Connection and operation
The unit may arrive with the internal battery already charged. Before connection to the mains, switch the unit On and see if the
Power LED indicator lights up. If it doesn’t you will need to charge the battery before you can use the unit without it being attached
to the mains (see How to charge the battery below). Always use an appropriate IEC mains lead (supplied).
How to charge the battery
Kam RZ12A Portable PA-BT If the unit is connected to the mains but not in use and the power switch is in the Off position, the
internal battery will be re-charged from the mains supply. This is shown as the Battery charging indicator LED will be lit when
charging. When fully charged, the light will go out.
Kam RZ15A Portable PA-BT The unit’s battery indicatators are at the top of the unit next to the media player. There you will see a
Full Batt(ery) LED indicator and a Low Batt(ery) LED indicator. When the unit needs to be charged, connect it to the mains, turn the
power on and ensure that the Battery charger on/off button is turned to On.
Before operation ensure that the volume controls, the echo controls and the mic volume controls are all turned fully anti-clockwise.
The unit is now ready to use.
VHF wireless system
Insert the batteries into the handheld microphone (ensure that the terminals of the batteries match to the mics to observe the correct
polarity). With the Wireless mic volume controls turned down, press the VHF wireless system on/off power button so that is in
the On position. The wireless system LED indicator should light up. Switch on each wireless mic in turn – the RF LEDs should light
as a result (if the LED on the transmitter lights dimly, change the battery).
Gently increase the wireless mic volume controls, testing each microphone in turn for output through the speaker. Take care not to
incur “feedback” (a screeching sound that is heard through the speaker) by keeping the microphone at a sensible distance from the
speaker and pointing it away from the speaker. To add some echo to the mics, adjust the echo controls. To add or subtract bass and
treble from the sound, use the Bass and Treble EQ adjustment controls.
If you are not using the microphones, switch the mics off and turn the unit’s VHF wireless power to the off postion to save battery life.
External audio inputs
The units come supplied with external inputs as well as the built-in wireless. 6.3mm jack inputs are provided to connect external
wired or wireless microphones, which are both controlled using the Microphone volume controls.

Stereo RCA phono line inputs are also included on the unit. These can be used to attach line input audio sources such as CD
players or MP3 players (e.g. iPods or smartphones).
External audio output
Stereo RCA phono line outputs are also included on the unit and these will supply an overall mixed output.
Digital media player
The units come with a built-in digital media player. These are straight forward media players that will play from units attached to
either of the built-in USB or SD card sockets. There is also a built-in FM radio.
