INTRODUCTION

This Manual describes the operation for the RELM RM Series mobile radios.

The RM Series is full-featured FM transceivers designed for flexible mobile and base station business communications in the VHF or UHF Land mobile frequency bands.

The RM Series mobile radios can be programmed with 128 channels. The RM Series include a 16 segment, 8 character, alphanumeric display for channel display. The channel frequency data is stored in an EEPROM and flash memory; thus, allowing the RM mobiles to be easily programmed by dealers using personal computers with the PC editing software.

FCC Requirements - RF Radiation Exposure-for Occupational Use Only

Your radio must be properly licensed by the Federal Communications Commission prior to use. Your RELM Communications dealer can assist you in meeting these requirements.

Your dealer will program each radio with your authorized frequencies, signaling codes, etc., and will be there to meet your communications needs as your system expands.

CAUTION

To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines.

Antennas used for this transmitter must not exceed an antenna gain of 3dBi. The radio must be used in vehicle-mount configurations with a maximum operating duty factor not exceeding 50%, in typical push-to-talk configurations. This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted occupational use, work related operations only where radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation distance of 2 feet (0.7meters) between any persons and the antenna. Failure to observe these restrictions will result exceeding FCC RF exposure limits.

Do not operate the radio without a proper antenna attached. As this may damage the radio and may also cause to exceed FCC RF exposure limits.

Always use authorized accessories.

BASIC OPERATION

Important! - Before switching on the radio the first time, verify that the power connections have been made correctly and that a proper antenna is connected to the antenna jack.

Your authorized Dealer can program your radio to meet you communication and operational requirements.

RECEIVING

Switching Power ON

Turn power on by the VOL/PWR knob. The radio will beep, and become illuminated.

Press the UP/DOWN button to choose the desired operating channel. A channel name will appear on the display.

Setting the Volume

Turn the VOL/PWR knob clockwise to increase the volume, and counterclockwise to decrease it.

Selecting a Channel

Press the assigned PF (Programmable Fonction) button to increment or decrement the channel.

The display can show channel numbers or channel labels. The dealer can program the channel label as well as the channel information.

TRANSMITTING

Before transmitting, make sure there is no channel activity. Channel activity can be monitored by pressing the preprogrammed monitor button.

When receiving a call, transmit only after the incoming call ends. The radio cannot receive a call and transmit simultaneously.

Press the microphone PTT switch.

If the channel is clear, the BUSY/TX indicator will be red. The radio is now transmitting.

While holding in the PTT switch, speak across the face of the microphone in a clear and normal voice. For best transmission, hold the microphone about 1-1/2 to 2 inches away from your mouth. Release the PTT switch to receive.

7

If the Busy Channel Lockout feature has been programmed on a channel, the radio will not transmit when a carrier is present. Instead, the radio will generate a continuous lowpitched tone while the PTT switch is pressed. Release the PTT switch and wait for the channel to be clear of activity.

If CTCSS (Continuous Tone Code Squelch System) or DCS (Digital Code Squelch)

Lockout has been programmed on a channel, the radio can transmit only when there is no carrier being received or when the carrier being received includes the correct CTCSS tone or DCS code.

Time-Out Timer

If the selected channel has been programmed for Time-Out Timer, you must limit the length of each transmission. While transmitting, a beep will sound 10 seconds before TX time-out.

Another beep will sound just before the TX time out. The TX indicator will disappear and the transmission will cease at the TX time out. To resume transmitting, you must release the PTT switch and wait for the "penalty timer" to expire. If you press the PTT switch before this timer expires, the timer restarts and you will have to wait another "penalty" period.
