Troubleshooting

Some problems that may arise when using the Konftel 60W are described below.

Connection and pairing

1. The Konftel 60W does not appear in the display when you try to add a new
device to the phone. Make sure you have followed the instructions on page 3.
Check or redo the settings in the phone.

2. A special Bluetooth function (pages 6-7) that is supported by your phone does
not work with the Konftel 60W. Re-add your phone using another ”pairing mode”

ENGLISH

by pressing the Tuning button for 4 seconds instead of 2 seconds until you hear
2 beeps. The Konftel 60W will then appear as a handsfree profile device instead
of a headset profile device.

Connection with switchbox to a system telephone

1. Is the Konftel 60W properly connected? See the page on connecting a
telephone.

2. Are the LEDs red? If so the Mute button is activated. Press the button to
deactivate.

3. Have you added extension cables to the system? Remove the cables and then
reconnect them to see if the system is working.

4. Check the Selector switch position on the bottom of the switchbox. The Selector
switch position can be set to I or II depending on which system telephone your
Konftel 60W is connected to.

Connection to computer

If calls are audible through the computer headset but not through the Konftel 60W,
check that the software and sound card are configured to handle full duplex.

Troubleshooting and maintenance

Poor sound quality, echo

1. Make sure that the Konftel 60W is within your phone’s working range.

2. Check the position. The unit is designed to stand flat on the table. Avoid
moving it around during the call. Do not place the unit too close to a wall or
under objects, such as lamp shades or plants.

3. Tune the Konftel 60W manually. See the page on manual tuning.

4. Has the Volume control been set correctly? See the page on Microphone
volume control.

5. Does the receiving party have a conference unit, sound card or software which
are not designed to handle full duplex?

6. When the unit is connected to a PC, radio frequency interference may cause a
discernible sound. The sound will disappear when the interference stops.

Possible applications

Headset

Instead of a handset, you can connect a headset to the switchbox. You may now
switch between a call via the headset or the Konftel 60W via the On/Off button.

Note that the headset must be adapted to suit your telephone system.

Other applications

The Konftel 60W is a very versatile conference phone. For further information
about how to use your unit, please refer to the Konftel website www.konftel.com/
Products (see Konftel 60W/applications).

FCC Statement

FCC Statement

This equipment complies with Part 68 of the FCC rules and the requirements
adopted by the ACTA. On the bottom of this equipment is a label that
contains, among other information, a product identifier in the format
US:5RWTXNANC1049. If requested, this number must be provided to the
telephone company.

An applicable certification jack Universal Service Order Code (USOC) for the
equipment is provided (i.e., RJ11C ) in the packaging with each piece of
approved terminal equipment.

A plug and jack used to connect this equipment to the premises wiring and
telephone network must comply with the applicable FCC Part 68 rules and
requirements adopted by the ACTA. A compliant telephone cord and modular
plug is provided with this product. It is designed to be connected to a compa­tible modular jack that is also compliant. See installation instructions for
details.

The REN is used to determine the number of devices that may be connected
to a telephone line. Excessive RENs on a telephone line may result in the
devices not ringing in response to an incoming call. In most but not all areas,
the sum of RENs should not exceed five (5.0). To be certain of the number of
devices that may be connected to a line, as determined by the total RENs,
contact the local telephone company. [For products approved after July 23,
2001, the REN for this product is part of the product identifier that has the
format US:5RWTXNANC1049. The digits represented by 05 are the REN
without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the
REN is separately shown on the label.]

ENGLISH

NOTICE: If your home has specially wired alarm equipment connected to the
telephone line, ensure the installation of this Konftel 50 does not disable your
alarm equipment. If you have questions about what will disable alarm equipment,
consult your telephone company or a qualified installer.

NOTICE: According to telephone company reports, AC electrical surges, typically resulting from
lightning strikes, are very destructive to telephone equipment connected to AC power sources. To
minimize damage from these types of surges,
a surge protector is recommended.

FCC Information and CSA Information

The FCC Wants You To Know

In the unlikely event that your phone causes problems on the phone line, the phone
company can temporarily discontinue your service. If this happens, the phone
company attempts to notify you in advance. If advance notice is not practical, the
phone company notifies you as soon as possible and advises you of your right to file a
complaint with the FCC.

Also, the phone company can make changes to its lines, equipment, operations, or
procedures that could affect the operation of this telephone. The telephone company
notifies you of these changes in advance, so you can take the necessary steps to

ENGLISH

prevent interruption of your telephone service.

This equipment complies with the limits for a Class B digital device as specified in
Part 15 of FCC Rules. These limits provide reasonable protection against radio and TV
interference in a residential area.

However, your equipment might cause TV or radio interference even when it is
operating properly. To eliminate interference, you can try one or more of the following
corrective measures:

• reorient or relocate the receiving antenna.

• increase the distance between the equipment and the radio or TV.

• use outlets on different electrical circuits for the equipment and the radio or TV.

Consult your local store if the problem still exists.

Lightning

Your telephone has built-in lightning protection to reduce the risk of damage from
surges in telephone line and power line current. This lightning protection meets or
exceeds FCC requirements. However, lightning striking the telephone or power lines
can damage your telephone.

Lightning damage is not common. Nevertheless, if you live in an area that has
severe electrical storms, we suggest that you unplug your phone when storms ap­proach to reduce the possibility of damage.
