TDC Ultra User’s Manual

14-2

Installing Batteries

The TDC Ultra is powered by four AA cell batteries. Use of low power

electronics in the TDC Ultra makes it possible for the batteries to last for

several months, depending on use.

Eventually, however, the batteries will need to be replaced. The back of the

TDC Ultra contains the battery compartment. The batteries can easily be

popped out and replaced. You should use high quality alkaline batteries,

which you can get at any convenience store.

********IMPORTANT********

Be very careful to observe the proper polarity when installing new bat-

teries. Leaving incorrectly installed batteries in the Ultra can cause the

batteries to burst and leak, damaging the unit.

Do not mix old batteries with new batteries, or mix brands of batteries,

when replacing the batteries. This can cause batteries to burst and leak,

damaging the unit.

You should be able to replace the batteries without disturbing the data in the

TDC Ultra. The memory of the unit is backed by an internal lithium battery,

and is retained even when the AA batteries are removed. Just to be safe,

however, we suggest that you download the data to your computer before

you replace the batteries. You can then clear the memory of the counter after

the new batteries are installed to reset everything properly.

We recommend that you keep track of when you have changed the batter-

ies in the TDC Ultra, and establish a regular routine for changing them.

This should help to avoid having to change the batteries in the middle of

a count.
