Fixed Mast Antenna; Xm™ Satellite Radio Antenna System; Chime Level Adjustment - Chevrolet 2007 TrailBlazer Owner's Manua

Fixed Mast Antenna

The fixed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is
still tightened to the fender. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear
of snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the best
performance from the XM™ system if the sunroof
is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Chime Level Adjustment

The radio is used to adjust the vehicle's chime
level. To change the volume level of the chime,
press and hold pushbutton 6 with the ignition
on and the radio power off. The volume level
will change from the normal level to loud,
and LOUD CHIME will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume
level will change from the loud level to normal,
and NORMAL CHIME will appear on the
radio display. Removing the radio and not
replacing it with a factory radio or chime module
will disable vehicle chimes.
