Front Panel
POWER Switch
This is the main power switch for the repeater.
LED Indicators
AC: This LED glows green during AC operation.
DC: This LED glows yellow during DC operation.
MIC Jack
This 8-pin modular jack accepts the microphone in-
put, and provides a standby control line to activate the
transmitter when using the “BASE” mode of opera-
tion. This jack also provides a “Hook” control line, as
well as a “Clone Data” line.
BASE/REPEATER Switch
This switch toggles the operating mode between the
“REPEATER” mode and the “BASE” transceiver
mode. When the “REPEATER” mode is selected, the
LED above it glows green. While in the “BASE” mode
(the green LED is off), you can speak into the micro-
phone to use it as a transceiver. For normal repeater
operation, set this switch to the “REPEATER” mode.
LOCAL/REMOTE Switch
This switch toggles the control mode between the
“REMOTE” mode and “LOCAL” mode. When the
“LOCAL” mode is selected, the LED above it is off,
and the repeater operates according to the control data
programmed into the repeater. While in the “RE-
MOTE” mode, the LED glows green, and the repeater
operates according to the control instructions received
from an external device (connected to the ACC jack
on the rear panel).
MONITOR Switch
This switch selects the “Squelch” (receiver mute)
mode. When the green LED above it is off, “Tone” or
“Coded” squelch is active. When you press this switch
momentarily, the green LED will glow steadily; in this
condition, only “noise squelch” is active, and any sig-
nal present on the channel will be heard. If you press
and hold this switch for more than 2 second, the green
LED will blink and the squelch will open; in this con-
dition, background noise will be heard if no signal is
present.
ACCESSORY Switch
This switch can be set up for special applications, such
as High/Low power selection, as determined by your
Vertex Standard dealer. The LED above it glows green
when this function is activated. For further details, con-
tact your Vertex Standard dealer.
VOL Knob
This control knob adjusts the receiver volume level
from the front panel speaker. If desired, this control
knob may be set fully counterclockwise when repeater
monitoring is not needed.
SQL Knob
This control knob selects the noise squelch threshold
level. Set it to a position just above the point where
the BUSY lamp goes out when no signal is present.
Channel Selector Buttons ( and )
Press one of these buttons to select the operating chan-
nel.
Channel Indicator
This seven-segment LED indicates the operating chan-
nel number.
