100ft (Concrete construction)
6. Transmission range
Transmission range may decrease under the following conditions:
- Either TD-20U or receiving unit installed on a metal surface.
- Presence of a steel door, reinforced concrete or other metal obstructions between
TD-20U and receiving units.
- Places near strong radio sources such as broadcast stations or substation.
7. Battery replacement
Replace battery every 2 years. Use only 9V alkaline battery.
8. Cleaning
Harsh cleaners such as paint removers or benzene may ruin the surface. Use a soft wet
cloth and mild soap to clean.
1. Harsh environments
Do not use the TD-20U outdoors under severe conditions as out of warranted
temperature, rapid temperature change, high humidity, steam, or smog.
This may cause the unit to malfunction.
2. Impact/Shock
Impact or Shock can cause severe damage or break the TD-20U.
3. Light/Moving object
Direct light or moving objects in front of the TD-20U can cause false alarms.
4. Electric Devices
Use the TD-20U at least 3ft(1m) away from any electronic devices such as TVs,
Radios, PCs, Microwave ovens or any other devices with an electric motors.
This may cause the unit to malfunction.
5. Tampering
Any changes or modifications not expressly approved by OPTEX could void the user’s
authority to operate the equipment.

How To Choose the detection area pattern
1. Use a screwdriver to
open the casing.
2. Choose from the two
detection area
patterns by pointing
the arrow to either
.
“F: fan pattern”
or
“L: long range.”
3. Turn the mask to
the optimal position
for the detection
area pattern you
have chosen.
This
mask is adjustable
clockwise
/counterclockwise
(±90°), horizontally
(±5°) and vertically
(±45°).
NOTE:
If there is an area within the fan-pattern detection area
that you do not want to include, mask part of the lens with a tape.
4 DETECTION AREA PATTERN
Fan Pattern(Default setting)
Selecting the appropriate detection area pattern for the TD-20U enhances its detection ability and immunity against false alarms. The TD-20U is shipped to you in the fan pattern setting,
but you can easily select either fan or long range. Select the long range detection area for Drive-Up announcer applications.
