number but must not be used as a PTT or Emergency ID on any
radio in the system. The default is 0 (zero) which effectively means
that there is no group call (only the all call).
GE Star® Selective Call to Unmute
This is similar to the MDC-1200® Voice Select Call. If this feature is
enabled, the radio will remain muted unless a GE Star® Selective
Call command is received.
DTMF PTT ID, Emergency ID
In DTMF signaling, the PTT ID and Emergency ID are different so
the base can determine what is an emergency message. Systems
with dispatch consoles generally define a DTMF PTT ID as a
number beginning with a 1 and Emergency ID’s begin with a 7.
DTMF character duration
This timer is active for PTT and Emergency ANI and DTMF Keypad
Auto transmit mode (25 mS through 1000 mS in 25 mS steps).
Each ANI character is generated for this amount of time.
DTMF inter-character duration
This timer is active only for PTT and Emergency ANI. The time
selected is the silent gap between individual DTMF digit
transmissions(25 mS through 1000 mS in 25 mS steps).
Enable Manual Keypad DTMF
If enabled, DTMF tones will be generated when keypad buttons are
pressed with the radio keyed. The associated tone continues to be
transmitted until the button is released. The radio microphone is
muted for the duration of the button press. Enabling this feature
and not designating ANI type for the channel will permit manual
DTMF generation without PTT ANI.
DTMF Keypad auto transmit
If enabled, the radio will automatically go into transmit and DTMF
will be generated when keypad buttons are pressed. ANI will not be
generated for any automatic transmit session. After a button is
released, the radio will remain keyed for one second to await further
button presses. The length of the transmitted DTMF tone is the
value programmed as ―DTMF character duration‖. The radio
microphone is muted for the duration of the function. If PTT ANI is
enabled, the ANI will be generated as programmed (beginning send
or end send) for radio PTT button presses.
Open Microphone Monitor on Man Down TX time
If not set to zero, once a Man Down is activated, the radio will key
up and transmit ambient noise for this period of time(0s to 55s, 5s
steps). It will then unkey and remain unkeyed for a programmed
amount of time and then repeat the process. It will alternate
between TX and RX throughout the Man Down cycle. The length of
the cycle is determined by the settings of ―Number of repeat Man
Down transmissions‖ and ―Time between Man Down repeats‖. If
the value is set to zero, there will be no open microphone monitor.
Open Microphone Monitor on Man Down RX time
If open microphone monitor on Man Down TX time is not set to
zero, the radio will remain unkeyed for this period of time between
TX times(0s to 55s, 5s steps).
