8.2. Functions
All 8 channels are very easily changeable.
The Ex-PMR 500 can operate on all 8 channels.
10 storage spaces
So that you always have sufficient regular alternatives for your radio partner.
Search finds active channels
The automatic search (scanner) searches and finds occupied channels where it then
stops.
CTCSS and DCS pilot system
For accurate callings of partner systems, two pilot systems are eligible. In the
CTCSS procedure there are 47 tones or numbers available, in the DCS process,
there are 83 three part numbers.
Acoustic signaling
On request the reception of a suitable pilot can be acoustically (alarm sound)
announced.
Surveillance function
This procedure offers the opportunity to observe people. The Ex PMR 500 reacts to
sound.
Emergency calling mode
To activate the surveillance function, an emergency signal is sent out by pressing the
button PS.
6 varied calling sounds
By pressing the transmission button at the same time as another button, 6 varied calling tones are sent out.
Clone function
With the help of the clone function all of the altered adjustments can be transferred
from an ExPMR 500 (master) to another EX PMR 500 (slave) by the user.
Tone scan mode
This function allows the investigation of received signals depending on which tone
squelch – frequency they contain. This method only operates in CTCSS operations.
Maximal transmission power
The transmission power is 1 Watt and completely exhausts the 500 Watt radiation
licence settings on the integrated aerial.
As a result – according to the surroundings- radio contacts are possible over more
kilometers.
Storage of recent adjustments/alterations
The last channel adjustments can be stored by switching off
(with a charged FM for crystal clear connections
The transmission occurs in frequency modulations (FM) which with UKW radio, guarantees a lifelike and slighter interference reproduction.

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 radiochannel. 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.
- In addition place the radio equipment Ex-PMR 500 in the charging case.
- The red LED on the device indicates that the accu is being charged.
- For conservational charging, the green LED shines.
Advice: The charging socket is deactivated on the side of the equipment.
Accu change
Only the Ex accumulator module Type AM 500 may be used.
- Remove the equipment from the hazardous area
- Open the leather case and remove the Ex PMR 500
- Push the lock LOCK to the front of the device
- Place your thumb on the lid of the accu pack and press and remove downwards.
- Remove the pack from the accu area and carefully remove the plug.
- Warning: Do not pull on the cable!
- Insert a substitute accu and connect.
- Pay attention to a safe engagement of the six pin plug!
- Seal the accu area with a lid, afterwards, the accu area must be secured with
- the lock bolt LOCK.
- Secure the Ex PMR 500 in a leather case and seal completely.
- Warning: Do not carry the substitute accu in the hazardous area!
Accu care
- Before use, the accu should be charged completely.
- Ensure that the maximal capacity of the accu is reached according to approximately
- 6 charging and discharging cycles.
- Since the efficiency of the accu decreases in the course of time, one should
- occasionally discharge it completely so that the full capacity can be maintained.
- In addition the equipment can be left on until it turns itself off. The accu "AM500” must
- be completely charged outside of the hazardous area.
Safety advice
- Do not drop the accu pack, do not damage, do not dismantle and do not
- expose to unauthorized temperatures (-20 to +50 deg C)!
- Only charge the pack as described in the operating instructions!
- Never leave a discharged pack for a long time in unused equipment!
- Do not store the pack for longer than 6 months without discharging and
- recharging in the meantime!
- Under no circumstances must one throw the accu into an open fire or into
- domestic rubbish!

8.4. Integrated aerial
The Ex PMR 500 is delivered with a flexible integrated rubber spiral aerial and must
only be used with this aerial!
This integrated aerial is insoluble via a SMA socket, when connected with the radio
telephone device.
Advice:
- Never send without the integrated aerial!
- The final transmission stage of your radio equipment could become
- damaged on other ways!
- Never place the radio equipment on the aerial!
- The connection of another aerial is a punishable offence!
8.5 Operating elements and connections
In this section the meaning of the single connections and buttons will be explained in
great detail. Please take the positions described on page 4.
Connections and regulator on the top
➀ VOL/OFF
With the inner part of the double regulator, switch the radio equipment on or off and
adjust the volume. The radio equipment is switched off if this regulator is on the left
side. To switch on turn to the right (click).
Turn the regulator clockwise in order to raise the volume.
Warning: Do not turn the loudspeaker on too high, especially for operations using
headphones!! Ear damage could be consequential!
➁ SQ
Regulator for low noise barrier. This has no function for pilot procedures CTCSS. On
the left side the low noise barrier is switched off.If you turn the regulator clockwise then
the level recorder of the low noise barrier is raised. The low noise barrier should be
installed so that no murmurs sound from the loudspeaker.
➂ 3. Integrated aerial/aerial connections
The integrated aerial is connected to this SMA socket.
➃ 4. Sockets MIC and SPK
Under the protective cap the connections for an external microphone MIC and an
external loudspeaker SPK can be found. If this is used e.g. as equipment containing
speech, the internal microphone or the internal loudspeaker will be switched off. If the
sockets are not used, cover them with protective caps so that neither spray water nor
dust can enter.
Warning: One may only use equipment that has been released for operation for the
ExPMR 500 by ECOM.

Operating elements on the left and right as well as the back
➀ 1. Transmission and receiving change over, PTT Button
If you press the PTT button, it should change from reception to transmission. Let
go of the PTT button in order to change it back to reception.
Advice; The abbreviation PTT stands for "push to talk”.
➁ 2. FUNC button functioning
Some buttons have two functions. Their second function is available as long as
though the FUNC button is pressed – indicator F, top left on the display.
Buttons on the front
➀ MO/Fr/Ch
This button has many functions:
- By directly pressing this button, the low noise barrier can be bridged as long as
though the button MO is then released.
- If the button is pressed for longer than one second, statistical information will be
received one after the other for the different pilots as well as the search
jump-function.
After work the indicator receives rc off and tc off for switched off CTCSS
operations as well as SCSP off, because no channel is marked to jump.
For a switched on operation and activated sound squelch, rc and tc will be
indicated as well as the switched on CTCSS sound. If a channel is marked
to jump, then indicator on01 will follow from SCSP (for channel one in this case).
Afterwards the frequency can be read from the display.
- For the second function, the frequency and channel indicator can be changed on
the large display. Hold the FUNC button (indicator F) and simultaneously press
the MO/Fr/Ch button.
➁ (DOWN) / TS
This button has two functions;
- By pressing this button , the channel or frequency can be switched back in one
step. The button has a replay function. If it is pressed for longer, the channels
will regularly be switched back downwards.
- When using the second function, the CTCSS pilots or DCS code for reception
and transmission or general sounds can be indicated and then altered.
➂ (UP) / TO
This button has two functions;
- By pressing this button directly, the channel or frequency can be switched
upwards in one step. The button has a replay function; if it is pressed for longer,
the channels will be switched back up.
