Local/Remote Operation (Option 2 required)
The Low Cost Base Station can only be operated in the Remote mode if the transceiver is
ordered with a remote 9-pin connector (extra cost option) which is located on the side of the
transceiver chassis.
Base Stations which employ the Model TiL 91-DE/8.33 or the TiL-90-6R/8.33 transceiver operate in
local and remote modes simultaneously. Older 91-DE units employ a front panel switch for local or
remote selection.
1.
LOCAL OPERATION - In local operation, voice audio, and keying (PTT) functions are
routed from the microphone to the transceiver. Receive audio is routed to the internal
loudspeaker.
2.
REMOTE OPERATION - In Remote operation, transmit audio, keying (PTT), and receive
audio signals and others are available on the 9-pin "D" connector. See Table 1-2 for
remote connector signal details.
NOTE
In the 90-6R and 91-DE the audio and PTT signals are
connected in parallel. This allows the PTT and TX
audio to be functional on the 9-pin connector as well
as on the microphone connector. The RX audio is
routed to the internal speaker via the volume control
and to the 9-pin connector at a constant level.

AC and DC Operation
The unit can be operated by external 120 VAC or external 13.7 VDC battery power.
1.
AC OPERATION - During AC operation, the unit can trickle charge external batteries via the
+/- Battery connections located on the terminal block mounted on the rear of the SPG-010
Power Supply. The external battery ON/OFF switch must be in the ON position for these
functions to occur when an external battery is connected. A 220Vac version of the SPG-010
can be specially ordered.
