Base Tech II Base/Repeater Station Operator’s Manual

Emergency Caller Display
The Base Tech II Base Repeater has the ability to accept and display emergency calls from other radios within
the radio system.
This function is enabled by setting the <Emg Call Receive> field to "ON" in the <5Tone Decode Menu> or
<DTMF Decode Menu> during the programming of the radio.
The calling (Emergency) radio must encode its emergency data in the following format:
"000" + the calling radio's ID (decode number).
This format applies to both 5-Tone and DTMF signaling systems.
When the Base Tech II Base Repeater receives an emergency call, it will sound a warning tone from the
speaker. The LCD will display "EMG" (flashing) in the fourth line, and display the emergency radio's ID to the right
of "EMG" as shown below:
RX
TX
CH01
EMG 12346
Upon receipt of an emergency call, the Base Tech II Base Repeater will automatically respond to the emergency
radio by sending the emergency radio's ID number to it.
If the Base Tech II Base Repeater user presses the [#] key, the Base Tech II Base Repeater will resend the
emergency radio's ID number.
While the Base Tech II Base Repeater is in the Emergency Mode, all keys (except the [#] key) on the keyboard
become disabled.
Pressing the [SHIFT] key and the [
•
] key will return the Base Tech II Base Repeater to the normal operating
mode.
Automatic Transmit in Repeater Mode
The Base Tech II Base Repeater can be programmed to automatically repeat valid incoming messages. First,
the active channel of the Base Tech II Base Repeater must be programmed to operate as a repeater. It must
then receive a carrier frequency on the designated channel. If the Base Tech II Base Repeater has been
programmed for CTCSS or DCS operation, it must also receive a valid CTCSS or DCS tone. It will then
automatically retransmit any received signals.
When the Base Tech II Base Repeater ceases to receive a carrier frequency, or a valid CTCSS or DCS tone, it
activates the <Auto TX Reset Time> timer. This will keep the Base Tech II Base Repeater repeating (for up to
9.9 seconds depending on the programming of the Base Tech II Base Repeater), and allow other users with a
valid CTCSS or DCS tone to access the repeater.
