*: Forced Update

A Forced Update means that any device that connects to the server after the “Effective

Date” shown above must update to the latest “Forced Update” version before holding

a videoconference. All older firmware versions become obsolete, and cannot be used

to hold videoconferences.

**: Optional Update

An Optional Update means that it is not required to install the version shown. Devices

that connect to the server after the “Effective Date” will have the option to update to

the latest version before holding a video conference.

Devices that use different firmware versions can hold teleconferences with each other,

as long as they have already updated to the most recent Forced Update version. (e.g.,

v2.1.1 is compatible with v2.0.3, but not with v1.3.1).

***: Special update method for Ver. 3.0.1

Users who already using Ver2.1.1, Ver2.2.1, and Ver2.3.1 can update directly

to Ver3.0.1.

Note: This RTB was issued as troubleshooting information about a symptom reported on

the domestic model in Japan.

SYMPTOM

Firmware update failure

CAUSE

The bandwidth of the customer’s network is narrow and unstable.

Update the firmware in another network environment, where the bandwidth is broader and

more stable.

For example, bring the customer’s MD-A1b to your office, perform the update there, and

then return the MD-A1b to the customer.

Note: The firmware will be modified to avoid this symptom, and is planned for a March

2012 release.
