5. BATTERY REPLACEMENT

Low Battery Warning

The message, "Low battery" appears whenever battery power drops below a certain level (about
2.70 V). Replace the main battery immediately after this message appears.
Whenever the low battery warning message appears, the OFF key will be the only function that
works. If you don't turn the unit off yourself, power will switch off automatically about 30 seconds after
the low battery warning appears.

Replacing Battery

Main Battery
One CR2032 lithium battery is used for the main power supply. The unit will not operate at all if
main battery is not installed.

Back-up Battery
One CR2032 lithium battery supplies power to the memory and protects its contents.

Memory contents are lost when both the main battery and the back-up battery are removed. Be sure
always to leave one of the batteries in place to protect memory contents. If, however, you remove the
main battery for any time, memory retention will depend entirely on the condition of the back-up
battery. Over a long period of time with just the back-up battery in place, memory contents are likely
to be damaged. If memory seems corrupted, clear it using the RESET procedure described in section
4.

Important!

Incorrect use of batteries can cause them to burst or leak, possibly damaging the interior of the unit.
Note the following precautions:

Be sure that the positive (+) and negative (-) poles of the batteries are facing in the proper direc-
tion.

Never leave dead batteries in the battery compartment.

Remove the batteries if you do not plan to use the unit for a long period of time.

To avoid damage to the unit from leaky batteries, replace the batteries at least once every five
years, no matter how much you use the unit during that time.

Warning!

Never try to recharge the batteries that come with the unit.

Do not expose batteries to direct heat, short-circuit them, or try to take them apart.

Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.
