Samsung WAM551-ZA - Manual (Page 55)

` Speaker Auto Update
Shows the M5's current software version, and lets you turn auto update on or off.
• On : When on, automatically updates the software when new firmware is released.
• Off : Turns off the auto update function.
NOTES
9
Auto update is available when your M5 is connected to a network and the Speaker Auto Update
function is set to On.
9 It is strongly recommended that Speaker Auto Update settings on all the M5s used are set to On.
Problems with networked functions (such as Group Play and Ear to Hear) may otherwise occur due
to incompatibility issues when a variety of M5 software versions is used on linked M5s.
9
For each M5 with an outdated software version,
1) set the Speaker Auto Update setting to On and
2) press and hold the Mute button for more than 5 seconds.
The M5 will then turn off and on so as to update its software automatically.
