6. Operating Instructions
6.1 Power On/Off and Volume Adjustment
- To power on, rotate the Power/Volume knob clockwise until a click is heard and the LCD illuminates.
- To power off, rotate the Power/Volume knob counter-clockwise until a click is heard and the LCD turns off.
- Adjust the volume by rotating the Power/Volume knob.
6.2 Frequency Selection
Use the up/down arrow keys or the numeric keypad to enter the desired 430MHz frequency. The step size can usually be adjusted in the menu settings.
6.3 Transmission and Reception
- Ensure you have a clear channel before transmitting.
- Press and hold the PTT (Push-To-Talk) button to transmit. Speak clearly into the microphone.
- Release the PTT button to return to receive mode.
6.4 VOX Function (Hands-Free Operation)
The built-in VOX (Voice Operated eXchange) function allows for hands-free transmission. When activated, the transceiver will automatically transmit when it detects your voice and switch back to receive mode when you stop speaking. Refer to the menu settings for VOX sensitivity adjustment.
6.5 CTCSS Tone Squelch
The DJ-S42 features 39-tone CTCSS (Continuous Tone-Coded Squelch System) squelch. This allows you to receive only calls from stations using the same CTCSS tone, reducing interference from other users on the same frequency. Configure the desired CTCSS tone in the menu.
6.6 Memory Channels
The transceiver has 100 memory channels where you can store frequently used frequencies and operating settings. Consult the menu guide for instructions on storing and recalling memory channels.

6.8 Scan Modes
Various scan modes are available to monitor frequencies. These include VFO scan, memory scan, and programmed scan. Activate scan modes via the function keys or menu.
6.9 FOX Hunting Feature
The transceiver includes a transmitter direction finding function with a 20dB attenuator, useful for FOX hunting (amateur radio direction finding). This feature helps locate hidden transmitters by reducing signal strength to pinpoint the source.
7. Maintenance
7.1 Cleaning
- Wipe the transceiver with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure the battery compartment and all jacks are free from dust and debris.
7.2 Battery Care
- To prolong battery life, avoid overcharging or completely discharging the EBP-60 Lithium-Ion battery.
