Version: v1.14

Date: 2018-04-10

MPR30-ENG

Added “Panel Lock” parameter (under Settings menu):
– When it is set to”Yes“, all the parameters are locked except the Group/Channel/freq & Audio level (MIC/LINE).
– When it is set to “ENC*“, the device loads the Factory Preset and set the expander to ENC-Wis and the LINE level to +12dBu. All the parameters are locked except the Group/Channel/freq & Audio level (MIC/LINE).
fix: bug on the expander settings: after the loading of the preset with a different expander setting (ex. Exp. current ENR-Wis, expander Preset 1 ENC-Wis) , the expander is loaded correctly (ex. ENC-Wis); but after the reboot of the receiver, the device starts with the previous expander (ex. ENR-Wis)

NOTE: FACTORY PRESET settings:
Headphone: -10dB
Squelch: 12dBuV
Expander: ENR-Wis
Tone sq.: OFF
MIC: -18dBu
Sig. Phase: 0
Display contrast: 3 sec
Display timeout: 15 sec
Off timeout: OFF
LED: Full
