Diagram of signal volume:
Advice; the SQ regulator only functions in the described ways if the received eva-
luation of the CTCSS and DCS pilot procedure is switched off (indicator TSQ can-
not be seen on the display). If it is switched on, the loudspeaker on the equipment
reacts when receiving the suitable pilots only! The MO button also works with acti-
vated pilots and offers the opportunity to listen into the channels.
Transmission/Reception
Press the transmission button on the left side. Your Ex PMR 500 switches from
reception to transmission – indicator TX
Hold down the transmission button and speak clearly from a distance of about 5-
10cms into the microphone.
Loud speech does not improve the report!
Release the transmission button to receive – indicator TX disappears.
Advice; Make sure that you have tuned in a free channel before transmission.
Otherwise other stations will be distorted and you will not be able to hear your part-
ner station.
Search: Finding occupied channels
The automatic search is used in order to find active channels much quicker when
tuning. It scans all 8 channels itself, in the storage operation, all occupied stora-
ge spaces. It stops as soon as a signal exceeds the squelch threshold. Your Ex
PMR 500 remains at this channel for 5 seconds and then begins anew. In addi-
tion the channel indicator flashes. If the signal breaks off before its course of 5
seconds (e.g. if interference is a cause), then it begins its search immediately
without further delay. If one wishes to stay on a certain channel for longer, one
can simply switch off the search.
