Service Memo Notification

Public | Finalized Published: 24 August 2009 - Reference: 26_2010_SM

Keypad locked in reprogramming sequence

The keypad for Series 1 range of display units has a built-in hotkey (holding the "+" button active for at least 5 seconds, while powering the unit) to let the keypad reprogram itself (the keypad features a micro controller which uses its own firmware).

But if there is no new firmware prepared to be loaded into the keypad, it will be locked in the reprogramming sequence and clear its own memory. This is indicated by 4 green LEDs turned on in a cross indefinitely. Please see below for solution on how to solve this behaviour.

In rare cases, we have seen units with this failure for no good reason, the immediate solution is the same for these (root cause analysis ongoing).

Solution:

1. Contact our helpdesk department. Make sure to write down the typenumber, serial number (located in rear of the unit) and firmware version (via the OSD menu) of the unit.

2. Hatteland Display will provide instructions and binary files for updating the keypad firmware.

3. If the upgrade was unsuccessful, the keypad needs to be sent to our factory for investigation.
