Additional Information; Headset Operation - VTech vt2498 Operating Instructions Manual

Headset Operation

Your VT2498 Cordless Handset is equipped with a 2.5mm Headset Jack for
use with an optional accessory Headset for hands-free operation. If you choose
to use the Headset option, you must obtain an optional accessory Headset,
which is compatible with the VT2498.
To purchase a Headset, call VTECH Customer Service at 1-800-595-9511.
Once you have a compatible 2.5mm Headset, locate the Headset Jack on the
VT2498 Handset. Connect the plug on the Headset cord to the jack on the
cordless Handset. The plug should fit securely. Do not force the connection.
NOTE :
Whenever a compatible Headset is
connected to the cordless Handset, the
microphone on the Handset will be
muted. This is done to limit the effect of
background noise.
Many compatible Headsets have a
reversible, monaural design. You can
wear your Headset on either ear, leaving
one ear free for room conversation.
Belt Clip
The VT2498 is also equipped with a
detachable belt clip. Align the pins on
the inside edge of the clip with the
notches on the sides of the Handset.
The belt clip should snap securely into
place. Do not force the connection.
