How to Troubleshoot NVRAM Broken on a Win CE 5.0 ATM

NH1800CE, MX5000CE, and MX5300CE

Symptom: When ATM is initialized it reads error FFFFF or NVRAM Broken

Cause: The NVRAM Broken error is caused by one of two scenarios:

1) The Main Board was removed from the I/O Board without first installing a battery on the M/B

2) The Battery on the I/O Board is not supplying a good and steady 3.6 vdc to the I/O board.

How to Resolve This Error

Step 1 – Locate the Bat 1 connector on the I/O Board.

Step 2 – Using a Volt Meter measure the voltage on the Battery using the Bat 1 connector. Voltages will

be in DC and should come out to 3.6. This voltage is critical, if the voltage is lower than 3.6 then the

battery is bad and requires replacement before moving on.

***It is suggested that if you must clip tie wrap to replace the battery you should use a new tie wrap to

secure the replacement battery***

Step 3 – Once a good battery is installed on the I/O Board make sure the ATM is powered down and the

vault door is opened.

Step 4 – Push in on the door switch for the vault door and then let go, this will insure that the ATM will

be aware that the door is opened during the next series of steps.

Step 5 – Hold down the top two Function Keys on the left hand side of the display while simultaneously

powering up the ATM

Step 6 – Once at the Master Password Reset Menu you can let go of the Function Keys

Step 7 – Choose RESET

Step 8 – You will get a message asking you if you are sure or not, say YES to the prompt

Step 9 – The ATM will reboot, and when it fully initializes log into the ATM with the default Master

Password (55555).

***At this time it is suggested to back up your EJ either via a Print All Setup or via backup to USB. Also,

it is recommended to go to Reports and do a Print All Setup as once all of the steps below are completed

you will have to reconfigure the ATMs Host Config***

Step 10 – Go To System Setup

Step 11 – Go To System Control

Step 12 – Choose Clear NVRAM

Step 13 – You will be prompted to define what model of Win CE 5.0 you have, please choose the

appropriate one

Step 14 – Choose Clear ALL

Step 15 – Confirm that you do indeed want to Clear All by choosing YES

Step 16 – Once the ATM reboots again and comes back up you will need to log back in again with the

default Master Password and reconfigure the ATM’s Host Config, this should not require new Master

Keys.
