Preparation:
I
Carefully read the entire installation guide and keep it nearby for reference
I
The update preparations are described in a separate „preparations for update“ guide
(recommended read for first-time updaters)
Important information:
I
Do not disconnect the device from the power supply during transfer communication of the updates. Also make sure that it doesn’t
get coincidentally disconnected.
I
It’s mandatory to closely follow this installation guide step-by-step. Even a small deviation may render your device
permanently unusable.
I
Do not unplug your USB data carrier during the update process.
I
Do not use any updates which are not expressively certified for your ZE-MC294 (i.e. no updates from similar models).
If you deviate from these step-by-step instructions, you will void your warranty and risk to damage your device. In that case
ZENEC will not take any responsibility.
Installation of the firmware updates:
The update software consists of three parts on three sticks i.e. MPEG, BT, MCU. Make absolutely sure that you install all
software parts following the below mentioned installation sequence:
1. MPEG
2. BT
3. MCU
Caution: Ensure your cell phone is switched off during the entire update process – any Bluetooth activities, as Bluetooth
coupled phones receiving incoming calls, are prone to fatally interrupt the update process.
1. Installation Part -> MPEG
a. Plug in the first USB data carrier labelled „MPEG“ into the running ZE-MC294.
b. The update will start automatically. Progress is numerically displayed.
c. Do neither switch off the ZE-MC294 nor unplug the USB stick during the update.
d. This update is finished as soon as the ZENEC logo is displayed.
e. Now switch off the ZE-MC294.
f. Remove that USB-stick and continue with part two.
2. Installation Part 2 -> Bluetooth 3.60
a. Plug in the USB data carrier labelled "BT“ into the switched off ZE-MC294.
b. Now switch on your device.
c. The update starts automatically now. Progress will be displayed numerically.
d. Neither switch off the ZE-MC294 nor unplug the USB stick during the update.
e. Wait until the process has finished. The device will then switch off by itself.
f. Switch your ZE-MC294 on again and continue with part three.
3. Installation Part 3 -> MCU
a. Plug in the USB data carrier labelled „MCU“ into the running ZE-MC294.
b. The update will start automatically. Progress is numerically displayed.
