In June of 2004 JAMAR began using a battery backed Memory chip in our Hand-held Data Collectors. This
was done in response to the "Realtime Clock Error" that can occur when static discharges across the Data
Collector.

Collector.
The Dallas Memory chip will not stop this discharge
from happening. However, if it does happen the Dallas
chip will save the data that is contained within the
chip, thus saving your valuable data.

The following photographs will show you where to look

First turn your board over and open up the battery

Next, you want to look at an angle into the board. Your looking for a small 'short' of solder. Since this is a retro
fit component, we have to 'short out' two particular traces for the new chip to function properly. The pictures
below show where the 'short' is located. If you have a DB-100, DB-400, or TDC-8 you will be able to see the
short simply by looking through the open battery door. If you have a TDC-12, you will need to unscrew the two
side screws and the bottom screw to remove the entire back plate.

| How to check to see if your Hand-held Data Collector has the Dallas Memory Chip |
If you see the 'short' in the pictured location then you DO in fact have the Dallas memory chip. If you DO NOT see
the short, then you don't have the Dallas memory chip. The Dallas memory chip is an available upgrade to older
boards that did not come with it.
Feel free to contact your JAMAR Representative to find out details.
