Wireless
Headset
In a typical installation the
antenna is pointed directly
upwards as shown here
If the IM-977W4 must be installed
on a vertical surface, it is
recommended to fold the antenna
so the main shaft is vertical
The system will work
with the antenna
oriented horizontally,
but effective range will
be somewhat reduced
