HF-TWIN RECEIVER
•
While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
•
Switch off the HF-MIC by pressing the ON/OFF switch (4) for a second. The display (2) will shortly show
“OFF” before shutting down the microphone.
•
The power of the RF-signal can be changed with the LO-HI selector (6) from LO (5dBm -3,16mW) to HI
(10dBm-10mW) to get a better reception of bigger distance range.
HF-BPACK
– SETUP
•
First switch on the HF-TWIN RECEIVER and select a channel (1-8) for receiver A or a channel (9-16) for
receiver B.
•
Open the battery compartment (4) of the HF-BPACK by pressing gently at the sides of the cover and pull-
ing it backwards and insert two AA batteries (1.5V alkaline or rechargeable).
•
Switch on the HF-BPACK by pressing the POWER switch (3) for a second. The display (2) will light up.
•
Hold the IR-sensor (7) of the HF-BPACK in front of the IR-indicator (2) of the HF-TWIN RECEIVER.
•
Press the IR-KNOB A (6) or the IR-KNOB B (8) on the HF-TWIN RECEIVER for about 2 seconds. The IR-
indicator symbol (H) will start blinking 3 times. When the blinking stops, the HF-MIC has received the
channel information from the HF-TWIN RECEIVER and will now work with this part (A or B) from the re-
ceiver.
•
Do the same for a second HF-BPACK if you want to use 2 belt pack microphones.
•
Connect the lavalier microphone or optional headset on the mini-jack connector (5) of the HF-BPACK.
•
Speak through the mic: the AF indicator (A) will flash to the rhythm of your voice.
•
While checking the system, walk around to check if you encounter any dead spots (no reception): in these
cases, try to change the position of the receiver.
•
Switch off the HF-BPACK by pressing the POWER switch (3) for a second. The display (2) will shortly
show
“OFF” before shutting down the belt pack.
TROUBLESHOOTING
Problem
Solution
No sound
•
Check the power supply of the microphone and receiver.
•
Check if the transmitter and receiver are tuned to the same channel (frequency).
•
Check if the hi-fi appliance or audio mixer is switched on and the receiver output is
connected to the desired audio input. Mixer: is the gain open?
•
Check if the transmitter is too far away from the receiver.
•
Check if the receiver is located near a large metal object or if there are large obstruc-
tions (ex. large metal object or thick wall) between transmitter and receiver.
Sound interference
•
Check the antenna location.
•
When using 2 HF-TWIN RECEIVERs simultaneously, make sure that the selected
channels don’t interfere: select another channel pair on one of the receivers.
•
Check whether the interference comes from other wireless microphones, TV, radio,
PC, etc.
Distortion
•
Check if the receiver volume level is set too high or too low.
•
Check if the interference comes from other wireless microphones, TV, radio, PC, etc.
CLEANING THE APPLIANCE:
Clean by wiping with a polished cloth slightly dipped with water. Avoid getting water inside the unit. Do not
