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.
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 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.
