     Tips: Repeat operations above; choose OFF to turn off dual standby. Under the menu model, dual standby turn off temporarily, and recover after exit.
• Voice Compandor
  Through this function, it can reduce noise of call effectively.
• DTMFST
  After it turns on, When the walkie talkie transmits, the speaker will send out the corresponding dual tone multi frequency sound. There are three modes for monitoring side tone: Button + ID code side tone, button side tone and ID code side tone.

• R-Tone
  Press PTT button to send tone while holding down side button to define 1 button. There are four tone tones, 1000HZz, 1450Hz, 1750Hz and 2000HZz, which can be selected through the menu or frequency write software.
• R-Code
  Used to extract the edited corresponding identity code group. The ID code group can be edited by frequency writing software. For editing method, please refer to DTMF editor description.
• Scan Mode
  There are three scanning modes: time scanning, carrier scanning and search scanning

1. TO, stay for a while after scanning the signal, and then continue scanning
2. CO, stop scanning after scanning the signal until the signal disappears
3. SE, the search mode scans and searches the signal and stays in the current channel

• ANI Match
  After turn on this function, the machine recognizes the effective identity code, the caller ID / GROUP / ALL/ CALL will be displayed on the screen. After the effective ID is recognized, the machine will turn on the horn and reset the effective TOT (5S). That is to say, ifa valid ID is recognized or a call is initiated actively, the horn can be turned on within 5S without ID recognition.
• Setting Methods of All Call / Group Call / Groups Call / Single Call
  At the same time of launching, directly input the call ID code on the keyboard. For example, all members in a certain place are divided into 6 groups and 2 groups. Each group has 5 members.

The member ID settings are as follows:

A Group			B Group
FirstTeam	SecondTeam	Third Team	Fourth Team	FifthTeam	Sixth Team
121	131	141	221	231	241
122	132	142	222	232	242
123	133	143	223	233	243
124	134	144	224	234	244
125	135	145	225	235	245

1. Only send the ID code, and only send the receiver's ID code when calling. Then the receiver's LCD will display "P: call" after identification
2. When sending the receiver's ID code + [*] + caller's ID code, the receiver will display "P: caller's ID code" on the LCD. For example: if A's ID 121, B's ID 123, then a sends 123 * 121, B shows P: 121, realizing personal call.
3. Send the first two numbers of the first group , then all members of the first group receive the signal, and after identification, it will be displayed as "P: group!" on the LCD to realize group call.
4. Send group A's first ID number , only all members of group A's three groups receive the signal, and the group call will be realized if it is displayed as "P: group!" on the LCD after identification.
5. Send any digit + + to call all members. After identification, the LCD displays "P: ALL" to realize all call.

Tips:

1. Only when turn onANI Match function, All Call / Group Call / Groups Call/ Single Call will be activated.
2. After ANI Match function is turned on, the speaker can only be turned on within 5 seconds after receiving the correct signaling code or active call.

• DTMF Editor
  This radio can realize fast code sending by editing the stored ID code in advance. The editing method is as follows:
  Open DTMF editor of write frequency software, as shown in the figure, edit ID code you want to edit:
  
  Tips: When editing the ID code in the ID editor, you do not need to edit your own ID code; the receiver and sender' s own ID code must be set to three digits to realize the call display.

• PTT-ID
  PTT-ID refers to sending DTMF code edited in advance when PTT button is pressed for transmission. There are three modes of PTT-ID: code sending when PTT button is pressed, code sending when PTT button is released, code sending when PTT button is pressed or released.
• Alarm Mode
  In case of emergency, the alarm function can be turn on to remind the nearby personnel to be vigilant. Long press 2 seconds to define side button 1 to turn on the alarm function, repeat the operation or press PTT button to turn off the alarm. There are three alarm modes: sending alarm tone, sending alarm code and on-site alarm.

1. Send alarm tone: send alarm tone at the same time as the local alarm
2. Send alarm code: send the current stored ID code at the same time of alarm
3. On site alarm means that only the local machine sends out an alarm tone

• Tail
  Tail means that the speaker is mute after the end of the transmission; the closing Tail means that the other speaker makes a "click" at the moment of the end of the transmission
• OPENMGS
  It has three modes: preset icon, preset information and battery voltage. Preset icon and preset information can be edited by frequency writing software.
• Remote Stun
  At the same time of transmission, the signaling code is sent, and the other party is remote stun after receiving the code. The LCD screen displays "kiss", which cannot be received or transmitted.
• Canceling Remote Stun
  Only after receiving the canceling remote stun code can the machine be returned to normal use.
• Talk Around
  This function can be realized by defining side button2. After talk around is turned on, the current channel transmits at the receiving frequency. LCD display character "t" when the function is turn on.
• Reverse Frequency
  In standby mode, press button to tun on the reverse frequency function. After it is turned on, the transceiver frequency will be exchanged. That is, RX frequency becomes TX frequency, and TX frequency becomes RX frequency. When the reverse frequency is turned on, the LCD simultaneously displays "R".
