5.2.6. Loading factory default settings
In the rare case of needing to restore factory default settings press SET and scroll using UP /
DWN to LOAD DEF VALUES and confirm by SET.
Then select if you want to erase all settings (pressing TUNE) or just one setting value
(SET button). In the case of resetting a single parameter use UP / DWN to select which option
and confirm by SET.
5.2.7. MUTE option
When operating the OM2500A with an Icom transceiver without TX INHIBIT for disabling
TX, we recommend blocking of the TX while tuning using ALC control (mainly while
operating FM /RTTY/ AM).
The ALC Input of your transceiver should be connected to the ALC Out of OM2500A.
Using SET and scrolling UP / DWN select SET MUTE and confirm it by SET. Then
configure MUTE LEVEL for each band so it results in no power being transmitted by TX
when performing TUNE procedure.
