Operation Processes

Frequency and Channel Operations

• Frequency/Channel Adjustment: In frequency mode, adjust frequency or input directly via keyboard. In channel mode, use [Up Key] and [Down Key] to cycle through channels.
• Working Mode Switch: Press [Mode Switch] to cycle through Frequency Mode, Channel Mode, and FM Radio Mode.
• FM Radio: Access via [Menu Button] → [1FM] → [Up Key]/[Down Key] to select channel → [Exit Button] to exit.
• Frequency Scanning: Access via [Menu Button] → [2SCN]. Use [Up Key]/[Down Key] for up/down scanning. Press [Menu Button] to stop on the current channel or [Exit Button] to stop scanning.
• Frequency Reversal (Repeater Function): Access via [Menu Button] → [3REV]. This exchanges transmitting and receiving frequencies.
• Frequency Step Setting: Access via [Menu Button] → [9STEP]. Use [Up Key]/[Down Key] to select step values (2.5K, 5.0K, 6.25K, 10.0K, 12.5K, 25.0K, 50K). Press [Menu Button] to exit.
• Channel Memory Storage: Access via [Menu Button] → [4H/L] (This seems mislabeled, likely meant for channel storage or power setting). The text mentions "CH-MEM 001~128" indicating storage.
• Channel Deletion: Access via [Menu Button] → [5W/N] (This also seems mislabeled, likely meant for channel deletion or bandwidth setting). The text mentions "CH-DEL 001-128" indicating deletion.

Menu Function Setting

To set menu functions:

1. Press the [Menu Button] key.
2. Use [CH+] or [CH-] keys to select the desired menu item.
3. Press [Menu Button] key again to enter the item.
4. Use [CH+] or [CH-] keys to adjust parameters.
5. Press [Menu Button] key to save the setting.
6. Press [Exit Button] key to exit.

The number on the screen indicates the item number.

Key Menu Functions:

• [9STEP] Step Frequency Setting: Adjusts the frequency step (2.5K to 50K).
• [OSQL] Squelch Control: Sets the squelch level from SQ0 (open, with rustle) to SQ9 (most sensitive).
• POWER (High, Middle, Low): Sets transmit power output.
• W/NA (WIDE, NARR): Selects wide or narrow band working.
• COMP (OFF, ON): Enables/disables companding function for improved clarity.
• SRMR (OFF, ON): Enables/disables voice encryption (scrambler).
• SFT (OFF, ADD, SUB): Sets frequency shift for repeater operation. ADD adds shift, SUB subtracts shift.
• CTCSS (R-CTC, T-CTC): Configures Continuous Tone-Coded Squelch settings (OFF, standard series 67.0-254.1Hz).
• DCS (R-DCSN, R-DCSI, T-DCSN, T-DCSI): Configures Digital-Coded Squelch settings (OFF, standard series D023N-D754N or D0231-D7541).
• R-MOD (QT, QT+DTMF): Horn opens when CTCSS frequency matches (QT) or when CTCSS and DTMF match (QT+DTMF).
• CH-MEM: Channel memory storage (001-128).
• CH-DEL: Channel deletion (001-128).
• LED-SW (AUTO, ON): Controls backlight behavior (AUTO: off after inactivity, ON: always on).
• BEEP (OFF, ON): Enables/disables operation warning tone.
• RING (OFF, ON): Enables/disables calling warning tone. When receiving a matched signal, the machine sends voice, and the horn opens after voice timeout.
• BCL (OFF, ON): Busy Channel Lockout. OFF allows transmission on occupied channels; ON prevents transmission.
• TOT (OFF, 30S-600S): Transmit Time-Out Timer. OFF means no limit; otherwise, sets the maximum continuous transmit time (e.g., 120s).
• TONE (1000Hz, 1450Hz, 1750Hz, 2100Hz): Sets tone frequencies for activating relay stations when transmitting.
• DTM-TM (50MS, 100MS, 150MS, 200MS): Sets the interval time between DTMF codes when sending automatically.

• DTMF (8 sets): Predefined DTMF codes for transmission.
• ANI ID: Automatic Number Identification ID (set via frequency writing program).
• Dual Band Standby Switch (AB-SW OFF, ON): OFF for single band transmit/receive standby; ON for dual band transmit/receive standby.
• Operating Mode (MODE A&B-MODE, SCAN-MODE): Sets operating mode for A/B channels or scanning.

Diagrams and Visual Descriptions

Block Diagram (Page 1)

A diagram illustrates the basic connections of the transceiver. It shows inputs for a 13.8V DC power supply (positive and negative terminals), a hand microphone connection, and an antenna interface. The diagram implies these are standard connections for a mobile radio unit.

Rear Panel (Page 2)

The rear panel of the transceiver features the following interfaces:

• EXT.SP: External Speaker Interface: A 3.5mm single-channel plug can be connected here for improved audio output.
• 13.8V DC Power Supply Interface: Connects to a 13.8V DC power source. Ensure the red wire connects to the positive (+) terminal and the black wire to the negative (-) terminal.
• Antenna Interface: For connecting an external antenna with a 50 Ω impedance.

Remote Control Functions

These functions require the frequency writing program and setting an ID code. Different remote control functions require different control codes.

Setup Requirements:

• Open the frequency writing program.
• Connect the vehicle transceiver to a PC using a frequency writing cable (8-pin crystal head into the hand microphone port).
• Set the radio's ID code (main master code).
• Different remote control functions require different control codes.

Remote Functions:

• Alarm: Press [PTT] + 119 (alarming code), then release [PTT]. The controlled party alarms if the code matches. Adding master ID code at the end helps identify the source.
• Remote Stunning: Press [PTT] + #33 (stunning code) + [Master Control ID Code], then release [PTT]. Prohibits the controlled party from transmitting if codes match.
• Remote Shaking: Press [PTT] + #44 (shaking code) + [Master Control ID Code], then release [PTT]. Prohibits the controlled party from receiving and transmitting if codes match.
• Remote Monitoring: Press [PTT] + #22 (monitoring code) + [Master Control ID Code], then release [PTT]. The controlled party transmits automatically and starts monitoring for 7 seconds if codes match.
• Remote Reliving (Stunning/Shaking): Press [PTT] + #77 (opening code) + [Master ID Code], then release [PTT]. Relieves stunning/shaking functions if codes match.

Calling Functions (Requires QT+ANI mode):

• Individual Calling: Press [PTT], input the called party's individual code (e.g., 12345), then release [PTT]. Only the selected radio rings.
• Team Calling: Press [PTT], input [Team Number] + [*] (matching ID code length), then release [PTT]. Radios with the specified team number prefix will ring.
• Selected Calling: Press [PTT], input the called party's individual code from the keyboard (e.g., 12345), then release [PTT]. All selected radios will ring. (Note: This seems to overlap with Individual Calling description).

ANI Code and Control Codes:

ANI code is used for identification. Control codes (like #33, #44, #22, #77) must start with '#'. Master ID code must match the machine's ID code. Control code length should be 3-5 digits. If remote control is not desired, no control code needs to be input.
