VX-520U OPERATING MANUAL

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 program-

ming and your network requirements. A brief explanation of available func-

tions is provided below. However, contact your dealer for details on their

use and operation.

Low Transmit Power

This reduces the power output of your radio to approximately one watt to

conserve battery life, and when full power is not needed to maintain reli-

able communications. “LO” will be displayed at the upper right corner

when enabled.

Alpha Tag

This displays an alpha-numeric channel name, usually describing the chan-

nel, rather than merely displaying a channel number. These may be pro-

grammed to assist you in recognizing channels by name, rather than by

memorizing channel numbers and their assignments.

Talk Around

This feature enables simplex operation on semi-duplex channels: the trans-

mit 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 communications.

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 button again to transmit the ENI signal.
