4. Loud Speaker*
The receiver audio signals are heard from this speaker (provided that the volume setting is loud enough and
provided that the speaker has not been muted by one of the tone signaling formats).
5. Repeater Mode Indicator LED
The Repeater Mode Indicator LED will illuminate "REP" in
yellow
when the selected channel has been
programmed for Repeater operation. This LED is NOT illuminated on any channel that is programmed to
operate in Base mode.
6. Alarm Mode Indicator LED
The Alarm Mode Indicator LED will illuminate (Flashing) "ALM" in
orange
whenever the transceiver detects a
fault in the receiver module, the transmitter module, or the PA module on the selected channel.
7. Transmit Mode Indicator LED
The Transmit Mode Indicator LED will illuminate "TX" in
red
whenever the Base Tech II Base Repeater is
transmitting.
8. Busy Mode Indicator LED
The Busy Mode Indicator LED will illuminate "BUSY" in
green
whenever the Base Tech II Base Repeater
receives a carrier signal on the selected channel that is greater than the Squelch setting.
9. Keypad*
The 5 x 4 key Keypad is used to enter channel selection, tone information, and other data into the Base Tech II
Base Repeater. Specific key sequences are described fully in section 4 of this document. It includes the
following keys: CH, SCAN, MON, SHIFT, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0,
•
, #, A, B, C, and D.
10. Volume Control*
The Volume Control is used to set the audio output level from the loudspeaker. Rotate this knob clockwise to
increase the audio level, or counter-clockwise to reduce the audio level.
11. Squelch Control*
The Squelch Control is used to set the squelch threshold. Select a channel that is not being used and slowly
rotate this knob clockwise until the annoying background noise ceases. It may be desirable to rotate this knob
clockwise, slightly past the squelch threshold, to compensate for varying background noise levels.
12. Power ON/OFF Switch
The Power ON/OFF Switch is used to switch the Base Tech II Base Repeater "ON" or "OFF". Press this knob to
switch the Base Tech II Base Repeater "ON". Press this knob again to switch the Base Tech II Base Repeater
"OFF". This knob is slightly more depressed when in the "ON" position.
