PRE-PROGRAMMED FUNCTIONS
The function selected by pressing and holding the DISP
button more than 2 seconds (but less than 4 seconds) can
be customized by dealer programming and your network
requirements. A brief explanation of available functions
is provided below. However, contact your dealer for de-
tails on their use and operation.
Low Transmit Power
This reduces the power output of your radio to ap-
proximately one watt to conserve battery life, and when
full power is not needed to maintain reliable communica-
tions. “LO ” will be displayed at the upper right corner
when enabled.
Alpha Tag
This displays an alpha-numeric channel name, usual-
ly describing the channel, rather than merely displaying
a channel number. These may be programmed to assist
you in recognizing channels by name, rather than by mem-
orizing channel numbers and their assignments.
Talk Around
This feature enables simplex operation on semi-duplex
channels: the transmit frequency becomes the same as the
receive frequency (regardless of any programmed offset
for the channel).
Note: This feature has no effect on simplex channels.
Optional Accessory
Voice Encryption (FVP-22):
When installed, pressing and holding this button more
than 2 seconds (but less than 4 seconds) will turn on the
optional voice encryption unit for privacy during com-
munications.
ENI (Emergency Numbering Identification)
Unit (FTE-19):
When installed, pressing and holding this button more
than 2 seconds (but less than 4 seconds) will turn on the
optional ENI Unit, then within 1/2 second, press this but-
ton again to transmit the ENI signal.
BUTTON FUNCTIONS
As mentioned before, button functions can be custom-
ized by programming from your Vertex Standard dealer
to meet your communications/network requirements.
Some features may require the purchase and installation
of optional internal accessories for operation. The table
below illustrates the possible Top-panel button program-
ming combinations. Functions are explained on the pre-
vious page “PRE-PROGRAMMED FUNCTIONS.” For further de-
tails contact your nearest Vertex Standard dealer. For fu-
ture reference, check the box next to the function that has
been assigned to the button on your particular radio, and
keep it handy.
CUSTO M SETTINGS
Below is a table of radio features that can be custom-
ized by dealer programming. To change a feature as your
requirements change, contact your Vertex Standard deal-
er. For future reference, check the box next to the option
that has been programmed in your particular radio, and
keep it handy.
