Firmware Update - Sony MAS-A100 Manual

The color of the lamp is the same as the color of the LED lamp on the MAS-A100
(provided the color setting of the LED is not changed from the factory default).
Green (Active): Audio for speech reinforcement is output from the Main output and
Rec output of the MAS-A100.
Amber (Mute): Main output of the MAS-A100 is temporarily silent. The Rec output
audio is output.
Red (Standby): Main output and Rec output of the microphone are silent, and
MAS-A100 temporary settings are reset to defaults. See "5.7 Audio settings" (page
68).
Gray (offline): The MAS-A100 is not accessible from MASM-1. For details about
resolving issues, see "5.1 MASM-1 preparation" (page 47).
Temporary settings
Temporary changes in the microphone gain, muting on/off, and LED lamp on/off on
the [Monitor] tab view are reset to the defaults when the MAS-A100 switches from
Active state to Standby state. See "5.7 Audio settings" (page 68).

6.2. Firmware update

You can update the firmware of MAS-A100 units on the [Update] tab of MASM-1.
Up to 10 MAS-A100 units can be updated at the same time. However, the maximum
number may not be achievable if the network transfer speed between the PC and
MAS-A100 units is low (for example, if local network is not Gigabit speed).
After updating, the LED lamp of the MAS-A100 flashes red and the unit may be reset
to factory default state. For details about initial setup, see "5.2 MAS-A100 initial setup
using MASM-1" (page 49).
