Fuse Replacement

The fuse in the fuse holder in the power cable protects the equipment from high elec-
tric current and equipment fault. If you cannot turn on the power, check the fuse to see
if it has blown. Find the reason for the blown fuse before you replace the fuse. If the
fuse blows again after the replacement, contact your dealer for advice.

When a magnetron reaches the end of its life, targets do not appear on the radar dis-
play. If long-range performance appears to have declined, contact your dealer about
replacement of the magnetron.

The total time of power-on ("ON TIME") and transmission ("TX TIME") are displayed
on the radar screen during the stand-by mode.
LCD
The life of the LCD is approximately 18,000 hours for the TZTL15F, and 25,000 hours
for the TZTL12F. The actual number of hours depends on ambient temperature and
humidity. When the brilliance cannot be raised sufficiently, contact your dealer about
replacement of the LCD.
Fan
The approximate life of the fan is as shown in the table below, and the actual life de-
pends on ambient temperature. When the fan does not rotate sufficiently, an applica-
ble message appears in the status bar. Turn off the power and contact your dealer
about replacement of the fan.
