in order
to improve environmental resistance.
The monitor voltage of the light reception level may change due
to the ambient temperature or just after turning on the power.

By this operation, the distance between the sensor and the reflector is
memorized so that the adjustment and alarm judgment are
properly performed. So be sure to press the distance setting button.
Before pushing this button, the pitch of tone indicator and
monitor output voltage are kept based on the previous setting.
So be sure to make adjustment after pressing the button.
※Once memorized, the setting will not be reset without pressing the
button again, even if the power is turned on again. When incorrect
distance is set, go back to [

again.

In case tone indicator is “ON”, walk test mode follows for 5
minutes and makes pip sound when detecting.
→
Refer to “
9. OPERATION CHECK
”
※Once walk test mode is completed, no pip sound is heard even with
the tone indicator "ON".
(Note)
If no sound comes out, the sensor unit may not face the direction of the
reflector. In this case, go back to [
1. Before checking
] and do the setting
again. Also check that the tone indicator switch is ON.
When the direction of the optical axis roughly matches the reflector,
a beep sound begins which changes according to the light reception
level as below.
