GENERAL SET-UP AND CONNECTIONS
Uploading Zetron Configurations to the 8800
The 8800 allows for configuration files to be saved and recalled on the test set. These configuration files are
uploaded to the test set from a USB flash drive.
The 8800 configuration files are available from the Zetron website at www.zetron.com. The file can be
downloaded, then unzipped and copied onto a USB flash drive.
To upload a file from a USB flash drive, insert the USB flash drive into the USB port and go to Utilities, then File
Manager. Copy the Zetron folder from the USB flash drive to the /USER/SaveRecall folder. To recall setups, go to
Utilities then Store/Recall, then recall the selected file.
Please note that some of the setups that are recalled are generic and may need to be changed for your
specific receiver and transmitter settings.
The generic saved setups are as follows:
Audio = 1000 Hz @ 1.5 KHz deviation (for wideband set this to 3.0 KHz deviation)
CTCSS = 100.0 Hz @ 0.35 KHz deviation (for wideband set this to 0.5 KHz deviation)
NAC = 293
TGID = 1

The 8800 utilizes a touch screen user interface. The Launch Bar is accessed by touching the light grey bar at
the top of the screen. The primary operating modes of the 8800 are Generators, Receivers, Analyzers, Meters,
