manual abstract
EXTENDED OPERATIONS When operating in "Fringe Areas" at some distance from the System, the other party may not receive your transmission clearly. Also, you may notice that the background noise will increase on received signals. Moving to higher ground or moving closer to the System will help alleviate these problems. If moving closer to the System is not practical, communication may be improved by moving away from shielding structures. If you are in a building interior, move closer to a window (preferably one generally in the direction of the System). At 800 MHz the wave length is very short, sometimes moving a few inches to a few feet can make significant signal strength changes. Finding the best location can also be done while listening to the background noise while moving about; attempt to find a spot where the background noise is reduced to a minimum or eliminated entirely. This may make the difference from not being heard, to being heard loud and clear when operating in the fringe areas of your System coverage. The fringe distance will vary greatly from plains areas, hilly terrain and mountain top sites. FCC LICENSING This unit may or may not require a specific FCC license to operate. The FCC requires all transmitters in the conventional and some Trunked Systems to be licensed by the Federal Communications Commission. Some Trunked operations are now exempt from individual licensing requirements but must be operated in a licensed System. Consult your dealer regarding specific licensing information, or contact the Federal Communications Commission. For more information regarding the FCC license application (Form 571), call 717-337-1212, or contact the FCC District Office nearest your location. TRANSCEIVER SERVICE There are no user serviceable components inside the radio. Altering the internal components or adjustments may result in illegal emissions, including off-frequency operation, or damage to the radio. Should an UNLOCK condition be shown in the LCD display, or the LCD fails to display information, or all icons and display segments are shown, turn the POWER ON-OFF/VOLUME control OFF then ON to reset the microprocessor. Ensure that the battery is fully charged and check that the antenna is securely tightened. If the unit still fails to operate properly, refer to an Authorized Service Center for servicing. INTRODUCTION This manual describes how to use the EDACS M-RK II Portable Radio. The M-RK II is a synthesized, microprocessor- based, high performance portable FM radio providing reliable two-way communications in both the Enhanced Digital Access Communications System (EDACS) trunking environment and conventional communication systems. In the EDACS or trunked system mode, the user selects a communications system and group. In this mode, channel selection is transparent to the user and is controlled via digital communication with the system controller. This provides advanced programmable features and fast access to communication channels. In the conventional mode, the user selects a channel and directly communicates on that channel. In this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair. The exact operation of the radio will depend on the operating mode, the radio’s programming, and the particular radio system. Most features described in this manual may be enabled or disabled through programming. Consult the system administrator for the particular features that are programmed into the M-RK II. USER INTERFACE The M-RK II operating controls are located on the radio’s front, top and left panels. A 15-button keypad, liquid crystal display (LCD) for radio status information, microphone and speaker are on the front panel. The top panel houses a rotary SYSTEM/GROUP/CHANNEL knob, POWER ON-OFF/VOLUME control knob and a protected red EMERGENCY button. An OPTION button, CLEAR/MONITOR button and the Push-To-Talk (PTT) button are all located on the left side panel. The Universal Device Connector (UDC) is located on the right panel and is used while programming the radio and for accessory connection. The keypad is used for manual number entry for individual calls, access to a telephone interconnect system, and activation of various EDACS or conventional features such as menu selection or scan operations. The display has two, eight-alphanumeric-character lines used to show the operational mode of the radio. Fifteen status indicators, used to indicate various operating conditions such as transmitter on, channel busy, scanning, or low battery, are located above and to the right side of the character lines within the display. A back light illuminates the display and the keypad for nighttime use.
