OPERATION
1) Open the battery cover, in accordance with the correct polarity into 2*1.5V battery.
2) Press power switch, power lamp lighting then going out, it means that the receiver
is on normal working. If the red lamp always lighting and corresponding LCD
display BAT under 2 segments, it means that the battery is low and advise the user
to change the battery at once.
3) The receiver include voice again adjusting device can follow each person’s sound.
4) AF output selecting switch. According the use of AF output signal to select the line
output (high impedance, low level output) or earphone output (100mw, 32Ω low
impedance output), to make sure that the signal can be at it’s best and without any
distortion.
5) Channel frequency set: To facilitate the large number of users using the system, at
the first channel’s frequency need reasonable set by group. The same place can’t
use same frequency. Channel frequency set follow below: press SET key first
display screen digital lashes, then press Key until get to right frequency, then
stop press 5 second, the receiver will auto-save & lock the result of setup.
6) 2.4V charging connector, it is to charge for 2*AA 1.2V battery. Both save money
and easy to moving use. The charging time depends on it’s capacity, it is advised
to use the charging battery with 1500mAh. And it’s charging time is 10-12 hours.
NOTES OF OPERATION
1
)
The battery working time is depend on earphone output volume be coming higher,
the current consumption will be more, the battery working time will be less. So
please select the earphone with high sensitivity, it is more better to over 110dB/MW.
2
)
If it is not used for long time. Please take out the batteries to avoid the battery
leachate to mar the inner circuit or accessories.
