System setup
Select the "System setup" and press the "Ok" key in the "Operation setup" interface as shown below to access the
"System setup" interface. Two options, i.e. "Backlight status" and "Select timer plan", are available in this
interface.
Ø Backlight status: This option can be set to "Always" or "Auto". If the "Always" is set, the backlight is always on;
if the "Auto" is set, the backlight will be automatically off after a certain period of time, and can turn on again
when any key is pressed or a time schedule is executed.
Ø Select timer plan: The 1
weekdays of schedules are storable for each plan. After one plan is selected, all edition and change of a time
schedule are automatically saved in the schedule. Any one of the plans edited can be called for use.
Note: Before editing a time schedule, the schedule plan should be selected first.

Changing program in built in USB disk
The built-in USB disk is mounted on the small iron plate on the rear panel. To change the program in it, remove
the screws on the iron plate with a screw driver, remove the iron plate and the USB disk will be exposed. After
changing the program in the USB disk, reinstall the disk and mount the iron plate. To prevent unauthorized
removal of USB disk, seal the iron plate on the rear panel securely. Make sure that a program exists in the root
directory of the USB disk, and the MP3 program should be stored under the root directory.
10. Use of microphone
Please turn down the microphone volume before plugging the microphone plug.
The microphone jack supports a 6.35 mm microphone plug. The volume can be adjusted by the volume knob, and
should not be turned too high.
The MIC1 has the override function which enables the microphone to have the highest priority and suitable for
forced paging in case of emergency.
11. External audio source
To use an external audio source, connect the external source at the AUX1, AUX2 or AUX3 interface on the rear
panel. The AUX1 channel has the highest priority, which is recommended to be used for emergency signal. Since
the 3 AUX INs and 3 MIC INs use the same input channel, the volume of one AUX IN and MIC IN (e.g. AUX1
and MIC1) can be adjusted by one volume knob (e.g. AUX1/MIC1 volume knob). Whether the volume of the
AUX IN or microphone is adjusted depends on the corresponding selector switch on the rear panel, which also
determines type of input signal in the channel.
