PUBLIC ADDRESS OPTION OPERATION
PUBLIC ADDRESS OPTION
If the Public Address Option is present, the radio may be
used as public address amplifier. Press the PA button to en-
able the option (Scan must be off). The LCD will show
"OPT" in the upper center portion of the display. When the
mic is keyed, the radio no longer transmits, but allows the
mic audio to feed the speaker. Adjust the VOLUME for de-
sired level. Press the PA button a second time to disable the
option. The OPT indicator will go out. Changing channels or
turning scan on will also turn the option off.
The Public Address microphone audio normally feeds an ex-
ternal speaker. An ON/OFF switch, which is mounted on or
near the radio, allows selecting either the internal or external
speaker for the receiver audio. The ON/OFF switch turns the
receiver audio on or off to the external speaker. This switch
still functions for the receiver audio with the PA option dis-
abled.
TYPE 99 OPTION OPERATION
If the Type 99 Option is present, individual selective calling
is possible. Press the T99 button to enable the decoder op-
tion. (Scan must be off). The LCD will show "OPT" in the
upper center portion of the display. When a call is received,
an alert tone will be heard and the OPT indicator will flash
continuously. After receiving the call, press the RESET but-
ton to reset the decoder for the Next call. The OPT indicator
will stop flashing.
To disable the decoder, press the T99 button while the OPT
indicator is on continuously. The OPT indicator will go out.
If a call was received and the OPT is flashing, the RESET
button must first be pushed before the T99 button will turn
off the decoder.
If the Horn Alert option is present with the Type 99 option,
the radio can beep the vehicle horn when a Type 99 call is
received. This option permits alerting persons out of the ve-
hicle when a call is received. The Horn ON/OFF switch
which is mounted on or near the radio, is used to turn off the
horn beep relay.
DETAILED TYPE 99 OPERATION AND
PROGRAMMING
The optional Type 99 Control Panels provide individual,
group, and super group call decode. The Motorola formatted
two-tone sequential signalling schemes can also be decoded.
In Type 99 tone systems, calls will not be heard from the
receiver until the proper two tones are detected. When the
second tone is decoded and recognized as correct, an alert
tone sounds during the remaining portion of the second tone.
The receiver audio path opens and remains open to receive
messages until the decoder is reset. The OPT indicator will
also flash to show a call has been received.
The MVS radio can be PC programmed with up to three
separate tables of tones. Either the EGE Type 99 format or
the Motorola format can be assigned to each tone table. The
tone decoder can be enabled individually for each channel.
Once enabled, one of the three tone tables can be selected
for each channel. After choosing a tone table, the call for-
mats must be specified: Individual, Group, and Super Group
for the EGE format or Individual, Group, and Quick Call for
the Motorola format.
The Group Call format allows communication with all
radios within a subgroup. The Super Group Call (in EGE
tone systems) or Quick-Call (in Motorola tone systems) al-
lows communication between all radios in a system.
EGE TYPE 99 FORMAT
Tone frequencies in the EGE tone system fall within the
range of 517.5 to 997.5 Hz.

A round-off error will occur when entering the tone fre-
quencies. This error is less than 0.2% and will not
cause any decoding problems. For example, if the
standard tone frequency of 517.5 Hz is entered, the ac-
tual decoder frequency will be 517.4 Hz. This new fre-
quency will appear on the screen in the tone tables.
