Cautions AVOID storing the radio under the sunshine or in hot areas. High temperature can shorten the life of electronic devices, and warp or melt certain plastics. AVOID storing the radio in the dusty, dirty areas. PLEASE keep the radio dry. Rainwater or damp will corrode electronic circuits. NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury. USE DC power supply, take notice of power voltage must be 13.8V only.

Operation Modes There are four types of operation mode . 1. VFO mode (Frequency mode): This mode shows only frequency on the display. All menu settings will be changed & stored as the latest value permanently, after pressing . 2. Channel number mode: At this mode, all settings are done through PC programmer. The user is not allowed to change any settings of the radio. 3. Channel+Frequency mode: At this mode, frequency and channel number are shown on LCD.
Basic Operation • Turn The Radio On & Off Press the power knob to turn the radio on. Hold power knob for 3 seconds to turn it off. • Adjusting Volume Press power knob once, LCD display will appear ”SET VOLUME” , turn the knob clockwise to increase volume or counterclockwise to reduce it. • Change Operation Mode Press on the front panel or on extended DTMF microphone to toggle between either VFO mode (frequency) & Channel+Name Tag mode, or VFO & Channel+Frequency mode.
• Scan RM-03 allows optionally looking for carrier or carrier with CTCSS or DCS. Your dealer can program those channels to be scanned on the scan list. Frequency/Channel Scan (Carrier Scan) Press button repeatedly until LCD shows “FREQ/CH SCAN?”, then press button to begin scanning per frequencies or per channels. During scanning, press UP/DOWN button on the Mic or rotate power knob to change scanning direction; press any button to stop scanning. (except button).
• Transmitting Before transmitting, it is recommended to monitor the channel you are using to ensure it is not busy by pressing button or Moni button on extended microphone. Then, keep pressing PTT button and start talking at approximately 2 inches from the Mic hole. During transmitting, the LED on the front panel will glow red. Release PTT button when you have finished talking.
You will receive only messages coming from those parties sending a proper TX signaling. (By this way, more radios share the same frequency.) If an incorrect code or no code is received, LED glow green but squelch will still remain mute. Advanced Manual Operations • Editing A Channel 1.
