SET UP
For first time users of the GTX and GRX, allow some time to become familiar on how to navigate the
operation and setup menus before putting the equipment into “On Air” service.
Password Organization
As a factory default, the equipment is delivered without any access restriction. The passwords are
“OFF” in both the Transmitter and Receiver. The managing of the password function is optional and
we recommend its use only where needed
The password organization is set in 2 security levels, each with its own password. If password
management is desired, enable both levels. The higher Level 2, permits setup access and changes
while the lower Level 1 is restricted to monitoring only.
The password is 4 alphanumeric characters, including upper and lower case, plus several special
symbols. The complete password is masked by dummy characters “****" until the curser is moved to
each position for selecting the character and then reverts back to a dummy character when the
curser is moved to the next position. The correct or confirmed password is never shown unless an
incorrect password is entered.
The two levels are defined as follows:
Level 1: Lower security level
• If restriction is desired to prevent access to the Setup menus, then this Level can be set
to "ON”. With the Level 1 password enabled, the “Enter Password” field is activated
when navigation to the Setup menu is attempted. Failure to insert a correct password
will prevent access to Setup menu and a time-out, typically a length 3 minutes, expires to
return back to Operation menu.
• Again, the factory default is set to "OFF", and any user is permitted to freely navigate
through the equipment's monitoring menu information. We suggest leaving it in this
state if users are expected to access most of the monitoring and control menu fields.
Level 2: Service level
• This password is used for restricting access to make changes in the Setup menu, such as
frequency, RF power, audio input & output levels and other operating parameters.
• Its use is reserved to personnel who need wide access to the equipment setups and
functions. After installation and the equipment checked out is completed, it is
recommended to change the default factory state of "OFF" and enable the Level to ON,.

Factory Default Passwords
These are the two factory default passwords:
Level 1: P001
Level 2: P002
Be sure to enable and setup the 2nd Level if passwords are going to be used in your STL
system.
Display Menus and Navigation
Rotating the jog knob counterclockwise or clockwise will scroll up and down the menu displays or
within a field to view the submenus when a field is entered. A quick push or tap on the knob will
