Lectrosonics CR185 - Manual (Page 6)

RECEIVER REAR PANEL
12 VDC INPUT
Connects to the supplied CH-12 AC adapter for powering the receiver from a 110/120V AC source. The
receiver may also be powered from external 12 volt DC sources using the correct plug (Switchcraft
S-760 power plug). A diode bridge is used in the external power input, so that the CR185 will operate
properly from either polarity.
AUDIO OUTPUT
Supplies a balanced, low impedance output at microphone level. The audio signal is output on pins 2
and 3, while pin 1 is ground. The output level of this jack is controlled by the OUTPUT control on the
front panel of the receiver. The connector is a standard XLR type.
BATTERY REPLACEMENT
The CR185 is powered by a standard alkaline 9 volt battery. It is important that you use ONLY an
ALKALINE battery for longest life. Standard zinc-carbon batteries marked "heavy duty" or "long-lasting"
are not adequate. They will provide only about one hour of operation. Similarly, nicad rechargeable
batteries give less than 2 hours of operation, and will also run down quite abruptly. Alkaline batteries
provide about 5 hours of operation.
To open the battery compartment, press outward on the cover door in the direction of the arrow as
shown in the drawing. Only slight, sliding pressure is needed to open and close the battery door.

Swing the door open and take note of the polarity marked inside showing the location of the positive (+)
and negative (-) terminals. Insert the battery and close the cover by pressing in and across, reversing
the opening procedure outlined above. Note that the battery door will NOT close if the battery is
inserted incorrectly, since the terminals will hit a protective polarity barrier. Do not force the battery in.
