FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE
STATEMENT
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
This transmitter must not be co-located or operated in conjunction with any other antenna
or transmitter.
The available scientific evidence does not show that any health problems are associated
with using low power wireless devices. There is no proof, however, that these low power
wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio
frequency energy (RF) in the microwave range while being used. Whereas high levels of
RF can produce health effects (by heating tissue), exposure of low-level RF that does not
produce heating effects causes no known adverse health effects. Many studies of low-
level RF exposures have not found any biological effects. Some studies have suggested
that some biological effects might occur, but such findings have not been confirmed by
additional research. WX-CH450 has been tested and found to comply with FCC/IC
radiation exposure limits set forth for an uncontrolled environment and meets the FCC
radio frequency (RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of the
IC radio frequency (RF) Exposure rules.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
This device complies with Part 15 of FCC Rules and Industry Canada license-exempt RSS
standard(s). Operation is subject to the following two conditions: (1) this device may not
cause interference, and (2) this device must accept any interference, including interference
that may cause undesired operation of this device.

Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry
Canada. To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more
than that necessary for successful communication.

System Overview
A repeater is used when you need to extend the range of an All-In-One Headset and Belt
Pack to include areas where reception was previously not available.
One repeater can be registered to one lane of a Center Module (CM).
In the case of a Single Lane CM (WX-CC411), one repeater can be registered to the
CM.
In the case of a Dual Lane CM (WX-CC412), two repeaters can be registered to the CM,
one for Lane A, the other for Lane B.

2 Procedure Overview
2 Procedure Overview
When registering and installing the repeater, follow the procedure below to ensure
smooth operation.
Registering the Repeater
IMPORTANT
Register the repeater to 1 CM only. You cannot register to multiple CMs.
1. Plug in the repeater’s AC adaptor into an outlet near the CM.
• After plugging in, the STATUS LED will turn green.

*1
The cable is already connected when purchased.
2. Set up the CM for registration.
• Refer to the documentation for the CM.
3. Within 2 minutes of setting up the CM for registration, press and hold down the
repeater’s PROGRAM button for approximately 3 seconds.

2 Procedure Overview
Note
The LED may turn amber or red, or flash red, depending on the strength of the
signal.
4. Unplug the repeater’s AC adaptor and move the repeater to the installation location.
• Unplugging the AC adaptor will not cancel the registration.
Deregistering the Repeater
1. Deregister from the CM side.
• Refer to the documentation for the CM.
• You do not need to deregister from the repeater side.
Notice
• Even after deregistration, the information of the CM that the repeater was
registered to remains on the repeater.
To prevent misuse, unplug the AC adaptor of the repeater.
• To return the repeater to its factory default state, refer to "4 Returning the
Repeater to Factory Default (Page 19)".
Installing the Repeater
Follow the procedure below to install a repeater in a suitable location. The repeater must
be registered to a CM beforehand (refer to "Registering the Repeater (Page 13)").
Note
An AC outlet is required at the installation location.
Coverage Area
As a guideline, the recommended distance for the following connections is 100 m (without
obstacles).
• CM and repeater
• Repeater and All-In-One Headset
Install the repeater where the signal is steady (the RSSI/ID LED should be green or
amber) as far as possible from the CM. If the repeater is installed too near the CM, the
All-In-One Headset will receive the signal directly from the CM. In this case, the repeater
will be ineffective.

 15
2 Procedure Overview
1. Temporarily install the repeater within the CM coverage area.
2. Move the All-In-One Headset or Belt Pack to the area where they will be used and
check that communication is smooth and there are no disconnections.
• If communication is not smooth, re-install the repeater in a different
location.
3. If the temporary installation location is suitable, install the repeater completely.
• For details about wall mounting, refer to "3 Wall Mounting (Page 17)".
Installation Examples
• If walls or obstacles exist between communicating devices, the signal may become
weak or disconnected.
• If 2 repeaters are registered to the same CM, do not place them near each other.
Doing so may cause signal interference or noise.

Mounting
WARNING
• Make sure that the wall that the unit will be attached to is strong enough to
support the unit (approx. 88 g [3.1 oz]). If not, it is necessary for the wall to be
reinforced.
• Only use the wall-mounting equipment (screws, washers) included with the unit.
• When this unit is no longer in use, make sure to detach it from the wall.
CAUTION
• When driving the screws into the wall, be careful to avoid touching any metal
laths, wire laths or metal plates in the wall.
• Do not stretch or bend the cable. Also, do not allow anything to rest on the cable.
• The unit and the cable should never be placed near or over a radiator or other heat
source.
• Do not bundle the cable that is connected to the unit with the AC power cords of
machines located nearby.
• Make sure the cable is securely fastened to the wall.
1. Place the reference for wall mounting on the wall to mark the 2 screw positions.
2. Install the 2 screws and washers (included) into the wall.
Note
• Make sure that the screw heads are at the same distance from the wall.
• Install the screws perpendicular to the wall.

4 Returning the Repeater to Factory Default
After using the repeater, you can return it to its factory default state by pressing the button
on the back of the repeater.
1. While pressing the PROGRAM button, plug in the repeater’s AC adaptor, and hold the
PROGRAM button for more than 10 seconds.
• The STATUS LED turns amber, and then flashes amber.

5 Troubleshooting
PROBLEM/QUESTION PROBABLE CAUSE/ANSWER PAGE
• The RSSI/ID LED does not
turn on.
• The repeater is not registered.
→ Register the repeater. 13
• The RSSI/ID LED flashes
red.
• The CM is not turned on.
→ Turn on the CM. –
• The signal is too weak and the repeater is out
of range.
→ Install the repeater where the signal is
steady and the RSSI/ID LED is green or
amber.
14
• Can I register to more than
1 CM at the same time?
• You cannot register 1 repeater to more than
1 CM. –
• Can I install the repeater
where the RSSI/ID LED is
not green?
• You can install the repeater where the
RSSI/ ID LED is red, but communication
may be unstable.
It is recommended to install the repeater
where the signal is steady and the RSSI/ID
LED is green or amber.
14
• Can I install the repeater
outside?
• Do not install the repeater outside.
–
• Communication quality does
not improve after installing
the repeater.
• Is the RSSI/ID LED red or flashing red?
→ Re-install the repeater in an area where
the RSSI/ID LED is green or amber. 14
• Is the repeater installed near the CM?
→ Installing the repeater near to the CM may
cause the All-In-One Headset or Belt
Pack to receive the signal directly from
the CM, making the repeater ineffective.
Re-install the repeater nearer to where
the All-In-One Headset or Belt Pack is
used.
