  • Added compander alignment with transmitter during SYNC operation

WARNING:
to upgrade from version 1.11 to version 1.15 it is necessary to perform an intermediate upgrade to version 1.12!
therefore do an upgrade from 1.11 to 1.12 and then from 1.12 to 1.15

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
