FM for crystal clear connections
The transmission occurs in frequency modulations (FM) which with UKW radio,
guarantees a lifelike and slighter interference reproduction.
Monitor – function for weak signals
To receive much weaker signals the low noise barrier must bridge the gap.
Lighting Display
All functions of the EX-PMR 500 can be read on the display – eg, the adjusted radio-
channel. The display can be lit up by pressing a button for a better reading when it is
half-light or dark.
Button locking device to avoid errors
The buttons lock themselves electronically. Inadvertent errors will be avoided – like,
e.g. an unintentional change of channel, when the radio equipment is secured by a
belt, and ready for operation.
Double channel surveillance "Dual watch"
Thanks to the double channel surveillance, one can hear from one channel whilst a
different channel is being observed automatically – as a result no call can be missed!
Economical dealings with the accus
An accu saving switch (PS) like an eligible automatic switching off, ensures that the
accus are maintained longer. If it is time therefore, for an accu charging or a change
of accu, it would be signaled on the display.
Sockets for loud speakers and microphone
Apart from the installed loudspeaker and microphone, the sockets allow a combination
of an external loudspeaker and an external microphone or an ear piece/microphone
connection on the top.
Warning, only that of ECOM`s released equipment may be plugged in!
8.3. Power Supply
Before using the ExPMR 500, the accumulator pack must be charged. If the accu pack
is almost completely discharged, the accu symbol will flash. The accu must then be
charged.
Accu charging
- Switch the device off during charging
- The accu may only be charged with the charging device Lt-500Ex* outside the
-
hazardous area.
