Press the assigned programmable key to activate the Talk Around feature when you
are operating on duplex channel systems (separate receive and transmit frequencies,
utilizing a “repeater” station). The Talk Around feature allows you to bypass the
repeater station and talk directly to a station that is nearby. This feature has no effect
when you are operating on “simplex” channels, where the receive and transmit fre-
quencies are already the same.
When the “TA” function is activated, the “ ” icon will be indicated on the dis-
play.
Note that your dealer may have mode provision for “Talk Around” channels by
programming “repeater” and “Talk Around” frequencies on two adjacent channels.
If so, the key may be used for one of the other Pre-Programmed Functions.

MERGENCY
The VX-4200 series include an “Emergency” feature which may be useful if you
have someone monitoring on the same frequency as your transceiver’s channel.
Press the assigned programmable key to initiate an emergency call. For further de-
tails contact your VERTEX STANDARD dealer.
CALL/RESET
This feature, if enabled, allows the user to change the 3-digit Page Call code, used to
call other similarly-equipped stations. Press the assigned programmable key, fol-
lowed by the three digits representing the Page Call code of the station you wish to
call. Three tones will be heard after the last key is pressed (the new code will now be
transmitted).
The receiver squelch of the other station will be opened, and you can begin commu-
nication.
