The DTSS signal is not transmitted immediately after
you press the PTT switch. A programmable delay time
has been incorporated to allow the DTSS signal to be
passed by repeaters with slow response times. You can
select a delay time of 250 mS, 450 mS, 750 mS, 850 mS,
or 1 second.
When operating simplex mode the 250mS will
automatically be selected for you. No other choice is
available in this mode, even though you may have
selected a different delay.
In modes other than simplex you may select between the
remaining delay periods (450 mS, 750 mS, 850 mS, or 1
second).
NOTE
250mS cannot be selected for offset modes.
To select desired delay time :
1. Press and hold the F key, then press the DTSS key.
