8.7. Operation

Radio equipment switching on/off
The Ex-PMR 500 is switched off and on with the knob VOL/OFF on the top. If this
is on the left side and there is no indicator on the display, the radio device is swit-
ched off. To switch on, turn the regulator 90 degrees clockwise.;
The equipment switches on with a click and the last installed channel appears on
the display e.g. CH 1 for channel 1 or the last tuned in frequency. At the same
time, you will hear a greeting melody.

Adjusting volume

Firstly, put the regulator on the top left. Then put the outer regulator on the left –
the low noise barrier is turned off. Carefully turn the regulator VOL/OFF to the top
in a clockwise direction. You will hear a loud noise emerging.
Advice; Adjust the volume so that you can hear the partner station well. The gre-
ater the volume is adjusted, the greater the electricity consumption. Take care
when adjusting the volume, that no-one is disturbed by the reproduction.
Tuning in and memory work
When tuning in, your radio equipment offers the reception and transmission pos-
sibilities of all 8 frequencies. Above that, there is the memory operation in which
the operation is limited to a maximal 10 previously stored frequencies. Alternate
between tuning in and memory work with the MR/MW button. The storage work
is characterized by the indicator MR on the right of the display. As detailed below,
the tuning in and then storage operation is explained.
Tuning in; channel and frequency indicator.
You can only build a connection with radio equipment which is tuned into the same
channel or same frequency. Your radio equipment offers either the frequency or
channel indicator on the display. For the frequency indicator the exact transmis-
sion and reception frequency is shown in MHz e.g. 446.0062 MHz. The channels
are labeled continuously from 01 to 08 and change between frequency and chan-
nel indication or vice versa;
Hold the FUNC button and simultaneously press the MO/Fr/Ch button.
Tuning in; channels /frequency adjustments
Adjust the desired channels/frequencies by using the UP L or DOWN M buttons.
- Press button UP L for a higher channel number/frequency adjustment..
- Press the DOWN M button to find the lower channel/frequency number
Each channel/frequency change is accompanied with a reception tone.
The buttons have a replay function; If you press the UP L or DOWN M button
for longer, you can continuously switch further.
