Setting Up the Hardware

Attaching the Antenna

The antenna detaches from the radio for easy shipping or storage. To attach the antenna to your radio, screw it tightly onto the anchor post at the top of the radio.

Installing the Battery

Your radio comes with a rechargeable Lithium Ion battery; for shipping safety, the battery is not installed at the factory. The empty alkaline battery case is installed as a placeholder.

1.Insert the hook on the battery into the notch at the top of the battery compartment.

## Note: Each time you remove the battery, check the rubber seal around the battery compartment. Make sure the seal is seated in the groove and there is no dirt or debris on it. If the seal looks worn or damaged, contact customer service to order a replacement (see back cover page for contact information).

2.Lower the battery until it rests flat in the compartment.

3.Bring the battery latch up and snap it into place.

Using Alkaline Batteries

The radio also comes with a battery case that holds four AAA-type alkaline batteries (not included). You can use alkaline batteries as a backup for the Li-Ion battery so you can still use your radio while your Li-Ion battery is recharging. For best performance, Uniden recommends using extra-strength alkaline batteries such as Duracell Ultra® batteries.

## NOTE: When using alkaline batteries, transmit power is limited to a maximum of 2.5 W.

Follow these steps to use the alkaline battery case:

1.Hold the lower part of the case in one hand

with the three battery contacts facing down. Use your thumb to hold the notch on the lower part of the case.

2.With your other hand, grip the upper part of the case and lift the cover open.

3.Align the batteries’ positive and negative terminals with the drawing on the case and snap each battery into place.
