see further in this manual.
a. This is the currently used antenna, A is ANT 1 and B is ANT 2.
b. RF: this meter shows the radio frequency signal level. If the transmitter is ON the meter must be
close to the top. If the transmitter is OFF the meter is completely down. In this condition, if some
signal is shown on the meter it means that there is a RF disturbance: to avoid it you must select a
different RF channel.
c. MUTE: when this symbol is on the transmitter is muted and no audio signal is send out to the mixer.
If no RF signal is present, automatically the receiver unit activates the mute. When a RF signal is
present, the mute can be enabled or disabled only from the transmitter units.
d. AF: this meter shows the audio frequency signal send to the outputs. If no AF signal is present when
the user speaks into the microphone, check the RF and MUTE indicators. If the MUTE symbol is on,
disable the MUTE from the transmitter. If the RF signal is null, check if the transmitter is operative
and if it's set on the same RF channel as the receiver.
e. This is the number of the selected channel: there are 99 RF channels stored in the receiver memory.
These channels have been chosen to avoid interferences between RMW821 systems in order to make
possible the use of 6 simultaneous systems (see RMW821 MENU OPTION for detailed operations).
f. This is the RF frequency selected for the receiver: it must be the same as the transmitter frequency.
The frequency can be chosen in the 821-832 and 863-865 MHz frequency ranges (see RMW821
MENU OPTION for detailed operations).
g. When lighted this symbol indicates that the receiver is in lock state: when the receiver is locked only
the SET button remains operative to unlock the unit.
h. These are the menu option, see the following chapter.
