12.7.­ TOT(TRANSMISSION TIMER):
This function can automatically control the time we transmit each time you press [PTT] on the transceiver. This
feature is very useful to avoid overheating excessive power transistors of the transceiver. The transceiver will be
off transmission automatically once the set time.
12.8.­CTCSS/DCS:
In some cases only want to establish communications in a closed user group at a particular frequency or
channel, for it will use "CTCSS" or code "DCS" for reception.
The "squelch" opens only when receiving a frequency with "CTCSS" or codes "DCS" same as the
programmed in your transceiver. If codes of the received signal differs from those programmed in your
transceiver, the "squelch" will not open and the received signal can be heard.
Note:
- The use of "CTCSS" or "DCS" in a communication, does not guarantee complete confidentiality
communication.
12.9.­ ANI
‐ANI (Automatic Number Identification) is also known as PTT ID because an ID is transmitted when the PTT
button of the radio is pressed and/or released. This ID tells the dispatcher which field radio was keyed.
Only could be set by PC software.
12.10.­ DTMFST (DTMF TONE OF TRANSMITTING CODE ):
First you should set the PTT‐ID as BOT/EOT/BOTH
‐"OFF"—Under transmitting mode, you can't hear the DTMF tone, while you press the key to transmit
the code or code automatically transmitted.
‐"DT‐ST"—Under transmitting mode, you can hear the DTMF tone, while you press the key to transmit
the code.
‐"ANI‐ST"—under transmitting mode, you can hear the DTMF tone, while the code automatically
transmitted.
‐"DT‐ANI"—under transmitting mode, you can hear the DTMF tone, while you press the key to transmit
the code or the code automatically transmitted.
12.11.­ SC­REV(SCAN RESUME METHOD):
This transceiver allows you to scan memory channels, all the bands or part of the bands.
When the transceiver detects a communication, the scan will stop automatically.
