Radio Operation; To Receive A Message; To Send A Message; To Place A Dtmf Call - Ericsson PCS Series Maintenance Manual

LBI-38957
Self-Test The radio performs a self-test at power-
up each time the radio is turned on. A
good (passed) self-test will be indicated
by three beeps, if programmed, fol-
lowed by the last radio status (channel
number, volume level, SCAN status,
etc.) being displayed in the LCD win-
dow. All segments of the display are
shown during the three beeps. If the
self-test fails, all segments will be illu-
minated but no beeps will be sounded.
BAT/ALERT Simultaneous flashing of BAT in the
LCD and the sounding of alert beeps, if
programmed, indicates failure of the
synthesizer to lock on frequency. If this
happens during transmission, the trans-
mitter will become inhibited and no
transmission will be made. The opera-
tor should select another channel, re-
charge the battery pack, or have the unit
checked.

RADIO OPERATION

This manual provides only elementary information re-
garding operation of the PCS personal radio. Refer to Op-
erator's Manual LBI-38955 for complete operating
instructions or Operator's Manual lbi-39133 for the 4-, 8-
and 16- channel version.

TO RECEIVE A MESSAGE

1. To turn the radio ON, slide the ON/OFF switch on
the battery pack to the ON position. A yellow-col-
ored area will be visible beneath the switch.
2. After the radio has passed the self-test, press and
hold the VOL UP (∧) or VOL DOWN (∨) button
while listening to the beeps (if this feature is pro-
grammed). Watch the LCD for the volume level
indicators (four bar lines) to select the desired lis-
tening level.
3. Press the CHAN UP or CHAN DOWN button to
select the operating channel.
4. The radio is now ready to receive messages.

TO SEND A MESSAGE

1. Turn the radio ON and select an operating channel
as instructed above in TO RECEIVE A MES-
14
SAGE. The current status of the radio is displayed
in the LCD window.
2. Press the MONitor button to determine if the chan-
nel is in use. Never interrupt another conversation.
3. While holding the radio so that the antenna is verti-
cal, press the PTT switch and speak directly into
the grill or across the face of the radio or external
microphone. Speak in a normal voice. Release the
PTT switch as soon as the message is finished.
Messages (responses) cannot be received when the
PTT is being pressed.
4. When transmission is desired on a paging channel,
the PTT switch must be pressed twice. Press the
PTT switch the first time to take the radio out of
the paging mode. Press the PTT switch a second
time for normal PTT operation. Remember that a
PG flag flashes in the LCD window and the radio
beeps on the first press of the PTT switch.
The radio can be returned to the Type 99 paging
mode by pressing the MONitor button.

TO PLACE A DTMF CALL

Specific procedures for placing a telephone call from a
PCS DTMF radio are determined by the operating system
where the radio is used. Consult a system representative for
the exact operating procedures for the system.
The keypad on the PCS DTMF radio is not active until
the PTT switch is operated. Therefore, the PTT switch must
be pressed at all times when operating any button on the
DTMF keypad.

OPERATIONAL FEATURES

The radio is PC programmable to power-up in either Se-
lective (paging) or Monitor mode for channels programmed
for paging.
When Selective mode is chosen, the radio operates as a
tone and voice receiver, and allows only those calls that are
tone coded for the radio to be heard. Selecting Monitor
mode allows all calls with the correct Channel Guard (if
programmed) on the channel to be heard.
In either mode, when a correct T99 and Channel Guard
(if programmed and enabled) have been decoded, a series of
intermittent beeps will be heard to alert the operator of an
incoming call. A slow flashing PG flag will be illuminated
on the display to indicate that a call has been received.
