Operation
The H25B handheld PA unit can be operated from its internal rechargeable battery, which can be recharged by using the power lead
that is stored inside the rear compartment. When connected to a mains outlet (ensuring correct voltage), the H25B operates from
mains power when switched on (13) and charges the internal battery when switched off. Full charging from empty takes approximately
4½ hours.
An indicator LED ( ) shows when power is on and another (11) shows when the batter is being charged. When not connected to the 10 y
mains supply, the H25B is powered by the internal battery and should offer up to 8 hours operation from a full charge, depending
upon the usage and output volume.
To operate the wireless microphone open the front cover of the beltpack transmitter to reveal the battery compartment (16) , .
(Open this squ ing the sides inward and lever the flap forward). by eez
Place 2 alkaline or NiMH AA batteries inside (ensure + and - are the correct way around) and then fold the front cover back into place
until it clicks shut. Plug in the supplied neckband microphone and screw in the thread until fully connected (14). Slide the OFF/ON
switch (15) to the ON position.
The built-in receiver in the H25B unit is controlled by 2 rotary controls on the con ol panel. When the VOLUME control (8) is turned tr
fully off, the VHF receiver is powered down. Turning this control up activates the receiver and gradually increases the level. When the
receiver detects the signal from the bodypack transmitter, the RF indicator (7) will illuminate. Adjust the VOLUME level to the required
output.
Below the VOLUME control is a TONE (9) control for the wireless microphone. Turning the tone down can help avoid “squealing”
feedback from excessive treble content or turning up will add more treble for clearer speech. Also, a wired microphone or wireless
receiver may be connected to the MIC IN 6.3mm jack socket (6) to be used instead of, or in addition to, the bui -in wireless set. lt
Care should be taken to avoi -of- itioning of the H25B eaker and any microphones being used, which can cause d “line sight” pos sp
feedback (howling or squealing caused by the microphone ‘hearing’ its own output through the speaker). Furthermore, the H25B
should not be positioned too close to the microphone(s) being used for this same reason.
When the wireless microphone is not in use, turn down the OFF/ON/VOLUME control fully down to power down the VHF receiver and
then switch off the bodypack transmitter. Remove the batteries if not being used for long per ds. io
A 3.5mm jack (10) can acce a wired input from any line level audio source, such as an mp3 or CD player. pt
This input is always active, regardless of the media player mode and is not affected by the main VOLUME rotary control (8)
