your true wireless handsfree office solution!
Accutone is proud to introduce our DECT wireless headset conforming with the
standard 1.88~1.9GHz requirement. The WT99 wireless headset system is full GAP
compatible meaning it can be paired to any Wireless (GAP) PBx system. But aside
from being a stand-alone wireless headset, the WT99 can also be paired with any
fixed-line telephone by replacing its handset. Using the base station as a signal
transmission base as well as a charging unit, the wireless headset gives user true
mobility during phone calls. Paired with the optional automatic handset lifter users can
conveniently answer and end calls away from their desks.
Designed to meet the reliability requirements of a professional business product, the
WT99 is instead being marketed as an affordable product for the mass consumers as
well. This is because Accutone® believes that good product knows no boundary. With
long traditions of building headsets for the professional market, we not only have the
experience to build the best product in terms of acoustics, mechanics and cosmetics,
but also the ability to build product that is affordable to everyone.
So now, please spend some time to read through this entire manual to familiarize
yourself with this device, and again thank you for choosing Accutone® as your
telecommunication headset brand.

C. Setting up Handset Lifter
D. Adjusting Handset Lifter
First of all, connect the Lifter Plug
(W) into the Handset Lifter Jack (16)
located on the back of the base
Flip over your handset lifter, and you
will find two stickers, one vertical and
one horizontal.
Now test the lifter by wearing the headset and pressing the answer button
on the headset, if there’s no response or the headset hasn’t been charged,
please refer to the next section and come back to here afterwards.
If the handset lifts up and you can hear a dial tone, your lifter setup is
completed. But if lifter lifts up the handset but not enough for picking up the
line signal, you will need to adjust the lifting height as below:
Lift up the handset and carefully
remove the sticker seals and place the
lifter on top of the speaker area (as
shown below) of the telephone under
the handset.
Not all telephones have a large flat
surface or the speaker area may not be
directly below the handset.
If so, just find any way to fix the lifter
underneath the handset, and follow
the instructions about using an
external sensor in section E.
Locate the (S) Lifting Height Switch on the
front side of the lifter as illustrated. There
are 3 selection you can choose with the
top-most being the highest lifting distance.
As the weight and size of handsets vary
across telephones, you may need to use a
lower setting if the handset flies out of its
cradle due to its lightweight.
Rubber or Paper Pads.
But if even the highest setting is not
enough to lift the handset for picking a
line, try adding pads between lifter and
the telephone as shown below to
shorten the lift-distance.
The LED Indicator (T) lights up when
you press the Answer Button (2) on
your headset, indicating online status.

E. Using External Sensor for the Lifter
F. Removing and Replacing Battery
The internal sensor within the handset lifter is used to pick up the ring tone
of the telephone and transmit a signal to your headset so you know there’s
a call coming in while you are away from your desk.
But if the ringer speaker of your
telephone isn’t located below or
close to the lifter, you will need to
use the supplied external sensor.
The rechargeable battery of the WT99 headset is a detachable design and
can be replaced. It is a specific design and user should only use the official
battery supplied by Accutone. All rechargeable battery has a life-span and
should be removed from the headset during extended period of nonusage. Contact your reseller for replacement battery purchase details.

If for any reasons outside of the ones mentioned above, you still do not
receive any beep tone from your headset when the telephone is ringing, ie.
telephone ring volume too low...etc. Hook up the external sensor as
described and try speaking into the sensor with louder than normal
speaking volume, if this still doesn’t generate any beep tone, contact your
reseller or service center as the sensor may be malfunctioning.
