CONTROLS AND FUNCTIONS
CONTROL PANEL
WIRELESS MICROPHONE VOLUME
Turns unit power on and off and also functions as the volume control for the internal wireless receiver.
POWER
A red LED that lights when unit power is on.
RF
A green LED that lights when the companion transmitter is turned on and there is sufficient signal for good system
operation. Internal circuits monitor both signal level and interference levels and decide if the transmitted signal is
strong and “clean” enough for satisfactory operation. If not, the green RF LED will go out and the receiver will mute
the audio (“squelch”), turning off the sound output. This action is automatic and requires no user adjustment.
MOD LEVEL
The red and green MOD LEVEL LEDs continuously indicate the modulation level (audio level) of the received signal
from the transmitter and are used when making initial adjustments to the transmitter.
MIC
This connector is a standard 1/4" phone jack and is used for plugging in the cord from a low impedance dynamic
microphone.
LINE
This mini jack is used for connecting high level, high impedance outputs from tape decks or other amplifiers. It also
may be used for connecting the “earphone” output from portable cassette players.
AUXILIARY INPUT VOLUME
Adjusts the volume of the MIC and LINE inputs.
AUX IN/OUT
An RCA phono jack that functions both as a line level input and line level output. This “omnibus” jack is primarily
used for interconnecting several Long Rangers together for simultaneous operation. This jack can also be used with
a tape deck to either record from or play back into the Long Ranger. When used with a tape deck or other audio
source, the sound output level must be controlled by the volume control on the tape deck since there is no volume
control on the Long Ranger for the AUX IN/OUT jack. When an external device is connected to this jack, the loud-
ness of the Long Ranger will usually be reduced.
DCR15/2AU CHARGER
A special jack used for connecting the charger when charging the battery pack. The green LED located under the
jack lights when the batteries are charging. This LED automatically goes out when the batteries are almost fully
charged.
12V DC OUTPUT
A special jack used to supply power to the Add-On receiver when that option is installed.
