If you release the button, the Ex PMR 500 stops at the corresponding channel. A
continual channel/frequency change will not receive simultaneously!
Storage-operation: input
Your radio equipment offers 10 storage spaces which are labeled with digits from
01 to 10. In storage work, you can store e.g. all channels exclusive of the alter-
native channels with possible interference and then observe the search either
manually or automatically.
(EMPty).
Now adjust the desired frequency by using the DOWN M or UP L button.
If CTCSS tones and analysis are stored for this, they can likewise be adjusted.
- Hold the FUNC button and simultaneously press the MR/MW button.
Select the desired storage space by using the UP L or DOWN M buttons (MR
and storage space number flashes).
- Confirm with the PTT button (MR and storage space number will stop flashing)
Use the MR button to return to tuning.
Storage work: call
The storage spaces are called in succession in the storage operation;
Change tuning with the MR/MW button in the working and select the desired sto-
rage space by using the DOWN M or UP L buttons.
Occupied storage spaces can be seen by the indicator MR on the right of the

Low noise barrier/squelch
Your Ex PMR 500 is fitted with an adjustable low noise barrier (squelch), which
restrains the tiresome noise to a free channel when waiting. As a result, the
battery power is saved. The low noise barrier can be reconciled with the MO
monitor button on the radio equipment.
The place from where the signal volume widens the low noise barrier can be
adjusted with the SQ regulator on the top of the equipment. If this is found on the
left side, the low noise barrier is switched off. The more the regulator is turned to
the right, the stronger the signals must be in order to switch to a repetition.
In order to hear very soft signals, which lay just between low noise and squelch
location (see marking), turn the regulator to the left.
channel where only a low noise can be heard.
Then turn the SQ regulator clockwise until the noise disappears – ready.
The broken noise barrier can be recognized visually by the indicator BUSY on the
display. In case the signal volume of the partner station falls under the squelch
threshold during a conversation e.g. if you hear your partner move past a "radio
shadow", you should press the MO button. Thereby, in many cases a "chopped
off" reception is avoided. Signals which are in the low noise (see labeling) can no
longer be heard when pressing the MO button. The working of the low noise
