Operation
Power & C arging Functions
The portable PA system is powered by 240 AC mains via IEC socket (see figure 2 for location) or via the internal bat-
teries. When operating for the first time the internal batteries will require charging for up to 8 hours. Charging will
occur whenever the unit is plugged into the 240 AC mains supply. The charge status indicator (shown in figure 2) will
illuminate red when charging. Once charging is complete the indicator will illuminate green.
When in use without mains power the LED built into the power switch provides indication of battery status:
100% to 20% capacity: red illumination.
<20% capacity: flashing red illumination
Level Adjustments & Input/Output Connection - Figure 3.
System inputs, outputs and levels can be controlled via this module. Master volume adjusts overall system level from
all inputs (ie: UHF, CD/MP3 player, RCA stereo input and wired microphones). Treble and bass controls affect all sys-
tem inputs. When set to half way sound equalisation will be flat.
RCA stereo jacks are provided for an external audio source. This allows connection of a CD player, iPod or other audio
source.
An RCA output is provided for use with external zone amplifiers or other PA systems if required. This output signal is
combined from all inputs (ie: UHF, CD/MP3 player, RCA stereo input and wired microphones).
Pressing the voice priority ( OX) button turns the voice priority on. The red LED will illuminate. This will mute music
output automatically when any microphones are in use.

Transmitter Operation
All portable PA’s equipped with a UHF wireless microphone module are compatible with the C 7192C, C 7193C
handheld and C 7195C beltpack transmitters. All transmitters are sold separately. See figures 8 and 9.
1. Ensure microphone is switched off before inserting batteries.
2. (Hand eld) Remove lower housing and battery clip. Insert two AA batteries
(alkaline or rechargeable’s are recommended).

3. (Hand eld)Press and hold the power switch for three seconds (located on the base of the microphone). he power
LED will illuminate red and “ON” will be displayed on the LCD screen. Note: power switch is more easily accessed
with lower housing removed.
(Beltpack) Slide the top mounted power switch to ON. he power LED will illuminate red and “ON” will be displayed
on the LCD screen.
4. (Hand eld) A selection switch on the rear of the microphone provides three level settings (mute, mid & high)
depending on the application or environment in which the portable PA is to be used. Mute setting allows microphone
to be put on standby without switching the power off.
(Beltpack) A selection switch on the side of the beltpack provides three level settings (low, mid & high) depending
on the application or environment in which the portable PA is to be used. he mute button allows beltpack to be put
on standby without switching the power off.
5. he LCD screen will display the channel selected. o determine which frequency this channel is operating on, press
the UP or DOWN frequency adjustment buttons.
6. Press the frequency set button for two seconds. he LCD screen will flash the currently selected channel number.
You can cycle through the channels by pressing the UP or DOWN frequency adjustment buttons. Press the frequency
set button again to lock in your channel selection.

times before switching the microphone off automatically.
8. (Hand eld) o turn the microphone off press the power button for three seconds
until the LCD screen displays “OFF”
(Beltpack) o turn the microphone off slide the power switch to the off position until
the LCD screen displays “OFF”
9. When using with rechargeable NiMH batteries, connect a DC 5V plugpack (Altronics M 8909A plus M 9187 tip
adaptor) to the charging port on the base of the microphone. Charging time is dependant on the capacity of
batteries used, typically 10-12 hours charging is required. If battery icon is flashing when charger is connected,
ensure rechargeable batteries are inserted in the microphone. If batteries have failed both the battery icon and
screen backlight will flash.
During normal charging the battery icon will cycle through the charge “block” icons. Once full capacity is reached the
full battery icon and all “blocks” will be displayed.
Note: microp one is unable to be used during c arge process.
