APP Operation

1. Download the APP
   • For Android users, please go to Google to search for HT to download the APP
   • For IOS users, please go to Appstore to search for HT to download the APP
2. User login
   • User registration: Click on the avatar to register the user, enter the registration page to modify user information, and signaling settings, and change the avatar.

Nickname: Nickname is used for radio and network channels, please fill in your name or callsign (support Chinese, English, and numbers), if you have obtained a legal call sign, please fill in the call sign.
Id signaling: This system uses self-developed signaling (BSS signaling system). If the APRS format is not enabled, the radio and network channel will use the BSS signaling system. Set the identity-related information sent by this device. When sending, the current channel must open the signaling function at the same time, and the relevant information of the radio will be attached after each transmission. If the signaling function is not enabled on the current channel, the recipient will not be able to see your device information.

• *  **Identification information –** When ON is active, others will receive your radio equipment identification information.

  • Location ——– When ON is active, others will receive your real-time location and the location-sharing function of the mobile phone must be turned on to take effect.
  • Allow checking —- When ON is active,, others will automatically find your location information without your confirmation.

Automatic location sharing: (through the BSS protocol, the APRS protocol will be used after APRS is enabled).

• Network share location — When ON is active, the radio will send real-time location information to the network channel according to the set interval.
• Radio sharing — When ON is active, the radio will send real-time location information to the selected radio channel according to the set interval.
• Interval time——- Please set the interval time for automatic location sharing according to your needs. The time cannot be set too short, otherwise, when multiple users use it at the same time, the channel will be occupied by data transmission for a long time, affecting communication.
• Send power voltage — When ON is active, others will know your phone battery level.
• Attached message column —– The information filled in here will be sent with the location information.
• Use APRS format — When ON is active,, automatically jump to the APRS setting page for related settings. (For APRS knowledge, please refer to related articles) BSS routing (acting on BSS protocol radio sending and receiving text messages and location-sharing functions)

TTL (time to live): It is the parameter of the machine as the sender, which sets the maximum number of times the data sent by the machine can be forwarded.
The maximum number of forwarding times: it is the number of forwarding times allowed as a router. Assuming that the maximum number of forwarding times of the router is set to 5 times, the received data packet has been forwarded less than 5 times, the router will forward it automatically. When the received data packet has been forwarded more than 5 times, it will stop forwarding because it exceeds the maximum number of forwarding times set by this router. But if there are other routers that allow forwarding, it will continue forwarding through other routers.

• The area indicated by the red box in (Figure: 6) displays the list of channels currently used by the bound device. Select this channel to switch to it.
• Output Power: Transmitting power of the current channel, switching between high and low power.
• Single CH: only monitor the currently selected channel.
• Dual CH: dual-channel monitoring, the cursor points to the channel as the main control channel (transmitting only works on the main control channel), move the cursor to switch. The main control channel is triggered by the received signal to automatically move the cursor to switch between the two pairs of guard channels. It can be switched manually in idle state. Turn on the dual watch, and automatically block the radio function.
• Scanning: On, the channels that have been allowed to scan in the channel list will enter the scanning state.
• FM Radio: Turn on the radio function, the device will automatically turn off the radio function when the call is busy, and automatically turn on the radio when it is idle. Click the radio icon to enter the radio operation interface.
• Talk Around: switch between talk around frequency and repeater frequency state (details in the edit channel section).
• Power: Turn on or off the power of the currently bound device. (This function is only applicable to the mobile radio)

Radio and Network Channel

• Binding of the radio channel and network channel: (Figure: 7-1) Long press the channel box to pop up a submenu to select the network channel to be bound, after the binding is completed.
• Dual-mode use of radio and network channel: (the analog channel must be bound with the network channel)
  • When using the mobile radio, only the wired microphone can be used for a dual-mode transceiver.
  • When using the handheld radio, press the PTT on the handheld radio can be used for analog and network dual-mode.
  • Note: The wireless microphone only works for radio transceivers. Only the radio channel interface can be used for dual mode when using the APP, and only the network channel is effective when operating on the network channel interface.
• The radio prohibits the transmission function. When the dual mode of radio and network intercom is used, the radio transmission function can be turned off as needed. At this time, press the PTT transmission button, and the walkie-talkie will only conduct intercom through the selected network channel. When the network signal is poor or disconnected, press PTT at this time, and the handset will emit a warning tone, indicating that the network intercom cannot be performed.

To enable relay mode, the bound network channel must be the owner of the network channel creator (director) or authorized administrator to have permission.
• (Figure: 7-2) The network channel creator (director) can authorize administrators to mute and delete team members.
• Remotely control the frequency of the local walkie-talkie: 2 Android phones are required to realize this function. The remote-controlled mobile phone must be the creator of the network channel. The local walkie-talkie and the mobile phone are bound to each other and enter the network channel created by the remote phone. Synchronize radio configuration needs to be checked, (Figure: 7-1) so that the remote creator only needs to modify the frequency of this network channel, and the frequency of the local walkie-talkie will change accordingly. (Figure: 4-2)
