The display orientation may be rotated by pushing the two channel selector buttons
simultaneously. This feature may be used to orient the display according to the operational
needs and enable the user to get the correct orientation independent from how the MP 20 is
carried.
3.9 Output Power Settings
The Polycon MP20 has a standard power output at about 300mW. When the battery is
discharged the output power may be reduced (single band only), and to manually
compensate for this there is an option to enable an
“emergency” full power output setting to
ensure maximum range at the end of battery charge cycle.
Emergency power is entered in menu mode by pressing channel up and volume down. Then
press channel up or down until
‘nP’ or ‘EP’ is displayed.
Normal power is indicated as ‘nP’ and emergency power is indicated as ‘EP’.
To change between normal power and emergency power, press volume up or down.
To store the selection and leave menu mode, press the side PTT button.
Note: Under normal operation and charge status, radios should be operated in ‘nP’.
Note: The EP setting should never be set in MP20-02DB series radios. MP20-02DB series
radios has specified output power until end of battery capacity. The EP setting has been
disabled for MP20-02DB series radios with software version 3.0

Possibility of changing Automatic gain control, default NIVOX/PTT mode, and display orientation is
