EVX-S24 OPERATING MANUAL 15
OPERATION

The
EVX-S24
has two modes of DMR operation to
maximize spectrum efficiency. Standard operation
requires use of a TDMA repeater (such as the
EVX-
R70
) to utilize the repeater’s dual time slot capability
for doubling your radio fleet’s communication paths
for up to two simultaneous transmissions. The second
mode is Direct mode, which enables two communica-
tions paths on a single frequency, doubling your ca-
pacity with only the subscriber radios. No repeater is
necessary when operating in Direct mode.

If the BCLO (Busy Channel Lockout) feature has been
programmed on the channel, the radio will not transmit
when a carrier is present. Instead, the radio will gener-
ate short beep three times. Release the
PTT
switch and
wait for the channel to be clear of activity.

If the BTLO (Busy Tone Lockout) feature has been
programmed on an analog channel or CCLO (Color
Code Lockout) feature has been programmed on a dig-
ital channel, the radio can transmit only when there
is no carrier being received or when the carrier being
received includes the correct tone (CTCSS tone or
DCS code) on an analog channel or correct code on a
digital channel.

Turn the
VOL/PWR
knob fully counter
clockwise to turn off the
radio.
Automatic Time-Out Timer
If the selected channel has been programmed with an Au-
tomatic Time-Out Timer, any transmission is limited to a
fi xed transmit time, dictated when programming the radio
with CE157 software. A ten second warning tone/beep
will sound before Automatic Time Out Timer is expired,
with a second tone/beep sounding when the radio offi-
cially reaches the pre-set maximum transmission time. In
addition, the top panel red LED (“
TX
” indicator) light will
turn off and any transmission activity will stop. To re-
sume transmission, the user must release the
PTT
switch
and await expiration of the “penalty timer”.
