Clean the transceiver thoroughly with fresh water after exposure to saltwater, and dry it before operating. Otherwise, the transceivers key, switches and controllers may become unusable due to salt water crystallisation.
Note: Do Not submerge the transceiver in water if there is any reason to suspect the waterproof protection may not be effective. For example, in cases where the battery cover or DC Jack cap rubber seal is damaged, the transceiver/battery cover/DC jack is cracked or broken, or if the transceiver has been dropped, or when the battery cover, antenna or DC Jack Cap are detached from the transceiver.

An LED sends out intermittent light from a transparent section on the bottom of the radios, while floating in the water.

1. Connect the adaptor to AC power.
2. Rotate the connector cap on the top of the transceiver to expose the charging socket.
3. Plug the AC Adaptor plug into the socket on the top of the transceiver. LCD will indicate charging in progress.
4. If battery charging is full, LCD appears “FL”, you should remove the adaptor. NOTE: If you have not inserted the battery pack, the LCD will show “Er”.
5. When charging is complete, remove the plug from the radio and replace the cover ensuring it is fitted correctly.
