Basic Operating Procedures
Turn On the Radio
Basic operation is the same for all radio control heads. Control heads
with additional features are noted.
Do one of the following:
W4 Control Heads: Rotate the Volume knob clockwise.
W5 and W7 Control Heads: Press the power button in the
upper left corner of the control unit.
W9 Control Heads: Slide the power switch on the bottom of
the control unit to the left.
The display and graphics illuminate, indicating that the radio is
on.
When the ASTRO XTL 5000 Digital Mobile Radio is turned on,
the display shows
XTL 5000.
The radio then checks itself for problems.
Note: If
FL##/## (W4,W5,W7) or FAIL ##/## (W9) appears in the
display, the radio will not function until the condition has
been corrected.
If
ER##/## (W4,W5,W7) or ERROR ##/## (W9) appears,
some non-critical data has been changed. If either of these
displays appear, if the display goes blank, or if the unit
appears to be locked up, refer to the “Troubleshooting”
section.
