Portable PA System
Transmitter Operation
All portable PA/s equipped with a UHF wireless microphone module are compatible with the EJ-701TS handheld and
EJ-7LT / EJ-7XT bodypack transmitters. All transmitters could be sold separately.
1. Ensure microphone is switched off before inserting batteries.
2. Remove lower housing and battery clip. Insert 2 x AA batteries (alkaline or rechargeable's are recommended).
3. Press and hold the power switch for 2-3 seconds (located on the base of the microphone). The 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.
4. 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 stand-
by without switching the power off.
5. The LCD screen will display the channel selected. To determine which frequency this channel is operating on, press
the UP or DOWN frequency adjustment buttons.
6. Press the frequency set button for 1-2 seconds. The LCD screen will flash the currently selected channel number.
Your 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.
7. The battery status is displayed on the left of the screen. When battery capacity is critical the icon will flash 3 times
before switching the microphone off automatically.
8. To turn the microphone off, press the power switch for 2-3 seconds until the LCD screen displays "OFF".
9. When using with rechargeable NiMH batteries, connect a DC 5V plugpack 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 the 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: microphone is unable to be used during charge process.
