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 transmit-
ter 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 transmit-
ted 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 re-
ceived 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 loudness 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.
