Busy lockout (settings menu: S08 BSY)
Transmit lockout when the channel is busy: For reducing interferences during radio communication,
a transmit lockout can be activated which blocks the transmission when the channel is busy. With
this function activated, transmission is also impossible when pressing the push-to-talk button.
DTMF (memory menu: M04 DTMF)
In CB radio, DTMF is used for controlling parrots and Internet gateways (depending on the features
of the used gateway software, DTMF can be used to switch e.g. into different virtual spaces) or
for applying a selective call procedure. Since the xm 4006e only features a DTMF encoder but
no DTMF receiver, the usage for selective calling is not possible with this radio set!
DTMF transmits the numbers 0 to 9, the letters A to D as well as the symbols * and # as tones
(known from tone dialing for telephone communications).
16 DTMF tone sequences can be stored in the xm 4006e. Common control commands are already
assigned ex works to all memory locations. However, the stored codes can be modified as required
(in memory menu under M04 DTMF: M01 to M16). Each memory location can be used for storing
a DTMF tone sequence with up to 16 digits.
Note: An already stored code can be overwritten. But if the new code is shorter than the previous
one, the previous tone sequence must be deleted before!
In the settings menu, one of the 16 DTMF memory locations can be assigned to the parameters
S10 BOT and S11 EOT (BOT = Beginning of Transmission, EOT = End of Transmission). When
a DTMF tone sequence is assigned to S10 BOT, this tone sequence is transmitted at the beginning
of each transmission, a DTMF tone sequence stored on S11 EOT is correspondingly transmitted
at the end of the transmission. The parameters CAL, BOT, and EOT can be separately stored
for each channel.
Storing a DTMF tone sequence
In the memory menu, select a memory location under parameter M04 DTMF by pressing the SET
key on the radio set/the SETbutton on the microphone.
Use the channel switch/the up/down key on the microphone to select the requested memory
location. Press the SET key once again: The required code can be entered now.
Store the entered code by briefly pressing the PTT button.
Deleting a DTMF tone sequence
In the memory menu, select the memory location to be deleted under parameter M04 DTMF by
pressing the SET key on the radio set/the SETbutton on the microphone. The first digit of the
code flashes.
Repeatedly press the A/F key on the radio set, until you reach the last digit of the code.
Repeatedly switch the channel switch, until a minus sign flashes on this position.
Use the FUNC key to move one digit to the right and repeat the procedure until you reach the
first digit.
Confirm deleting the memory content by pressing the PTT button.
A new value can now be stored to the memory location.
Transmitting a stored DTMF tone sequence
Set the DTMF/OFF switch on the microphone to OFF and press the B/CALL button: The display
shows CAL
and one of the 16 DTMF memory locations flashes. Use the channel switch or the
up/down key to select the requested memory location. Press the PTT button: The selected tone
sequence briefly scrolls over the display while being transmitted simultaneously. In this way,
stored DTMF tone sequences can quickly be transmitted as control commands.
Manual transmission of DTMF tones
Set the DTMF/OFF switch on the microphone to DTMF: During transmission, the DTMF tones
