SAFETY INFORMATION

The Federal Communications Commission (FCC),

with its action in General Docket 79-144, 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 Communication Commission limits.

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.

DO NOT operate the radio near unshielded electrical

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

DO NOT operate the radio unless the antenna

connector is secure and any open connectors are properly terminated.

DO NOT allow children to operate transmitter-

equipped radio equipment.

This device complies with Part 15 of the FCC

rules. Operation is subject to the condition that this device does not cause harmful interference.

Page 7

BATTERY CHARGING AND CARE

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 battery loose in your pocket or purse. Do not attempt to repair battery.

The product you have purchased contains a rechargeable battery. The battery is recyclable. At the end of its useful life under various state and local laws it may be illegal to dispose of this

proper disposal in your area. Call Toll Free 1-800-8BATTERY for information and/or procedures for returning rechargeable batteries in your state.

battery into the municipal waste stream. Check with your local solid waste officials for details concerning rec ycling options or

Your radio comes supplied with one 7.5 volt 1100 mAh Ni-Cd battery pack, which can be recharged from 500 to 1000 times before requiring replacement. The actual number of charge / recharge cycles vary depending upon usage. We r ecommend that the battery

Page 8

be charged 14 to 16 hours on the first charge cycle and then in accordance with 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 correc tly installed.

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

1. 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".

2. Use the battery soon and use as much of the battery

capacity as possible or practical. A battery that is

charged and discharged com pletely will maintain the

Page 9

longest running time capacity. Also, several

charge/discharge cycles are recommended to bring

a new battery up to its rated capacity.

3. Store and charge the batteries at room temperature

65°F to 75°F. Batteries that have been stored for

over a month should be recharged before putting into

service due to chemical s elf-discharge which occurs

at a rate of approximately 1% per day. Do not charge

cold batteries (40°F or below).

4. 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 instrumentation loses all power,

then fully recharge and discharge again. Repeat this

cycle 3-4 times.

EXTENDED OPERATIONS

When operating in "Fr inge Areas" at some distanc e 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 mak e significant signal str ength changes. Finding the best location can also be done

Page 10

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 entir ely. 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 trans mitters 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 the FCC license application (Form 571), c all 717-337-1212 for additional information 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

Page 11

adjustments m ay result in illegal em iss ions, including of ffrequency 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 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.

ALERT TONES

The radio generates a number of alert tones to indicate various events. The f ollowing section describes the alert tones.

STANDARD TONES

Power-UP If programmed, a tone will sound on

power-up after the radio passes the self test.

Low Battery A low pitch tone will sound every 130

seconds when the battery is low and needs charging.

Carrier Control Timer

The Carrier Control Timer (CCT) alert is a pulsed tone signal that sounds whenever the PTT button is continuously pressed for a preprogrammed length of time. After nine seconds of pulsing the transmitter shuts down and communications is interrupted. To maintain communications, 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.

Call Received If programmed, a single alert tone

Call Queued (EDACS)

If programmed, a short tone is sounded whenever the Push-To-Talk (PTT) button is keyed and the radio has acquired a channel. This tone indicates the user may proceed to talk.

If programmed, a three tone alert is sounded whenever the Push-To-Talk (PTT) button is keyed and the radio has acquired a channel. This tone indicates the user may proceed to talk.

sounds when a group call is rece ived and a two tone alert (one high followed by one low tone) is sounded for an individual call.

If one short, high pitched tone sounds after the transm itter is k eyed, this indicates that the system has placed the request in a queue. This 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 becomes available. (See

Page 23

hear three short, medium pitched tones, this indicates that the receiving party is already engaged in another call or the system is busy and its queue is full. You m ust rek ey later to access the system.

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

Call Denied (EDACS)

A single low pitch beep will sound when the PTT switch is keyed and the request is denied by the system. This happens if the unit is an invalid user or if the unit is requesting an

Page 24

unavailable service.

Out of Range/ System

EDACS - A single pitched tone will sound immediately after the PTT switch is keyed indicating the radio is out of range of the repeater. The radio tries to place the call f or a s hort 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 rage, and these tones are heard.

GE-MARC - Five beeps will sound shortly after the PTT switch is keyed when the radio is out of range of the repeater or the radio is inoperative. If the “Call Retry” is active, the radio will try the channel at twenty second intervals for five minutes.

WIDE AREA AND PRIORITY SYSTEM SCANNING (OPTIONAL)

Radios operating within an EDACS system may be programmed for Wide Ar ea Scan operation for m ulti-site applications. Upon the loss of the currently selected system’s control channel, radios m ay be programmed to automatically scan other systems. If a new control channel is found, the radio will switch to the new system and sound and alert tone. Group selection may change upon switching to the new system.

The radio may also be programm ed for prior ity wide area system scan. A priority system may be assigned to each system programmed into the radio. Radios programmed in this m anner will scan the priority trunked

Page 41

system’s control channel once every one, two, three, or four minutes (programm able). This priority scan tim er is reset each time the PTT bar is pressed.

PROSOUND™ (OPTIONAL)

The radio may be programmed for ProSound s ystem scan operation for multi-site applications. ProSound scanning is an enhanced replacement for wide area system scanning. This algorithm insures that the radio continually receives high quality audio. When the selected system degrades to a pre-programmed level, the radio begins searching for the best adjacent system on a part time basis. Once a better system is found the radio changes to the new system and sounds a tone. should the control channel be lost com pletely, the radio will scan the adjacent systems until a suitable one is found.

DYNAMIC REGROUPING (OPTIONAL)

Dynamic Regrouping is a feature which allows the System Manger to dynamically program new groups into selected radios. Upon development of the regrouping plan, the site controller sends each radio the regroup plan number, “group position”, and activate/deactivate commands. W hen the radio is regrouped, it will alert the user and displays the regroup number “(nn = 01 - 08)”.

Page 42

NOTE

The regroup is identified by the leading zero in the 6th digit of the Display field. This zero is normally suppressed in Group 1-8.
