CAUTION - DANGER!!
The Zephyr’s power fuse is located inside the box, on the power supply module.
To change it, you will have to remove the top cover. Be sure to remove AC
power before opening the unit.
For continued protection against fire, replace fuse only with same type and
value.
If fuse replacement is required, please note: For continued protection against fire,
replace fuse only with same type and value. See the section Gaining Access for
information and important cautions.
Does the Xstream have any functionality?
Upon initial power‐up, the LCD shows "crosshairs", then briefly a black screen. Finally
the version and the Zephyr Xstream logo.
During the initializing period, a self‐test is performed. If there is a problem, this is
reported on the LCD screen and progress is halted. The entire message should be noted
for discussion with Telos customer support.
If the failure is does not involve a critical portion of the Xstream, you may be given the
option to "continue". We give this option for emergency desperation use only ‐ you will
need to determine if you unit will work for the intended purpose. You should have the
machine serviced as soon as possible if this happens.
If the unit does not reach the show the Zephyr Xstream logo and software version,
suspect a problem with the system processor, system clocks, or memory.
If the "Crosshairs" are showing on the LCD screen, it may mean that the front panel and
the main board have lost communication ‐ possibly because the main board processor
rebooted for some reason. Or, possibly because the main board did not boot up. In the
former case, the unit may be able to accept calls and connect without front panel
functionality. In that case, you may be able to use one of the remote control options to
control the unit until the unit can be repaired.
