Rehearsal - Soundcheck
The REHEARSAL function detects a maximum of six dropouts and
records the time each dropout occurred, the minimum field strength
at each antenna, and the maximum audio level. You can view the list
of results after the recording has stopped.
1. From the "RHSL" screen on the receiver, select "START" to start the
recording.
2. Move the transmitter around the area where you will use the sys-
tem to check the area for "dead spots", i.e., places where the field
strength seems to drop and reception deteriorates.
3. Play a few bars on your instrument (the louder the better).
4. You can stop the recording at any time by pressing l briefly.
Possible indications:
"D1": The recording has been completed, the display indicates
dropout no. 1.
"MIN RF": The recording has been completed, no dropout has
been detected. The display indicates the minimum RF level
measured.
"OVFL": The recording has been stopped automatically because
six dropouts have been detected already or because the available
time (16 minutes) has elapsed.
•
To retrieve the other results press t or u briefly. Dropouts are
indicated like this (Example1):
Example 1: Dropout no. 1 occurred after 124 seconds.
•
The first storage locations are assigned to dropouts, the last two for
the lowest RF level and highest audio level measured (Examples 2
and 3).
Example 2: Minimum RF level: -85 dB
Example 3: Maximum audio level: -5 dB
•
The last item in the result list is followed (the first item preceded)
by the "EXIT" option.
•
You can avoid dropouts by placing the receiver or antennas in dif-
ferent positions.
•
If the RF bar is off and the RF MUTE LED is red, no signal is being
received or the squelch threshold is too high.

Squelch
•
If the receiver finds no clean frequency, check your antenna setup
(cable lengths, booster, power splitter, system wiring).
•
If this is correct and there is still a stable RF noise floor you can try
to increase the squelch threshold slowly from -100 dBm to -86 dBm
to avoid noise when the RF signal is weak. Make sure never to set
the squelch threshold any higher than absolutely necessary. The
adjustable squelch will mute the receiver if the received signal is
too weak so the related noise or the self-noise of the receiver will
not become audible while the transmitter is off the air.
i
The higher the squelch threshold (-86 dB = max., -100 dB
= min.), the lower the sensitivity of the receiver and thus
the usable range between transmitter and receiver.
Pilot Tone
As long as this function is active, the received signal contains a con-
tinuous signal at a predefined frequency (a pilot tone). If the receiver
detects no pilot tone, the receiver's audio output will be muted.
Factory Reset
•
To reset all parameters to their factory default settings, use the
"FACTORY RESET" screen.
The INFO screen lets you call up information about your receiver:
- "V1.1": firmware version
- "B 4--.50": frequency band
- "PV 1.0": Preset version
- "INTRO": This screen allows you to edit the name displayed upon
switching power to the receiver ON.
Intro
The "INTRO" sub-menu lets you enter and save a new name at any
time. You can select any combination of up to 16 letters and numerals.
1. Select the "INTRO" screen. The first character starts flashing.
2. Use the arrow keys to select the desired characters.
