6 Advanced Functions (EXTRA Menu)

To retrieve the other results press

or briefly. Dropouts are indicated like this (Ex-

ample 1):

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.

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 nec-
essary.
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 trans-
mitter is off the air.

The higher the squelch threshold (-86 dB = max., -100 dB = min.), the lower the sen-
sitivity of the receiver and thus the usable range between transmitter and receiver.
