Base Station Level Confirmation
This operation allows the GTI unit to generate a tone into the associated base station for measurement purposes and allows
tone levels received from the base station to be viewed on the GTI Configurator's bar graph.
Move the highlighted cursor to a desired line and press the Enter key to see available selections on the pop-up window. To
start the base station level operation, choose the 'Master II Base' menu item.
You may select this item for any line type at any time, even in the middle of a call. Caution: If you turn on the test tone during

Level Set All Feature
This feature has been provided to allow the adjustment of the two audio level settings and two E&M 4-wire hardware gains
without having to access a line. It can be used to set the levels and gains in one set of operations.
This feature should not normally be used, however, it does provide security in case the level is adjusted too low to allow
normal calling to take place.
CAUTION
If you are currently making adjustments through the internal modem on the GTI unit, it is possible to adjust the levels low
enough on the line you are calling in on to make the modem lose carrier and disconnect the call. You may not be able to
access that line again without going to the system.
