NOTICE

Lithium-ion (LiON) batteries are toxic. Please dispose of properly. Some marine suppliers accept old battery packs for recycling and some municipal waste disposal agencies have special provisions for battery disposal.

Alkaline Batteries

There is an alkaline battery tray (P/N CM 110-011) provided with this radio. The alkaline battery tray is provided as a backup or “Emergency” power source should the battery pack run low on power and needs to be recharged. The radio will transmit at full power when using six (6) new AA Alkaline batteries.

WARNING

Never attempt to recharge alkaline batteries. They are not made to be recharged, and should be disposed of in a proper manner.

Maintaining the Battery Charge

As you use your radio, the battery power icon will show the battery power remaining. When the icon begins to flash, it is time to recharge or change the batteries.

NOTICE

Use only the drop-in charger provided by Cobra. Do not use the charger with alkaline batteries; only the LiON battery pack is rechargeable. Spent alkaline batteries must be discarded and replaced.

It is a good idea to keep a set of fresh, high-quality AA alkaline batteries with your radio. Should the rechargeable battery pack become discharged and no electrical power source is available, you can insert the included alkaline battery tray with fresh alkaline batteries and continue to use your radio.

NOTE

Some radios with LiON batteries have AA or AAA battery packs which only allow low-power transmit. The AA battery tray included with the HH475

and a fresh set of alkaline batteries will allow for full-power emergency transmissions.
