SAFETY INFORMATION

The Federal Communications Commission (FCC), with its action in General Docket 79-144, dated March 13, 1985, has adopted a safety standard for the human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated equipment. Proper operation of this radio will result in user exposure far below the Occupational Safety and Health Act and Federal Communications Commission limits.

WARNING - DO NOT hold the radio in such a manner that the

antenna is close to, or touching, exposed parts of the body - especially the eyes or face - while the radio is transmitting.

WARNING - DO NOT allow children to operate transmitter-

equipped radio equipment.

CAUTION - DO NOT operate the radio near unshielded electrical

blasting caps or in an explosive atmosphere, unless it is a type specifically designed and qualified for such use.

CAUTION - DO NOT operate the radio unless the antenna connector

is secure and any open connectors are properly terminated.

This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

BATTERY CARE

WARNING

DO NOT dispose of the battery pack in fire - it may explode,

causing injury or death.

DO NOT replace the battery in hazardous atmosphere locations. DO NOT carry a battery loose in your pocket or purse. DO NOT attempt to repair battery.

RECYCLING/DISPOSAL OF BATTERIES

The U.S. Environmental Protection Agency (EPA) classifies used Ni-Cd batteries as hazardous waste, unless certain exemptions apply.

The battery should be recycled at the end of its useful life. Under various state or local laws, such batteries must be recycled or disposed of properly and cannot be dumped in landfills or incinerators.

Maxon America, Inc. fully endorses and encourages the recycling of Ni-Cd batteries. A national program to collect and recycle used Ni-Cd batteries is being implemented by the Rechargeable Battery Recycling Corporation (RBRC™). This program is being funded through the use of license fees paid by the battery and product manufacturers to place the RBRC™ Seal on the batteries.

The following is a list of facilities where the batteries can be shipped to be recycled. Contact these facilities for proper packaging and shipping guidelines.

(800) 548-8797

BATTERY CHARGING

Your radio comes supplied with a 7.5 volt 1100 mAh Ni-Cd battery pack, which can be recharged from 500 to 1000 times before it requires replacement. The actual number of charge/recharge cycles vary depending upon usage. We recommend that the battery be charged 14 to 16 hours on the first charge cycle, then according to the charger model instructions thereafter.

To remove the battery pack, push up on the battery latch and slide the battery pack to the right. To replace the battery, align the battery on the track and slide to the left until a click is heard, indicating the battery is correctly installed.

If the battery is to be charged on the radio, ensure that the power

BATTERY CHARGING, Continued

switch on the radio is in the off position before charging. Failing to turn the power switch to off during the charge cycle will result in a less-than-full charge condition, which will noticeably reduce the radio operating time between charges!

Normal battery operation time is 8 hours. This may vary depending upon how much the receiver audio is present and how much you transmit. The actual time may vary from day to day depending upon operational requirements.

For best performance:

• Charge battery to full capacity, 14 hours at the standard C/10 rate (capacity x .10). For "rapid" chargers, allow additional time (2-3 hours) for "topping off" the charge after it switches from "fast" to "slow" mode.

• Use the battery soon and use as much of the battery capacity as possible or practical. A battery that is charged and discharged completely will maintain the longest running time capacity. Also, several charge/discharge cycles are recommended to bring a new battery up to its rated capacity.

• Store and charge the batteries at room temperature (65o to 75o F). Batteries that have been stored for over a month should be recharged before being put into service (due to chemical self-discharge which occurs at a rate of approximately 1% per day). Do not charge cold batteries (40o F or below).

• Reduced capacity or "memory effect" may result from repeated identical shallow discharge/full recharge cycles. If such a condition is suspected, run the battery until the radio loses all power, then fully recharge and discharge again. Repeat this cycle 3-4 times.

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 the System will help alleviate these problems. If moving closer to the System is not

EXTENDED OPERATIONS, Continued

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 when 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 now are 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 Form 571 (FCC License Application) call 717-337-1212 or contact the FCC District Office near you.

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 window, or the LCD fail to display information, or all icons and display segments be shown, turn the 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

The Maxon EP-4800 Series EDACS Trunking Portable Radio provides reliable trunked communication in the 800 MHz band. Advanced dual format technology allows the radio to operate within the EDACS Trunked System and the GE-MARC Trunked System. The radio will also operate in a Conventional System.

The unit is lightweight and easy to carry. A backlit alphanumeric display provides clear visibility for low light or night-time operation.

This manual provides a separate section of operating instructions for each of the 3 systems (EDACS, GE-MARC, and Conventional). The Description section (which follows) and the Battery Information are applicable to all users.

connection within the service area.

ALERT TONES - STANDARD

The radio generates a number of tones to indicate radio status and condition. Both standard tones and those generated during trunked operation are described on the following pages.

Power-Up If programmed, a tone will sound upon power

up, after the radio passes the self test.

Low Battery A low pitched tone will sound every 130

seconds when the battery is low and needs charging.

ALERT TONES - STANDARD, Continued

Carrier Control The Carrier Control Timer (CTT) alert is a Timer pulsed tone signal that sounds whenever the

PTT button is continuously pressed for a preprogrammed length of time. After nine (9) seconds of signalling, the transmitter shuts down and communication is interrupted. To maintain communication, release and re-key the PTT switch. This resets the timer and turns the transmitter back on. The CCT is a built-in precaution against inadvertent use of the system.

ALERT TONES - TRUNKED OPERATION

Call Originate EDACS - If programmed, a short tone is

sounded whenever the PTT button is keyed and the radio has acquired a channel. This tone indicates the user may proceed to talk.

GE-MARC - If programmed, a three-tone alert is sounded whenever the PTT button is keyed and the radio has acquired a channel. These tones indicate the user may proceed to talk.

Call Received If programmed, a single alert tone sounds

when a group call is received. A two-tone alert (one high followed by one low tone) is sounded for an individual call.

Call Queued EDACS - If one short, high pitched tone sounds

after the transmitter is keyed, this indicates that the System has placed the request in a queue. The tone sounds at both the transmitting unit and the receiving unit(s), indicating to the user on the receiving end that they will receive a call shortly. If the PTT is unkeyed while in the queue, the radio will autokey (automatically key the PTT) when a channel is available.

ALERT TONES - TRUNKED OPERATION, Continued

Autokey EDACS - When the PTT is keyed to place a

call on the System, but the PTT is released before getting to the channel (e.g. a queued call), the radio will automatically key on the channel when it gets the assignment. The radio generates a long beep and holds the transmitter keyed for two seconds. Pressing the PTT button keeps the channel and sends the message before this two second time-out has expired.

System Busy EDACS - If you key the PTT button and hear

three short, medium-pitched tones, they indicate that the receiving party is already engaged in another call or the system is busy and its queue is full. You must rekey later to access the System.

GE-MARC - If you key the PTT button and hear a low frequency tone for 1 second, this indicates all channels are busy.

Call Denied EDACS - A single low-pitched beep will sound

when the PTT button is keyed and the request is denied by the System. This happens if the unit is an invalid user or is requesting an unavailable service.

Out of Range/System EDACS - A single pitched tone will sound

immediately after the PTT button is keyed, indicating the radio is out of range of the repeater. The radio tries to place the call for a short period (3 seconds) after the initial attempt. The radio generates a second low pitched tone when it gives up trying to place the call. The system is off the air or the radio needs servicing when the radio is within calling range, and these tones are heard.

ALERT TONES - TRUNKED OPERATION, Continued

Out of Range/System, GE-MARC - Five beeps will sound shortly Continued after the PTT button is keyed if the radio is

out of range of the repeater or inoperative. If the "call retry" is active, the radio will try the channel at twenty (20) second intervals for five minutes.

ERROR MESSAGES

SYN LOC If at anytime the synthesizer is unable to load

(Synthesizer Lock) and lock on the channel properly, this display

will be shown. If a SYN LOC message is displayed on all Systems, the radio has failed or has not been programmed properly. The radio buttons and keys will still operate.

PRS ERR If the personality has not been programmed (Personality Error) into the radio, this display will appear.

KEYPAD LOCK

The keypad can be locked at any time to prevent any undesired key presses. To lock the keypad when it is in the unlocked state, press the RCL key (LOCK) in combination with the Shift/Clear/ Monitor button. All buttons and keys except the PTT, HOME, SHIFT/CLR /MONITOR and LOCK will now be inhibited. To unlock the keypad when it is in the locked state, press the RCL key (combined with the Shift/Clear/ Monitor button) and release.

KEYPAD MUTE

The keypad can be muted at anytime. To mute the keypad when it is in the unmute state, press the STO key (MUTE) in combination with the Shift/Clear /Monitor button. All buttons will be muted. To unmute the keypad, press the STO key (combined with the Shift/Clear/ Monitor button) and release. The keypad is now unmuted.

SCAT OPERATION

A SCAT (Single Channel Autonomous Trunking) System operates with the same set of features as a standard EDACS system. The only user change relates to the BUSY indicator. Since only one channel, operating as both control and working channel, exists in a SCAT System, the BUSY indicator will be on when the SCAT channel is in the working channel mode. When the transmission on the channel is completed, the indicator turns off and indicates the return of SCAT control channel signaling.
