Pressing once turns the system ON and
lights the DCL system indicator. (Press-
ing again switches the system OFF.)
< When the offset is [S ](Simplex) >
3. Press the CHL key to start channel
linkage operation.
When the key is présséd office, the LCD
indicator flashes and the open channe!
range is scanned. (The frequency display
also displays the open channel being
scanned.) When an open channel is
found, the original operating frequency is
selected and data is automatically trans-
mitted for movement to the open chan-
nel.
lf the C.SQ system of the receiving sta-
tion is on, in conjunction with the DCL
system, you must ensure that the trans-
mit code is the same as his receive code
for proper system operation. If the
codes are the same the DCL system will
operate normally, ie. both radios will be
switched to the open channel.
4. When an open channel is
not found, press the PTT
switch or RESET key to
release the search.
2. if another station is trans-
mitting on the original fre-
quency when the unit re-
turns from the open chan-
nel search, automatic
transmission will not take
place. The radio will enter
a receive mode, in which a
series of three beeps
sounds repeatedly, while
normal receive functions
occur, As soon as the
channel is open you can
initiate the automatic fre-
quency change by simply
pressing the PTT switch.

When the key is pressed once, the LCD
indicator flashes and the open channel
range is scanned. {The frequency display
also displays the open channel being
scanned.)
When an open channel is found, the ori-
ginal operating frequency is selected and
the radio will enter a receive mode, in
which a series of three beeps sounds re-
peatedly, while norma! receive functions
occur.
As soon as the channel is open you can
initiate the automatic frequency change
by simply pressing and releasing the PTT
switch. (TM-3530A/2570A/2550A/
2530A only)
The TONE switch must be on for proper
operation. (TM-2550E only)
1. If an open channe! is not
found, press the PTT
switch or RESET key to
release DCL functions.
2, Channel! linkage does not
occur until the PTT switch
is released.
3. Just as when operating in
the simplex mode C.SQ.
system may also be used.
However, some repeater
systems may not pass the
DCL signal properly. This
is due to a time delay in
the repeater, and is nota
fault of the DCL system.
To move to an open channel during communication be-
tween stations A and B at 146.520 Mhz, proceed as fol-
lows. {In this example, 146.520 MHz is the frequency of
operation.)
The same procedure is used with the TM-3530A.
