CAUTION

Battery Pack Precautions:

• Do not recharge the battery pack if it is already fully charged, as this may reduce its lifespan.

• Do not short the battery terminals or dispose of the battery in fire.
• Do not charge the radio and/or battery pack if they are wet.

Operation

Switching On, Reception and Switching Off

1. To switch on, press and hold the on/off button (1) on the front of the radio.
2. When the radio has passed its diagnostic tests, it will emit a fanfare tone.
3. The radio will enter standby mode, indicated by the LED flashing amber once every 5 seconds, signaling it is ready for use.
4. Adjust the volume control (2) to select the desired volume level.
5. Using the channel buttons (3), ensure you have the correct channel selected.
6. When receiving a valid signal, the LED will illuminate steady green, and audio will be emitted from the radio's speaker or an attached audio accessory.
7. When finished using the radio, switch it off by pressing and holding the on/off button (1) until the radio beeps and the LED/LCD is extinguished.

Transmitting

1. Perform steps 1 through 5 above.

5. For best transmitted speech quality, talk directly into the radio's microphone (9) from approximately 4cm away.
