5. Replace the cover, inserting the lower tabs first.

When BATT.Lo flashes and the scanner beeps every 15 seconds, replace all four batteries.

Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them.

Using Rechargeable Batteries

You can also use four rechargeable batteries. Before you use Ni-Cd or Ni-MH batteries, you must charge them.

The scanner has a built-in circuit that lets you recharge Ni-Cd and Ni-MH batteries while they are in the scanner.

To charge the batteries, set ALKALINE JACK NI-CDto NI-CD, install the batteries in the scanner, and connect an external AC or DC adapter to the scanner’s POWER jack (see “Using AC Power” on Page 13 or “Using Vehi- cle Battery Power” on Page 14).

Warning: Do not connect either adapter to the scanner if non-rechargeable batteries (such as alkaline batteries) are installed in the scanner and ALKALINE JACK NI- CD is set to NI-CD,or if you are unsure of the switch’s po- sition. Non-rechargeable batteries will get hot and can even explode if you try to recharge them.

Before you use Ni-Cd or Ni-MH batteries for the first time, charge them at least 24 hours to bring them to a full charge.

Discharged batteries take about 10 to 18 hours to fully recharge. If you use the scanner while the batteries are charging, charging takes longer.

Notes:

•Ni-Cd batteries last longer and deliver more power if you occasionally let them fully discharge. To do this, simply use the scanner until it beeps every 15 sec- onds and BATT.Lo flashes.

•To prevent damage to Ni-Cd batteries, never charge them in an area where the temperature is above 113°F (40°C) or below 40°F (4°C).
