Cautions

AVOID storing the radio under the sunshine or in hot areas� High tem-

perature 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�

USE supplied microphone only� Other microphones have dierent pin

assignments and may damage the transceiver�

AVOID operating the transceiver without running the vehicle’s engine�

The vehicle’s battery will quickly run out if the transceiver is in transmission

while the vehicle’s engine OFF�

BE CAREFUL! The transceiver will overheat while operating con-

tinuously for a long period.

• Receiving

RM-03N can be programmed to work channel by channel in “Open

trafc” or “Group Mode”(CTCSS or DCS). Group mode prevents other

users on the same channel from being heard on your radio.

Open Trafc:

In this mode, you will hear all communication transmitted on the channel. When a message is received, radio’s squelch will be unmute and LED will grow green, and you will hear the message.

Group Mode:

CTCSS/DCS (Continuous Tone Code Squelch system / Digital Coded Squelch) are particular TX signaling as an access key to work a repeater (encoder) or to unlock the party signaling sensitive squelch. In group mode,

PAGE 9

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.

• Offset Direction Setup

This function should coordinate with the offset frequency setup, which enable you to communication with other transceivers through a repeater.

1. Press button to get into channel menu.

2. Press button repeatedly or press Up/Down key on extended

microphone till LCD shows “OFFSET”

3. Rotate power knob to select an offset direction

4. “OFFSET-”, indicate minus offset, TX frequency is lower than RX

frequency. When “Reverse” function is enabled, TX frequency will be higher than RX frequency.

PAGE 24

5. “OFFSET+”, indicate plus offset, TX frequency is higher than RX

frequency. When “Reverse” function is enabled, TX frequency will be lower than RX frequency.

6. “OFFSET OFF” means shut offset function off.

 Note: Offset function will be invalid when “Talk around”

function is enabled.

• Offset Interval Setup

12.5KHz.

• Reverse TX/RX

TX frequency turns to RX frequency & RX frequency change to TX frequency. The signaling will also be reversed if CTCSS/DCS signaling existed in this channel.

1. Press button to get into channel menu.

2. Press button repeatedly or press Up/Down key on extended

microphone till LCD shows “REVERSE”

3. Rotate power knob to set ON/OFF reverse frequency.
